Which is better for a beginner to get started in Python with? Thanks! -- http://mail.python.org/mailman/listinfo/python-list
Re: Python 2.7 or 3.1
Would it be safe to say that 2.6 would be even better for beginners than? -- http://mail.python.org/mailman/listinfo/python-list
Create a GUI and EXE for a python app?
Having trouble with my mail client, so sorry if this goes through more than once. I'm worknig on a simple math program as my first application. I would like to make a cross-platform pretty GUI for it and also package it up in a EXE for distribution on Windows. What are the best and easiest ways I can do this?Thanks! -- http://mail.python.org/mailman/listinfo/python-list
RE: Python 2.7 or 3.1
I personally would take only one bite at a time. Meaning only do one then do the other later.

RE: text file reformatting
Sorry to clarify, I was having issues getting this to work. I'm relatively new
to Python. Sorry for the miscommunication.

[Beginer Question] I heard about python needing some sort of _VariableName_ boiler plate?
Can anyone explain to me how this works, I don't seem to have to do it in IDLE? Thanks! -- http://mail.python.org/mailman/listinfo/python-list
Best method for a menu in a command line program?
I'm using a menu for my command line app using this method.
choice = "foobar"
while choice != "q":
if choice == "c":
temp = input("Celsius temperature:")
print "Fahrenheit:",celsius_to_fahrenheit(temp)
elif choice == "f":
temp = input("Fahrenheit temperature:")
print "Celsius:",fahrenheit_to_celsius(temp)
elif choice != "q":
print_options()
choice = raw_input("option:")
Just wondering if there is another or more efficient way I should be doing it?
Thanks

Sorry, I wasn't aware it was doing that but... I've removed it :-) Sorry about that, Braden Faulkner -- http://mail.python.org/mailman/listinfo/python-list
