Gmail has a "Show original" link in the message drop-down menu. But in
this case I just searched the September text archive:

https://mail.python.org/pipermail/tutor/2013-September.txt

I replied to you using Gmail's "Reply to all" in the webmail
interface, which added "In-Reply-To" and "References" to the header.

RFC 2822:
http://www.ietf.org/rfc/rfc2822.txt

   The "In-Reply-To:" and "References:" fields are used when creating a
   reply to a message.  They hold the message identifier of the original
   message and the message identifiers of other messages (for example,
   in the case of a reply to a message which was itself a reply).  The
   "In-Reply-To:" field may be used to identify the message (or
   messages) to which the new message is a reply, while the
   "References:" field may be used to identify a "thread" of
   conversation.

   When creating a reply to a message, the "In-Reply-To:" and
   "References:" fields of the resultant message are constructed as
   follows:

   The "In-Reply-To:" field will contain the contents of the "Message-
   ID:" field of the message to which this one is a reply (the "parent
   message").  If there is more than one parent message, then the "In-
   Reply-To:" field will contain the contents of all of the parents'
   "Message-ID:" fields.  If there is no "Message-ID:" field in any of
   the parent messages, then the new message will have no "In-Reply-To:"
   field.

   The "References:" field will contain the contents of the parent's
   "References:" field (if any) followed by the contents of the parent's
   "Message-ID:" field (if any).  If the parent message does not contain
   a "References:" field but does have an "In-Reply-To:" field
   containing a single message identifier, then the "References:" field
   will contain the contents of the parent's "In-Reply-To:" field
   followed by the contents of the parent's "Message-ID:" field (if
   any).  If the parent has none of the "References:", "In-Reply-To:",
   or "Message-ID:" fields, then the new message will have no
   "References:" field.

   Note: Some implementations parse the "References:" field to display
   the "thread of the discussion".  These implementations assume that
   each new message is a reply to a single parent and hence that they
   can walk backwards through the "References:" field to find the parent
   of each message listed there.  Therefore, trying to form a
   "References:" field for a reply that has multiple parents is
   discouraged and how to do so is not defined in this document.

Clearly gmail isn't showing you all the headers.  I looked for Alan's
message in one of these threads with the same subject, and see about 60
lines of header information.  Does gmail have a View->Source menu item?

I use gmail and just use the "funny" looking arrow at the top that
says "reply" and I can see that in the news.gmane.org feed my mail is
sorted nicely in the response section but it isn't on either
code.activestate or on mail.python.org as eryksun stated as well.
I just want to be able to make my responses easily visible in most of
the online archives since otherwise they don't make sense for anyone
not subscribed to the daily mailing list.

You need to write the data to a file or database when the program closes 
and then, when you start the program, read the data from

that file or database.


Here's the code I wrote so far:


OK, This is very basic and can be improved in lots of ways so I'm 
guessing you are a new programmer and studying via some kind of

course or tutorial?

At some stage it will cover reading and writing to files as well as data 
structures that will help store your data more effectively and looping 
constructs that will help you process it more effectively.


You can read up on reading and writing to files if you want but
it may be better not to run before you can walk...


print("This is my to do list")

Monday = input("Monday ")
Tuesday = input("Tuesday ")
Wednesday = input("Wednesday ")
Thursday = input("Thursday ")
Friday = input("Friday ")
Saturday = input("Saturday ")
Sunday = input("Sunday ")

"\nFriday " + Friday +

Hi,

Docopt is an alternative to optparse and argparse. Incredibly cool, and fun

To have data still available next time you run the program, you need to
write it to a file.

outfile = open("statefile.txt", "w")
outfile.write("Monday")
outfile.close()

Naturally, if you store non-trivial data, you'll have to organize it
somehow, so you can parse it when you read it back in.

Alternatively, you can use a module like configparser:

http://docs.python.org/3.3/library/configparser.html#module-configparser

or several other alternatives.

I just wanted to get rid of Python 3.2 as I thought it had no purpose.
Maybe I also could have done apt-get install --only-upgrade python3.
apt-get update does not update python 3.2 to 3.3.

Thanks. I will use that from now on. Much better indeed. But isn't it safer to 
also specify the minor python version?

Hej there,

I want to write a simple program (To Do List) that stores the input

print("This is my to do list")

Monday = input("Monday ")

Talking about anonymizing, this is legal:

#!/usr/bin/python
# -*- coding: rot13 -*-qrs fbzrShap(*netf, **xjnetf):
   cnff


...because:

>>> print """qrs fbzrShap(*netf, **xjnetf):
    cnff""".decode("rot13")
def someFunc(*args, **kwargs):
    pass

fun, isn't it?

Thanks for the suggestions and sorry about the errors when I tried to anonymize 
my code. It's turns out when I ran the code through setup, I had an __init__.py 
file incorrectly defined which generated the error. The error from the 
traceback was at the line where I was importing the module. I have it working 
now.

Hmm, I think you are incorrect. The try/except logic is used
when there is not row[1] in the dictionary (i.e. every first
entry of a key). I guess that handles multiple keys, but it 
would be clearer if you used the setdefault method on the 
dictionary.

Dict1.setdefault( row[1], [] ).append( row[0] )

Unless you have a non-standard environment (at least not 
one I am familiar with), you do not need setup tools as long
as the script is somewhere on the PYTHONPATH. Also, the
dictionaries are not created except on first import of the 
module (at run-time not compile-time). 

If they are static or mostly so, you may want to just hard code 
them in the myDict module (lowercase for module names is 
the community standard) for easier modification. In addition,
that means you can get rid of the source files file1 and file2.

You can use `print repr(Dict1)` to copy paste the 
dictionaries into the code.

The import and the error do not seem to match. Can you
please copy/paste (do not paraphrase or try to retype)
the FULL error?

I can't answer for some third-party archive of the list.  But your
message on the current mailing list doesn't seem to be a reply to any
existing one.  I'm viewing the list through the news.gmane.org feed, and
it is happy to thread messages and their responses nicely, regardless of
subject line.

How did you respond to the earlier message?  Did you just compose a new
one and address it to the mailing list?

In-Reply-To: <1379734001.35687.yahoomail...@web184701.mail.ne1.yahoo.com>

Your message's header doesn't have this field:

I guess it does seem harsh but it's definitely true. Albert-Jan still
hasn't explained what he was trying to achieve with that command but I
stand by my claim that whatever it was can be achieved in a better and
safer way.

If you try 'sudo apt-get remove python3'  then apt will check the
database of installed packages to see if anything depends on the
python3 package. If nothing depends on it then it will be safely
removed and the apt database will be updated to reflect the fact that
it is no longer installed. Otherwise it will report the full list of
packages that would also need to be removed because they depend on
python3 and ask if you want to remove all of them. At this point
you'll probably think "What on earth are all those packages? Maybe I
need them." and then answer no.

On the other hand 'sudo rm -rf /some/system/dir' will check nothing
and will simply remove the files. The combination of sudo and the -f
flag means "I know what I'm doing so shut up and do what I say". I
rarely feel confident enough to do that and I can't think of the last
time I had a reason to do it.

I regularly use 'rm -rf' because that's needed to delete e.g. a git
repository which contains a whole load of files marked as read-only.
Without the -f you'll have to answer 'y' thousands of times. But I
don't usually have git repositories that are owned by root so I don't
need the sudo part (I have sometimes used git to manage system files
like fstab, grub etc.).

Re: [Tutor] HELP Please!!!....How Do I Make a Graph Chart Generate in Python Based on my Code

[Dino Bektešević]

Hello,

I wrote a response on the subject in the title about creating a graph
in Python using the Graphics module presented in the standard python
tutorial on 23rd detailing full explanations but I still saw repeated
responses asking more of the same question (lines causing the error,
which graphics module are you referring to etc...) which is ok because
I don't mind multiple answers to the question, not everything usually
gets covered in only one and it's a check up if I answered something
wrong.

But it still kind of bothered me that so many of same questions got
repeated so I googled to see the archives and it seems my response was
not placed in the same archive "thread" as it should have been, and
doesn't appear in the response list of the question.

original question: http://code.activestate.com/lists/python-tutor/96889/
my response: http://code.activestate.com/lists/python-tutor/96897/

For someone browsing through Tutor in archive form I can see how this
is a tad confusing, is it fixable? I'm guessing that my mail wasn't
put in the response list because of different titles?

Regards,
Dino
