I just wrote the simple snippet below to try msvcrt out. I can add a Linux try block when I install Linux and actually find a wifi driver for it ;') I reproduced the error that puzzled me almost immediately. It was from hitting a function key. The snippet below worked fine for letters and such, but died when I hit a function key (although not all of them). I was decoding since msvcrt sends byte strings, but there was nothing in the utf-8 map for that key. The 2> redirect is sure handy for dos console error messages - something I'll have to remember ;') from msvcrt import * while True: if kbhit(): key = getch() if key == b'\xe0' or key == b'\000': print('special key follows') key = getch() print(str(key, encoding='utf-8')) #got rid of this decode after a function key error else: print('The key is: ', str(key, encoding='utf-8')) Traceback (most recent call last): File "keyget.py", line 9, in <module> print(str(key, encoding='utf-8')) UnicodeDecodeError: 'utf-8' codec can't decode byte 0x85 in position 0: invalid start byte -- Jim "What a rotten, failed experiment.
