SMTP-Email Help

somehow the program is unable to send email.

I believe that Google has locked you out of your account.

Are you aware that you've just made your username and password visible to 
the entire Internet? If you hadn't already triggered Google's anti-spam 
detection, you surely have now.


 gmail_user = @gmail.com
 gmail_pwd = **

(details redacted, to shut the barn door now that the horse has already 
run away)


When I log into your gmail account with those credentials, I see:



Verify your account

We've detected unusual activity on your account. To immediately
restore access to your account, choose how to verify your account.



so I believe Google have locked the account because they think you're 
spamming. You'll need to fix that before anything else.

Right, the only API change between 0.6 and 0.9 is the removal of the 
'pickleable' parameter to open_workbook. However, this was removed 
because it hadn't worked in a long long time.



   Both Fedora and CentOS has python=2.6, python3 is available for Fedora
too (no plans to release python3-xlrd now).


xlrd 0.9 and above works with both python2 and python3 as-is.


   So can I release an update for all my Linux distributions with backward
compatibility of this package? xlrd-0.8 was requested for xlsx support.


I would suggest just going for 0.9.2.


   Are there some howtos describing upgrading applications using xlrd
to newer versions? These documents can help me to choose, if I can release
an update.


There aren't any, because there are no changes. Applications written for 
0.6.x will still work without change when using 0.9.2.

How do I encode and decode this data to write to a file?

[cl]

I am debugging some code that creates a static HTML gallery from a
directory hierarchy full of images. It's this package:-
https://pypi.python.org/pypi/Gallery2.py/2.0


It's basically working and does pretty much what I want so I'm happy to
put some effort into it and fix things.

The problem I'm currently chasing is that it can't cope with directory
names that have accented characters in them, it fails when it tries to
write the HTML that creates the page with the thumbnails on.

The code that's failing is:-

raw = os.path.join(directory, self.getNameNoExtension()) + .html
file = open(raw, w)
file.write(.join(html).encode('utf-8'))
file.close()

The variable html is a list containing the lines of HTML to write to the
file.  It fails when it contains accented characters (an é in this
case).  Here's the traceback:-

Traceback (most recent call last):
  File /usr/local/lib/python2.7/dist-packages/gallery/galleries.py, line 41,

in createPictureHTML file.write(.join(html).encode('utf-8')) 
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 783:

If I understand correctly the encode() is saying that it can't
understand the data in the html because there's a character 0xc3 in it.
I *think* this means that the é is encoded in UTF-8 already in the
incoming data stream (should be as my system is wholly UTF-8 as far as I
know and I created the directory name).

So how do I change the code so I don't get the error?  Do I just
decode() the data first and then encode() it?

You can verify that your filesystem is set to use UTF-8 with 
sys.getfilesystemencoding(). If it returns 'ascii', then your locale settings
are incorrect.

Good Afternoon,

Among other elements values that my script finds is value for sepid

sepid = content.find(.//{http://www.huawei.com.cn/schema/common/v2_1}sepid
).text


however, if i pass xml data that DOES NOT contain sepid element, i get an
error:

Traceback (most recent call last):

Drag and drop in Windows

[Robert Flintham]

Hello all,

Sorry to post such a generic question, but after searching the interwebs I'm 
not really any wiser about how to start with this.

I'm currently on:
Windows XP
Python 2.7

I'm trying to create a small window in Python 2.7, that when you drop a file 
onto it from Windows explorer returns the file's path so that I can then go on 
to open the file and do whatever with it.  I was planning on using Tkinter 
because that's what I've used before for GUI's, but I can be swayed from this 
if needs be.

I've found this (TkDND):
http://wiki.tcl.tk/2768

But I don't know how to implement this in Python.  The Windows binary for it 
comes as a set of .tcl files and a single .dll file.

The two options I've stumbled across seem to be

1.  a Python wrapper for the DLL (I think to wrap C code??), which can then be 
imported like you'd import a Python package

2.  direct implementation of the Tcl file [tk.eval('source ...')], but I don't 
reallu understand what's going on with this - can you only execute a main bit 
of Tcl files rather than implementing individual functions?

Any input (however minimal) is definitely appreciated!  I've included what I 
think are probably the relevant functions from the Tcl files at the bottom of 
the email, but I don't really understand the nuts and bolts of the code.

All the best,
Rob

Note that you are getting a *UnicodeDecodeError*, not a UnicodeEncodeError. 
Try omitting the encode() step, i. e. instead of

 file.write(.join(html).encode('utf-8'))

use

file.write(join(html))

Background (applies to Python 2 only): the str type deals with bytes, not 
code points. The right thing to do is to use .decode(...) to convert from 
str to unicode and .encode(...) to convert from unicode to str. In Python 2 
however the str type has an encode(...) method which is basically equivalent 
to

class str:
   # imaginary python implementation of python2's str
   ...
   def encode(self, encoding):
   return self.decode(ascii).encode(encoding)

and is almost never called intentionally.

PS Python3 has relabeled unicode to str and thus uses unicode by default. 
str was renamed to bytes and the annoying bytes.encode() method is gone.

Please mention your Python version  OS.  Apparently you're running 2.7 
on Linux or similar.

You can't encode byte data, it's already encoded. So you're forcing the 
Python system to implicitly decode it (using ASCII codec) before letting 
you encode it to utf-8.  If you think it's already in utf-8, then omit 
the encode() call there.


Additionally, you can debug things with some simple print statements, at 
least if you decompose your 3-function line so you can get at the 
intermediate data.  Split the line into three parts;

temp1 = .join(html) #temp1 is byte data
temp2 = temp1.decode()#temp2 is unicode data
temp3 = temp2.encode(utf-8)  #temp3 is byte data again
file.write(temp3)

Now, you'll presumably get the error on the second line, so examine the 
bytes around byte 783.  Make sure it's really in utf-8, and if it is, 
then skip the decode and the encode.  If it's not, then Andrew's advice 
is pertinent.


I would also look at the variable html.  It's a list, but what are the 
types of the elements in it?



 file.close()

exception thrown. I deal with these annoyances like this:

sepelem = content.find(.//{http://www.huawei.com.cn/schema/common/v2_1}sepid;)
if sepelem is not None:
   sepid = sepid.text
else:

 You can verify that your filesystem is set to use UTF-8 with

 If it returns 'ascii', then your locale settings

 Please mention your Python version  OS.  Apparently you're running 2.7 
 on Linux or similar.
 
Sorry, yes you're spot on.


  I am debugging some code that creates a static HTML gallery from a
  directory hierarchy full of images. It's this package:-
   https://pypi.python.org/pypi/Gallery2.py/2.0
 
 
  It's basically working and does pretty much what I want so I'm happy to
  put some effort into it and fix things.
 
  The problem I'm currently chasing is that it can't cope with directory
  names that have accented characters in them, it fails when it tries to
  write the HTML that creates the page with the thumbnails on.
 
  The code that's failing is:-
 
   raw = os.path.join(directory, self.getNameNoExtension()) + .html
   file = open(raw, w)
   file.write(.join(html).encode('utf-8'))
 
 You can't encode byte data, it's already encoded. So you're forcing the 
 Python system to implicitly decode it (using ASCII codec) before letting 
 you encode it to utf-8.  If you think it's already in utf-8, then omit 
 the encode() call there.
 
It's the way the code was as I installed it from pypi.  What you say
makes a lot of sense though, I'll remove the encode().


 Additionally, you can debug things with some simple print statements, at 
 least if you decompose your 3-function line so you can get at the 
 intermediate data.  Split the line into three parts;
  temp1 = .join(html) #temp1 is byte data
  temp2 = temp1.decode()#temp2 is unicode data
  temp3 = temp2.encode(utf-8)  #temp3 is byte data again
  file.write(temp3)
 
OK, thanks for this and all the other advice on this thread.

According to wikipedia http://en.wikipedia.org/wiki/BMP_file_format


The size of each row is rounded up to a multiple of 4 bytes [...]


So 48/8 == 6 will be rounded to 8, and 8*48 == 384 == 0x180.

 handle1=open( bmpfilename ,rb)
 raw = bytearray(handle1.read( ))
 handle1.close

To actually do something the last line should be handle1.close(). I 
recommend

with open(bmpfilename ,rb) as handle1:
raw = bytearray(handle1.read())

instead which has the additional advantage that the file will be closed if 
an exception occurs in the with-suite.

[snip]
What size is 0x180?

If you're asking why the file size is 0x180 and not 0x120, it's simply
because of the header. An image file contains not just the pixels of
the image, but also information about the image.

Let's suppose it was. What would that mean?

Look inside mod1, where there might be a function spam(), and also 
another function eggs(). spam() calls eggs(), it sees the eggs function 
in the same module, and all is well with the world.

Then you add to the startup file:

def eggs():
return Something unexpected


and all of a sudden mod1.spam() breaks, because it now sees *your* eggs() 
instead of its eggs. This would be a bad, bad thing.

This is why modules are their own namespace, and the interactive 
interpreter is its own, independent, namespace. What happens in the 
interactive interpreter stays in the interactive interpreter, without 
stomping all over every other module.

The point of the startup file is to add things to the interactive 
interpreter's module, not to inject things into every module in sight.

The startup file is only for interactive use.  Python programs in files 
shouldn't depend on a startup file, as it will limit their portability.  
In an interactive session, it's helpful to save some typing, but you can 
use explicit imports in programs, as they only need to be typed once, 
and will be used many more times.

Yes, you need a separate import from any module that references numpy. 
Don't worry about performance, subsequent imports do not take noticeable 
time, since the module objects are cached.


Any time you want to use a symbol from another module, you have to get 
it somehow. into your own module.  You do not have to get it from the 
import statement, but it's certainly the simplest way, and the way 
that's usually clearest.


Each module represents a namespace, and except for the global namespace 
which is handled specially, you have to describe which ones you want 
access to.  It's a feature, not a limitation.


There are lots of modules automatically imported indirectly by the ones 
you use.  A quick test on a local copy of Python 3.3 shows 51 modules 
imported before I write any code.  I certainly wouldn't want all of them 
visible in my script's namespace.


 -- but then what is the point of having a startup file?


Presumably by startup file, you mean script.  Without a script, Python 
wouldn't have any idea what code to run.  You import a few modules, use 
functionality from them, and lots of things happen behind the scenes. 
Fortunately for all of us, Python doesn't throw all the symbols into one 
big pile.

Re: Drag and drop in Windows

[Christian Gollwitzer]

Hi Robert,

Am 29.04.13 12:25, schrieb Robert Flintham:

I’ve found this (TkDND):

http://wiki.tcl.tk/2768

 But I don’t know how to implement this in Python.  The Windows binary
 for it comes as a set of “.tcl” files and a single “.dll” file.
 2.direct implementation of the Tcl file [tk.eval(‘source …’)], but I
 don’t reallu understand what’s going on with this – can you only execute
 a “main” bit of Tcl files rather than implementing individual functions?

I can only comment on the Tcl side, since I'm not an expert in the 
Tkinter coupling mechanism. TkDND is indeed the way to go if you want 
native drag'n'drop support. The first step would indeed be to load the 
package into the Tcl interpreter. You need to:


1) Create a folder for the packages, put the files in a subfolder
Typically, this is something like lib/tkdnd, and at that level there 
must be the pkgIndex.tcl file

2) Append the lib/ folder to the auto path
tk.eval('lappend auto_path {mypath/lib}')
(the braces are Tcl's quoting mechanism)
3) load the package
tk.eval('package require tkdnd')

Then, you need to register the target, i.e. declare a widget that it 
accepts files. Here, you need the Tk path name of the widget, which is 
retrieved by __str__:


tk.eval('tkdnd::drop_target register ' + yourwidget +' *')

Then, if you drop something, the widget recieves a virtual event 
Drop:DND_Files . Now this is tricky, I don't know how to bind to 
that event. Following the tutorial for Tcl on http://wiki.tcl.tk/36708, 
I suppose something like


yourwidget.bind(Drop::DND_Files, filesdropped)

should in principle work, but how to get the data out of it? It is 
stuffed into the %D bind substitution. Usual events store the MouseWheel 
distance in this field; so maybe you can get it from the field 
event.delta. I can't test it now, but I am a bit skeptical whether this 
works with the guts of TkInter. If not, you'd need to do some more 
forwarding from the Tcl side.

I can fix this by including import numpy as np in any module that uses numpy
functions -- but then what is the point of having a startup file?


That fix is indeed the way things are done.  Modules only know about what 
they import or create*.

The point of the startup file is to have things ready for interactive investigation -- if you use numpy *alot* then 
having it already there beats the heck out of typing `import numpy as np` every time you start the interpreter.

I don't know what you mean by your clause, and I think we have a

Generiric advice for anyone getting unicode errors:
unpack the composition producing the error
so that one can see which operation produced it.

In this case
s = .join(html)\
s = s.encode('utf-8')
file.write(s)

This also makes it possible to print intermediate results.
  print(type(s), s)  # would have been useful
Doing so would have immediately shown that in this case the error was 
the encode operation, because s was already bytes.
For many other posts, the error with the same type of message has been 
the print or write operation, do to output encoding issues, but that was 
not the case here.

repeat program

time.sleep(1)

Turn it into a function call, and call that function twice from 
top-level.  Or, more generally,




for i in range(2):
doit()




import random
import time

def intro():
 print('You spot 2 caves in the distance.')
 print ('You near 2 cave entrances..')
 time.sleep(1)
 print('You proceed even nearer...')
 time.sleep(1)

def choosecave():
 cave=''
 while cave!='1' and cave !='2':

 cave=input()
 return cave

def checkcave(chosencave):
 friendlycave=random.randint(1,2)
 if chosencave==str(friendlycave):
 print ('you win')
 else:
 print('you lose')

playagain='yes'
while playagain=='yes':
 intro()
 cavenumber=choosecave()
 checkcave(cavenumber)

Replace the 'while' loop with a 'for' loop that loops twice.

By the way, there's a bug in 'choosecave': what happens if the user
enters, say, '3'?

You change something in the folowing two lines:

playagain='yes'
while playagain=='yes':

What you change and how you change it is probably your homework task, so 
I really shouldn't tell you any more than that.

No clue whom you think you're replying to, but all your replies so far 
are appearing in the thread as replies to your OP.  Please use a little 
context from the message you think you're responding to, so we have an 
idea what you're talking about.


Did you ever see MRAB's message, where he told you exactly what the 
change requested was?



if __name__ == __main__:
# This part will be run if the file is run as the main script.
#
# The multiprocessing module will import this file to run the
# player function, but __name__ won't be __main__ when it does
# so, therefore this bit of code won't be run.

#Initialisation
fenetre = Tk()
frame = Frame(fenetre, width=200, height=100)
instance = 'Instance'

#TK
frame.focus_set()
frame.bind(Key, key)
frame.pack()
fenetre.mainloop()

All of those lines were at the left margin in your earlier posted code, 
and you give us no reason to expect you've made them conditional.

[issue16142] ArgumentParser inconsistent with parse_known_args

[paul j3]

paul j3 added the comment:

Correction: The patch I gave in the last message produces:

 parser.parse_known_args(['-ku'])
(Namespace(known=False), ['u'])

It doesn't take action on the '-k', and puts 'u' in extras, not '-u'.

This new patch gets it right:

 parser.parse_known_args(['-ku'])
(Namespace(known=True), ['-u'])

We need more test cases, including ones that work as expected with optparse or 
other unix parsers.

[issue17865] PowerPC exponentiation and round() interaction

[Mark Dickinson]

Mark Dickinson added the comment:

Hmm:  it's not an obvious Python bug, either:  both math.exp and math.ceil are 
simple wrappers around the libm functions, so there's little room for things to 
go wrong between Python and the OS.

Are you in a position to compile Python from source on your platform?

What was the equivalent C program you tried?  What's the compiler on this 
platform?  Note that gcc (I believe) evaluates math function calls for 
constants at compile time (using MPFR), rather than run time, which would mean 
if your C program simply does exp(-2.0); then it's not even using the OS libm.

 Ned Deily added the comment:
 
 That's really odd.  It looks you have a permissions problem with your home 
 directory. On startup, IDLE attempts to create the directory .idlerc in your 
 home directory, /Users/ben, if it doesn't exist already.  If for some reason 
 the directory creation fails, IDLE aborts.  Interestingly, if the directory 
 exists but IDLE lacks write permission to create files in it, it does not 
 abort but posts a warning message in a window.  Perhaps it could be a little 
 more consistent about that.  But still, this appears to be avery unusual 
 situation.  I can't think of any reason why IDLE would be unable to create a 
 directory unless you have some security system installed or some unusual 
 access control list setting.  The most likely reason is just a plain old 
 permission problem on your home directory.  Try this in a terminal session:
 
 cd ~
 ls -lde ~
 
 You should see something similar to this:
 drwxr-xr-x+ 38 nad  staff  2992 Apr 28 15:26 /Users/nad/
 0: group:everyone deny delete
 
 if the permissions string is missing the w (dr-xr-x), that means you do 
 not have write permission to your home directory and can't create new 
 directories there.  In that case, 
 
 mkdir ~/.idlerc
 
 should fail.  (This is essentially what IDLE is trying to do.)
 
 If you are missing write permission on your home directory, you *should* be 
 able to fix it by doing:
 
 chmod u+w ~

[issue17866] TestCase.assertItemsEqual exists in 2.7, not in 3.3

[Ezio Melotti]

Ezio Melotti added the comment:

I don't remember how it went exactly, but there were a few similar methods 
(assertItemsEqual, assertSameElements, assertCountEqual).  In 3.x we eventually 
decide to remove the first 2 because it wasn't clear what they were doing, and 
only assertCountEqual survived.  In 2.7 this wasn't possible, so 
assertItemsEqual survived.
assertDictContainsSubset is another method that was in 2.7 but is not in 3.x 
anymore.
Do you think the docs for 2.x should mention this?

[issue17866] TestCase.assertItemsEqual exists in 2.7, not in 3.3

[Ronald Oussoren]

Ronald Oussoren added the comment:

I do think this should be mentioned in the 2.7 docs, assertDictContainsSubset 
is mentioned as deprecated since 3.2 in the 2.7 docs.  The only problem with 
that is that there doesn't seem to be a versionremoved directive in sphinx, 
the best alternative seems to be deprecated-removed.

I'm not to happy about the removal though, assertCountEqual is not in 2.7 which 
means it is unnecessarily hard to port tests from 2.7 to 3.3. I also don't 
quite understand the difference between assertCountEqual and assetItemsEqual, 
the documentation for the two (in the 3.3 and 2.7 docs) appears to indicate 
they have the same behavior (both assert that two sequence have the same 
contents when the order of items is ignored).

You're right, according to #10242 the method was renamed in 3.2.

Something like the attached patch?


I'm somewhat flabbergasted that #10242 came to the conclusion that it would be 
a good idea to rename this method, given the folks that contributed the 
discussion.   It not that the new name is very good, I've seen it in the 3.3 
docs and didn't notice that it was relevant for what I was trying to do until 
you mentioned the method and I actually read the description. When I first saw 
the method I thought it was related to list.count.

[Ezio Melotti]

Ezio Melotti added the comment:

Apparently assertItemsEqual was added to 2.7 and 3.2 and, after the release of 
2.7 but before the release of 3.2, assertItemsEqual has been renamed 
assertCountEqual (596239da3db7) and initially the assertItemsEqual was 
available too.  However, since the method was new in 3.2 the old alias got 
removed shortly after (bdd57841f5e2).  Eventually 3.2 was released with only 
assertCountEqual.

Looks like we wrote a similar patch at the same time :)
We don't usually use versionchanged in the 2.x docs for things that changed in 
3.x.  Using named instead of renamed is better, since in 3.x the name was 
assertCountEqual since the beginning, however saying In Python 3.2 might be 
confusing (people might think that it's different for 3.3+).  I suggest to 
replace it with simply Python 3, or perhaps Python 3.2+.

[issue17864] IDLE won't run

[Ned Deily]

Ned Deily added the comment:

The ls shows that, for some reason, your home directory is owned by user 
temp, not by user ben. That's not good.  Try doing this:

sudo chown ben /Users/ben/

But we're way past an IDLE or Python problem here.  This is a basic Unix system 
administration issue.

[issue17851] Grammar errors in threading.Lock documentation

[Ramchandra Apte]

Ramchandra Apte added the comment:

I'm saying that they aren't valid grammar mistakes (there is no grammar
mistake). I agree with Georg Brandl's comment.

 Andriy Mysyk added the comment:

 Ramachandra, if I understand you correctly, I think what you are saying
 that both are grammar mistakes and the first one could addressed by adding
 s to block.

[issue17834] Add Heap (and DynamicHeap) classes to heapq module

[Raymond Hettinger]

Raymond Hettinger added the comment:

Daniel, I've already been in the process of adding a class to the heapq module 
and have done substantial work on it over the last few months.  I'll look at 
your code to see if there are any ideas that should be merged with it before I 
finish it up.

Am attaching my current draft for Heap().  A PriorityQueue() variant would also 
be added to 3.4.

[issue17673] add `copy_from` argument to temporaryfile

[Kyle Roberts]

Kyle Roberts added the comment:

Thanks for the comments Antoine. I didn't have a good reason for using the file 
name at the time, although even when using the file name I should have used the 
file variable that was already created. I tried using the file descriptor, 
but I encountered a [Errno 9] Bad file descriptor once the methods using 
_mkstemp_inner call _io.open on the returned fd. This leads me to believe that 
the fd is being closed somehow, but as you can see from my copy function, I 
don't implicitly or explicitly close the file using the file descriptor. I'm 
not sure yet why the file name works as expected but the fd does not. Am I 
missing something simple?

As for points 2-4 I have most of that done. What's the pythonic way for 
determining if an argument is file-like? I've seen isinstance, hasattr, etc.
