So now I have, thanks to Danny Yoo:

=====================================
class _Getch:
     """Gets a single character from standard input.  Does not echo to the
screen."""
     def __init__(self):
         try:
             self.impl = _GetchWindows()
         except ImportError:
             self.impl = _GetchUnix()

     def __call__(self): return self.impl()

class _GetchWindows:
     def __init__(self):
         import msvcrt

     def __call__(self):
         import msvcrt
         return msvcrt.getch()

c = 0
getch = _Getch()
while True:
     c += 1
     if getch == "k":
         break
print c
================================================

No more errors, but it doesn't do what I wanted. More help, please.
