Re: Fwd: Can you help me with this Python question?

[Axy via Python-list]

Well, although I never used pandas and never will, if that's about 
artworks, that's mine.


Obviously, you need to iterate columns and sum values returned by the 
snippet you provided. A quick search tells us to use colums property. 
So, it might look like this:


na_sum = sum(df[name].isnull().sum() for name in df.columns)

What in particular is a "Python dialog box"? Python doesn't, of its
own, have dialog boxes. Add-on libraries: Tkinter, wxPython, the win32
extensions, et al. allow one to code scripts that produce dialogs, but the
dialogs are specific to the library.

"pythonw" is the name of the interpreter meant for use with programs
that do not use console I/O -- IOW, pure GUI (one of the aforesaid
libraries).

Normally such programs are given the extension .pyw rather than .py --
and (at least on my system), .pyw files are automatically associated with
pythonw. Just providing the script name with extension is sufficient.
Though there is the matter that giving said name in a command line prompt
means one still has a console active. .pyw files are meant to be started
from the file explorer by double-clicking on them, and one doesn't want to
have a console window popping up if it is never used (which is what happens
if one double-clicks on a plain .py file).


HOW did you "set up Windows to run this batch file upon startup"?

Windows used to support (and still does if
https://www.thewindowsclub.com/startup-folder-in-windows-8 is correct
[ignore the -8, the site is updated for 10/11]). This is per user start up
(unless one uses the "all users" path). The Windows task scheduler also
allows one to create tasks that run on a schedule -- said schedule
including options for specific user logging in, any user logging in,
computer start-up, etc. The scheduler is probably the recommended way to
set up things.

As I stated above -- insufficient information.

Is Python installed for all users or just one?
Is "pythonw" on the system PATH?
Is the script meant to only run for one user or any user?
How was the script configured to start?
Is the script in a valid directory (I believe in a previous post it was
mentioned that you had the script in the directory used for per user
START-MENU entries; that is not meant for user files!).

My first approach would be to open a console and run the script
manually (not the BAT file) -- does any error message appear in the
console? Running using pythonw suppresses console, error messages would be
lost -- GUI applications are expected to trap any runtime errors and either
write to a log file or pop-up a dialog for them.

Then, after getting it to run in a console, I'd try it by
double-clicking on the file (rename it to .pyw so you get the no-console
interpreter). If Windows says it doesn't know how to run .pyw, it implies
that there is no file association set up in Windows telling it how to run
that extension.

NO BAT file should be required for a one-liner that does no parameter
substitution.

If using the "startup" directory method, create a shortcut for the
script (right-click, drag, create shortcut here). Right-click/Properties.
If you don't have associations set to run that extension type, prefix the
Target box with the path to the python(w) executable. Move the shortcut to
the proper startup directory -- Note that if you put it in the all-users
startup, you have to make sure that the script and shortcut themselves are
not in protected (single user) locations.

Hello dn,

Thanks for your reply.  My apologies, I should have provided more background 
information.

I was recently running a Windows 10 machine and I believe it was running Python 
3.8.  All I did was create a batch file titled Start-AIG.bat which simply 
contained the following: "pythonw AIG.py".  It started a python program titled 
"AIG.py" and the Python dialog box was displayed on my screen, running all day 
and night.  I set up Windows to run this batch file upon startup and it worked 
fine.  I remember having to do a bunch of research before I learned that I 
needed to put "pythonw AIG.py" in the batch file as opposed to "python AIG.py".

However, my old windows 10 desktop crashed and I have a new Windows 11 machine. 
 I installed the latest stable version of Python, which is 3.10.  Now, when I 
try to execute the same batch file, it doesn't launch the app.  It could be 
because I'm using Windows 11 or could be because I now have a newer version of 
Python.

With this additional information, do you have any ideas what I should do to get 
the Python script running in the same way I had it running before?

Thank you!

Brent

Personally, I write a batch file containing the 'python

assumes python.exe is on the Windows path.


Once tested and working it lets me edit the batch file to adjust the 
payload without having to touch the Windows stuff again.

ONE: that path indicates that you installed Python "for current user
only".

TWO: that is the path for the short cut entry that shows up on the
Windows "Start Menu" (whatever that looks like on Win11). It is NOT a
location for user scripts.

Python, at heart, is a language interpreter that is invoked from a
command line shell. (Use  to exit the interpreter if you are trying
the below examples -- otherwise you'd add the path/name of the script file
to the command line)

It can run from scripts invoked by double-clicking on the file in the
"file explorer" but often the results are not as desired (it will pop up a
console window -- but that window closes as soon as the script exits!).
Scripts written using one of the graphical libraries (Tkinter, wxPython,
etc.) are typically given a .pyw extension -- .pyw is normally associated
with an alternate start-up module which suppresses the console window.

Editing of scripts can be done with one's favorite programming text
editor. If one can't live without having some sort of IDE, look for
something called IDLE to be on your start menu (IDLE is actually a Python
script using Tkinter).

Short answer: the same way you would run ANY application at start-up. 

Longer answer: this is a feature of the OS, not Python. You will need
to learn how to use the OS. Maybe start with

You didn't give any context and say what package you're using!

After searching for "RandomForestClassifier", I'm guessing
that you're
using scikit.

 From the documentation here:


https://scikit-learn.org/stable/modules/generated/sklearn.ensemble.RandomForestClassifier.html#sklearn.ensemble.RandomForestClassifier.fit

it says:

     Returns: self : object

so it looks like clf.fit(...) returns clf.

That being the case, then, yes, they're equivalent.

The problem is if I post to a mailing list from gmail (either the web
interface or Thunderbird via Google's SMTP servers), Google will
silently discard my own message when the list serv echos it back to me.
In the web-based "conversation" view, Google puts my own sent message in
the conversation. However via IMAP I see nothing.  Thus when looking at
my list mail on Thunderbird, my own messages to the list never show up.

Does that make sense?  There was a lot of fuss about this when gmail
first started doing this, but Google ignored it and continues to ignore
this issue. They regard this sort of email use as "legacy."

Here's an old message describing the problem and showing Google's
non-response:
https://support.google.com/mail/forum/K7un8RUduyrfxS01ac/?hl=en

The only way to prevent this is to send your message via a non-Gmail
SMTP server, and not to put those messages in your Gmail Sent folder.
This runs the risk of messages being flagged as untrustworthy, but as
long as Python's smtp server accepts them, it works.  Of course python's
list messages going out are often flagged as suspicious because they
have our own "from" addresses on them but come through Python's servers.

No the problem has nothing to do with the web interface or the client.
It's a bug/feature of the Google back end.

In Gmail's case it's a matter of not using gmail at all, as their
mailing list -breaking behavior happens whether you use IMAP and
thunderbird.  I work around gmail's breakage right now by using my own
SMTP server for sending messages to the list, so gmail won't recognize
my messages and discard them.

I could leave gmail, but it's not worth it for me at this point.  Python
is the only mailing list left of all the open source projects I used to
follow. It's pretty sad how they all abandoned a format that works very
well for web based formats.

For me, "news" works even better than email, which is why I read all

No thanks. I don't want to be on yet another web forum.  I don't need
"social media" or a "social media app."  Email works exceedingly well
for this sort of thing, despite Google's antics.

Sadly a lot of open source projects are abandoning the good old list and
moving to awkward web forums like Discourse.

With e-mail lists, everything is right here in my email client
(Thunderbird), separated out into folders with procmail (or whatever
filtering system you want), and with proper nesting of messages.  No web
forum I've seen offers this convenience or proper nesting.  Electronic
communication is fraught enough. "Social media" (whatever that means)
seems to just make it harder.

You can get the source code from pypi. I don't see any option for pip to
do that, but you can easily do it manually.

If you don't trust the binaries from pypi, don't trust the source code
either! Malware has been found on npm, for example. So to be sure there
are no backdoors you have to (carefully) read the source of each module
you use (which makes the time for downloading them manually trivial).

Oh, and you have read "Reflections on Trusting Trust", I presume?

It's still open source if the source is available (under the usual
conditions). Whether you trust somebody else to compile the software is
a question of trust, not of openness. Do you trust the person who
compiled your compiler?

That is fine if you dont like something. You dont have to help me out if you 
dont want to. But trying to censor me is unethical. Hopefully other people will 
have the logic to make decisions for themselves and give me help on python if 
they choose to do so.

I hope my reply does not get censored. I am being reasonable here. And if you 
are wondering why I am "paranoid", you would be too if you are dealing with a 
server that might host a hot wallet. I dont want my server getting hacked just 
because I was too lazy to compile my own code. And it is not uncommon for 
binaries of open source projects to be injected with malware.

Python question

[Mr. Lee Chiffre]

Thank you Marco for at least taking the time to read my message even if
you do not agree with me on things. And no disrespect to you. But I came
here for python related questions and help. Not to be called suspicious
and untrustworthy only because I am concerned about security of users and
for being a advocate of privacy. Then to call for me to be censored is
just ludicrous.

I said I am a python noob. This is why I asked for help. And I see no
issue in offering payment for a programming task.

> 2. he does not trust binaries from pip.

What is the point of open source if you cannot compile from source code?

> 3. I don't trust any cryptocurrency.

Not unusual. People use open source because they dont trust closed source.
Binaries that someone else compiled is not open source.

Roads and cars are used by drug dealers. Stop using roads and cars. Cash
is used by criminals. Stop using cash. Internet is used by child abusers.
Stop supporting the internet. I am offended that you group me with
criminals and baddies because I support technological privacy.

That is fine if you dont like something. You dont have to help me out if
you dont want to. But trying to censor me is unethical. Hopefully other
people will have the logic to make decisions for themselves and give me
help on python if they choose to do so.

I hope my reply does not get censored. I am being reasonable here. And if
you are wondering why I am "paranoid", you would be too if you are dealing
with a server that might host a hot wallet. I dont want my server getting
hacked just because I was too lazy to compile my own code. And it is not
uncommon for binaries of open source projects to be injected with malware.

The parens on the right are superfluous:

>>> a
'foo'
>>> b
'bar'

You may also do the post-processing in Python, which allows you to avoid the 
shell completely:

>>> output = subprocess.check_output(["/bin/df", "--output=pcent,ipcent", 
"/var"])
>>> output
b'Use% IUse%\n 85%   16%\n'
>>> a, b = output.replace(b"%", b"").split()[-2:]
>>> a
b'85'
>>> b
b'16'

If you want integers:

>>> a, b = [int(v) for v in output.replace(b"%", b"").split()[-2:]]
>>> a
85
>>> b
16

Re: Basic python question

[Jagga Soorma]

Thanks Aldwin that helps but it looks like it is reversing the numbers
for some reason:

the df command returns the following:
7  2

I used your example and did:
x,y = set(output.split())

My assumption would be that x should be 7 and y should be 2.  However,
when I print x and y it seems to be reversed (x is 2 and y is 7).  Am
I missing something?

Thanks

Basic python question

[Jagga Soorma]

Hello,

I am new to python and trying to do some basic things with python.  I
am writing a script that runs a df command and I need parts of that
output saved in 2 different variables.  Is this something that can be
done?  I can do this by running multiple df commands but would prefer
to make only one call:

--
inode_cmd = "/bin/df --output=pcent,ipcent /var| grep -v Use | tr '%' ' '"
output  = subprocess.check_output( inode_cmd,
stderr=subprocess.STDOUT, shell=True )
--

But this would end up giving me the following:

#df --output=pcent,ipcent /var | grep -v Use | tr '%' ' '
   5   1

I would like variable x to be 5 and variable y to be 1.  Is there a
easier way to do this?

Thanks in advance for your guidance.

I've done that there is nothing wrong with them the error comes when writing 
out to the canvas, and i rounded them so it is integer pixels. To be honest i 
think there maybe something with the canvas that goes wrong. A block of fixed 
length can't expand. I run console.logg()  barLength=xFrontStart-xBackEnd and 
it is constant at every call within if clause.  It is just that when canvas 
write out the values apparently the draw rectangle function somehow hold other 
values.

Well i restart the whole render programming, doing it right from start this 
time reading values from the record buffer and see if the animation problem 
magically dissapear. It could be something undefined affect the the variables.

Please don't; this forum should primarily be used for discussing Python.

I appreciate that you have tried another forum for JavaScript, but
that's unrelated to whether this is an approriate forum for the

You could try https://stackoverflow.com/tags/javascript> but really
it's not good to be using this Python discussion forum for that purpose.

xFrontStart=scrollBarPos-FRONTOFFSET; somehow executed  more then once after

only done once???

Sending to the list is not a bad thing. We know the OP sent to the list,
because his post appeared on the list :-)

The question is whether he BCCed a bunch of regulars or not.

Unfortunately I deleted the email so I can't look at the headers, but
nevertheless I can categorically say that it didn't come from the mailing
list, because the python-list@python.org mailing list doesn't have my
address. I've always read this though the newsgroup.

I do still have the relevant mail logs:

I'm not an expert, but to me that looks pretty convincing that the email
came directly from Google, not from the mailing list. Am I wrong?

Maybe you weren't one of the people he BCCed :-)

Judging from the question on Stackoverflow, I think he's just trying to
drive eyeballs to the question so he can get higher reputation. It is a
silly question: he says he has a pickle file containing an image file, and
he's asking (1) what's in the pickle file, and (2) how can he create an
identical pickle file containing a different image.

The answer to (1) is "Whatever you put in it".

Or possibly malware: he links to an actual pickle file he has put up on-line
somewhere. Anyone brave enough to unpickle it in a sandbox and report on
whether it contains what he says it contains? Remember that pickles can
contain arbitrary executable code.

I do not want to go into the details of your concrete problem --
just give some general remarks about "pickle".

"pickle" is used for serialization/deserialization of (most) Python objects:
i.e. it can transform a Python object into a string (called a "pickle")
and (later) reconstruct the object from the pickle.

You should not be interested in the internal pickle structure --
keep at the Python level.


For your concrete problem: unpickle your pickle file to get
a Python object; construct a similar Python object with the new data;
pickle that Python object.

Sorry for the multiple questions but my while loop is not working as intended.

Here is the code :
n = 1
list1 = []
count = 0  #amount of times program repeats
steps = 0 # amount of steps to reach 1
step_list = []
while n!=0:
n= int(input())
list1.append(n)

steps+=1
if num%2 == 1:
num=int(3*num+1)
print(num)
steps+=1

count+=1
step_list.append(steps)
steps=0

This code is meant to get numbers from the user in different lines and convert

Simple Python question for some

[Mark L. Hotz]

I have what I think should be a relatively simple question for someone who
is knowledgeable about Python.

 

At the IDLE prompt, when I enter b  99, it responds True. In fact, it
doesn't matter which number is entered here, b is always greater (e.g. b
 1 == True; b  10 == True, or b  99 = False).

 

Why is this true?  If I use ord(b) it returns 98, so Python cannot be
using the ASCII or Unicode value when interpreting b  99.  When I sort a
mixed list using Python, and the list contains b among a series of numeric
values, b is always sorted as last, indicating that it has a value greater
than the highest number?

 

How do I prove that b is greater than any number?  Or is it something very
simple, and Python simply orders characters after numbers, or perhaps Python
only interprets numbers like 99 as a 9 (i.e. ord(9) == 57)?

 

Thank you.

 I have what I think should be a relatively simple question for someone who
 is knowledgeable about Python.

 At the IDLE prompt, when I enter “b”  99, it responds True. In fact, it
 doesn’t matter which number is entered here, “b” is always greater (e.g. “b”
 1 == True; “b”  10 == True, or “b”  99 = False).

 Why is this true?

Per http://docs.python.org/2/library/stdtypes.html#comparisons :
Objects of different types, except different numeric types and
different string types, […] are ordered consistently but arbitrarily
(so that sorting a heterogeneous array yields a consistent result).
Note that the except part just means that, e.g. floats and ints can
be compared with each other, and Unicode and byte strings can be
compared with each other. It does NOT mean that numbers and strings
can be meaningfully compared with each other.

This is fixed in Python 3, where such nonsensical comparisons will
instead raise TypeError.

  If I use ord(“b”) it returns 98, so Python cannot be
 using the ASCII or Unicode value when interpreting “b”  99.

It has nothing to do with implicit casting between strings and numbers
(which, as a general rule, Python does not do).

From the same linked section as before:
CPython implementation detail: Objects of [incompatible types] are
ordered by their type names

So ints come before strs because int comes before str lexicographically.

To Python, different object types are completely different.
Incidentally, with issues like this, it's worth mentioning which
version of Python you're using - though in this case, it's clear
you're using Python 2. As of version 3, behaviour is different:

Python 3.2 (r32:88445, Feb 20 2011, 21:29:02) [MSC v.1500 32 bit
(Intel)] on win32
Type copyright, credits or license() for more information.
 b  99
Traceback (most recent call last):
  File pyshell#1, line 1, in module
b  99
TypeError: unorderable types: str()  int()


As of Python 2, there's a slightly esoteric rule as described here:
http://docs.python.org/2/library/stdtypes.html#comparisons
CPython implementation detail: Objects of different types except
numbers are ordered by their type names; objects of the same types
that don’t support proper comparison are ordered by their address.

So since str is greater than int, b is greater than 99.

Fortunately, Python does NOT have arcane rules for comparing numbers
as though they were strings. Notably:

 100 == 100
False

Which means that strings will ALWAYS be compared as strings, and
numbers will ALWAYS be compared as numbers, and ne'er the twain shall
conflict. I can trust Python to compare MD5 hashes reliably:

 912128034267498495410681495015e0 != 00912128034267498495410681495015
True

Of course, I'm not pointing fingers at any other languages here, but
this is a known security hole in one rather widely-used one.

It's worth pointing out that at least one kind of inequality comparison
which some people (e.g. me) would consider nonsensical is still allowed
in Python 3, which is between Boolean values and numbers:

   True  1
  False
   False  1
  True

which is probably because

   True == 1
  True
   False == 0
  True

Many people (probably most people, to be honest) disagree with me that
this is wrong, but regardless of whether you like it or not you need to
know what happens in such cases.

I'm clearly not understanding something about scope in python...  Any help

In the following script I'm attempting to create 2 Foo objects, for each Foo
object I create 2 Bars and add them to Foo's bar array

Something hokey is occurring with the foo.bars.append(bar) line such that
Foo.bars is treated as a static (I know python doesn't have statics)

I have a workaround using encapsulation for the bars array but I prefer

It's a pretty common gotcha for people coming from other languages.
Everything declared in the class scope becomes an attribute of the
class.
 class Foo(object) :
...a = 3
...def b() : pass
...
 dir(Foo)
['__class__', '__delattr__', '__dict__', '__doc__', '__format__', '__getattribut
e__', '__hash__', '__init__', '__module__', '__new__', '__reduce__', '__reduce_e
x__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', '_
_weakref__', 'a', 'b']

Mutating those objects mutates the attribute of the class, which is
visible to all instances of the class.

In order to get an instance of a class, you have to add the field to
the instance of the class instead of to the class itself.

class Bar(object) :
def ___init__(self) :
self.a = 3

You are sharing this single sub dictionary with all instances of your

If you want to define instance-specific attributes, define them in the
__init__ method, like so:

class A:
def __init__(self):
self.sub = dict()

Kristofer Tengström krille...@gmail.com writes:

That terminology is rather confused.

I think what you want is to have instances with their own attributes.

 class A:
 sub = dict()

This binds a single object (a new empty dict) to the class attribute
‘sub’. Every instance of class ‘A’ will share the same attribute, and
hence that same dict.

 def sub_add(self, cls):

This defines a function which will be bound to the class attribute
‘sub_add’. It will, when later called as a method, receive the instance
as the first parameter, bound to the local name ‘self’.

 obj = cls()
 self.sub[obj.id] = obj

Here, ‘self’ will be an instance of the ‘A’ class. Each instance has no
‘sub’ attribute, so Python will find the class attribute ‘A.sub’, shared
by all ‘A’ instances. You're then modifying that class attribute ‘A.sub’.

[…]

 Now, what I get from this is the following:
 __main__.B instance at 0x01FC20A8
 __main__.B instance at 0x01FC20A8
 Why is this?

I hope the above explains it.

 What I want is for them to be two separate objects, but it seems like
 they are the same one.

Yes. Anything you talk about in the class definition scope cannot know
about any instance of that class, since the instances don't exist yet.

Instead, instance attributes need to be bound to a particular instance,
which means you need to have a reference to the instance; that's what
‘self’ is for. The class initialiser is a method named ‘__init__’, and
is called on each newly-created instance before that instance is
returned from the constructor.

I advise you to work through the Python tutorial, beginning to end,
which will give you a good grounding in these and other fundamental
Python topics URL:http://docs.python.org/tutorial/. Work through each
example, understand it by experimenting, and then proceed to the next,
until you've done the lot.

Hi,
You are getting same object because you are overriding the dictionary
update.
Its printing the proper value with the last updated instance of B.

If you want to see the two different instances of class B give print
self.sub inside the sub_add method in class A.

What do you mean by accessing a hash element? Do you mean the hash of

Re: Python question

[DreiJane]

Hello,

Python and gtk are ambulant (portable plus intallable by mere
copying without admin rights). gtk only needs to have the path to its /
bin on the PATH . The latter could - and possibly should be - done by
the Python scripts using it, for example:

s = os.environ['PATH']
if s.find(gtkBinDir) == -1: os.putenv(PATH, os.getenv(PATH)+
os.pathsep + gtkBinDir)

for gtkBinDir from some GlobalConstants.py.

Pygtk breaks that ambulance - its parts use the registry, but only
for finding Python during installation. Afterwards such a Python is
ambulant again - that means with its pygtk (this little flaw is a
minor reason for me to work on my depikt). I am on Windows normally,
but never considered pywin.

Good luck, Joost

python-2.6.1.msi
pygobject-2.14.2-2.win32-py2.6.exe
pygtk-2.12.1-3.win32-py2.6.exe
pywin32-213.win32-py2.6.exe
gtk-2.12.9-win32-2.exe


You might estimate it by the size of those files; use a factor of 2 or 3  
due to compression.



Does all this packs requires installation,


python and gtx must be installed as any other Windows program, and  
probably require administrator rights. I don't know all of the remaining  
files, but they look like Python packages; the installer typically drop  
some files into c:\python26\lib\site-packages and register something.


or it's possible just extract and place them in to C: drive, then to set  
environment variables properly?

Does this packs installs dynamic libraries and writes to registry?


Python and Gtk, yes. The other packages, maybe not.

Its Linux.

The configure build does not say anything actually. This is for SAGE.
I managed to have it pick it up by compiling/installing tcl and tk and
then recompile python


Then most probably installing the tk-dev packages would have been 
sufficient.

This is mainly for matplotlib's TkAgg. It seems my compiled version of
python isn't finding the module _tkagg

 Well, I've never seen a snake program in any language,

 Anyway, why not tell you what you want to install, and on

    On web page:   http://www.python.org/download/, you'd choose Python

What are you trying to install?

is it available in Synaptic package manager?


If it's a program written in python, then there may be a file called
setup.py. If there is then open a terminal, cd to that directory, and
then type:

python setup.py install

(you may need to do sudo before it) - that will normally automatically
compile any extensions written in C

hope that helps.

I guess the shebang is simply ignored - the actual interpreter is

It's a bit weird that there is Python with a capital P, but what happens 
if you change that to Python2.5 for example?

Hi Diez,

Thanks for your reply.  I gave this a try too, but it doesn't seem to work 
either.

However, a gentleman just emailed me off-list recommending to use the full path 
to Python that is in /usr/local/bin.  This is where Python 2.5 looks to be 
installed rather than Python 2.3 which is in /usr/bin.  I ran the following 
code below and it works great!

 
 set p to #!/usr/bin/python
 import sys
 print sys.version[:3]
 set x to do shell script /usr/local/bin/python -c \  p  \
 return x
 

Thank you all again for your thoughts and replies.  I really appreciate it!!

Jay

Change the first line to

set p to #!/usr/bin/env python

That will execute the default python installation...assuming 2.5.2 is
the default.  Otherwise, you can change that to the absolute path of
the 2.5.2 version.

Hi Sean,

Thanks for your fast reply.  This still doesn't seem to work.  I also tried 
changing it to
#!/usr/local/bin/python since it looks like the Python 2.5 items are actually 
in there.  I'm starting
to wonder if AppleScript's 'do shell script' command is actually looking in 
/usr/bin for Python by
default?

Thanks.
