[Tutor] msvcrt.getch() (original) (raw)

Hello all,

I was trying to set up a 'press any key to exit' mini-program similar to the one described here: http://www.freenetpages.co.uk/hp/alan.gauld/tutor2/tutevent.htm, but there seemse to be an issue with msvcrt.getch() on my computer (Windows XP Home, Python Version 2.3.4 final, IDLE version 1.0.3) when I ran it on IDLE. When I just type [msvcrt.getch()] at the prompt, it returns '\xff' as shown below:

msvcrt.getch() '\xff'

This means that when I try running the script described at the above website, a space does squat, as demonstrated below:

Hit space to end...

255 255 255 255 255 255 255 255 255 255 ... ##until i hit Control-C Traceback (most recent call last): File "C:/Documents and Settings/Cookie/Desktop/try.py", line 32, in ? doKeyEvent(key) File "C:/Documents and Settings/Cookie/Desktop/try.py", line 9, in doKeyEvent print ord(key) File "C:\PROGRA1\lib\idlelib\PyShell.py", line 1128, in write self.shell.write(s, self.tags) File "C:\PROGRA1\lib\idlelib\PyShell.py", line 1117, in write raise KeyboardInterrupt KeyboardInterrupt

The spaces before the '255' are points when i tried to exit using a space. A minor detail about the script at the site: it doesn't work as is, so i added a colon after the if-else lines in the first module and changed all references to 'ky' to 'key' for consistency. Any ideas as to why this doesn't work?

Thanks in advance, Orri

P.S.: I just had a thought that perhaps it was something with IDLE, and since it does work on the Python command line, i suspect that there might be an issue with IDLE's way of handling msvcrt.getch().
