This is what it looks like over here:

This is what I suppose you wrote:

> chr = 0
> while chr != 'q':
>     print "my code",

You could make a little experiment. Run

import msvcrt
while True:
    if msvcrt.kbhit():
        print msvcrt.getch()

and then press the 'q' key. What does this little script print? Can you 
apply the newly gained information to your original code?
