A really basic tkinter question

[P_Monty]

Hi,
This probably is really basic, but here goes...
I'm trying to learn python by reading books and checking online resources and doing OK so far. My next step is to put a small graphical wrapper around what I'm doing.
So far, I've got this:

Code: Select all

#!/usr/bin/env python

#Import anything necessary
from tkinter import *

#define some functions
def OKaction():
        print('Pressed OK')
def Quitaction():
        print('Pressed Quit')

window = Tk()
window.title("Control Panel")
buttonOK=Button(window, text="OK", command = OKaction)
buttonOK.pack()
buttonQuit=Button(window, text="Quit", command = Quitaction)
buttonQuit.pack()



mainloop()

I'm editing this in an IDLE3 window. If I hit 'run' from the window, the code behaves as expected. If I bring up a text terminal and type 'python filename.py' I get an error that there's no module called tkinter.

can someone tell me what's happening and how toi fix it so I can run my code from the command line?

Thanks

Paul

You're using python3 in IDLE3, but Python 2 on the command line. In python 2 the module name is Tkinter.
It's best to stick to one version, so I would use

Code: Select all

python3 filename.py

That was quick and easy - thanks
I was wondering if it was something like that, but couldn't find a way of telling what version of python I was using on the command line.

Too late for you, but for the next person who might need to know

Code: Select all

pi@RPi2B ~ $ python --version
Python 2.7.3

or simply

Code: Select all

pi@RPi2B ~ $ python
