A question about IDLE and environment variables
Hello community: I post this because I could not find satisfactory answers in the posts generated by this nice group. I work on winXP. I have many little python applications in different folders, each application can share or not other objects located in the same or other folders. The way I work to use these applications is: 1) For almost everyone, I execute a corresponding ".bat file" into which I define and/or include values for some "temporal" environment variables that let me find all the objects that the selected application uses. Sometimes I include in the .bat file the execution of the application, but generally I leave in a prompt status, ready to invoke python or some dos commands. 2) When I close the command prompt window, there are no traces of my enviroment variables in my windows system (that is right). Only the default windows environment variables remain. I tried to do the same with the IDLE (and I imagine tha same occurs with Python command line), but I have the next problem: I can not find in IDLE (or another app?) the way to previously define and/or include automatically values for my "temporal" environment variables as I do in the .bat files. The use of Control Panel -> System -> Advanced is tedious to use as, my enviroment variables values are "temporal". Any advice, please??? -- http://mail.python.org/mailman/listinfo/python-list

When you run code from an edit window, IDLE saves the file to disk and then *imports* it into the shell window. If you *paste* code into the shell window (regardless of where from), then it acts like you typed it and you will get expression results echoed, as you expected. I got caught be this at first too, since I have run many snippets by pasting. Terry Jan Reedy -- http://mail.python.org/mailman/listinfo/python-list

Thank you! I can see only your reply. But indeed google prints three. The mind boggles.

In a module it doesn't do that, as then you'd have all sorts of things printed out modules were imported. -- http://mail.python.org/mailman/listinfo/python-list

You never gave it any commands that print output. I suggest reading the Python tutorial. Sybren -- The problem with the world is stupidity. Not saying there should be a capital punishment for stupidity, but why don't we just take the safety labels off of everything and let the problem solve itself?

while the interactive console echoes the result back if you type in an
arbitrary expression, the interpreter doesn't do that if you run things in
a script.
to print stuff from a script, use the "print" statement.
print now
print now.strftime(...)
...
print age.days
your favourite tutorial (hopefully) contains more information about the
interactive mode, and how it differs from code in scripts or modules.
hope this helps!

About IDLE?
Installed Python 2.4.2 on Windows XP.
Activated IDLE.
Loaded the following into the Edit window:
---
# dates are easily constructed and formatted (Tutorial 10.8)
from datetime import date
now = date.today()
now
now.strftime("%m-%d-%y. %d %b %Y is a %A on the %d day of %B.")
# dates support calendar arithmetic
birthday = date(1985, 12, 1)
age = now - birthday
age.days
---
When I select Run Module in the Edit window, I got only
two >>> after the RESTART line.
I expected to see the output of several commands!
Typing in age.days do produce the number of days.
Why I do not get any output?
Thanks for any guidance.
