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()

class _GetchUnix:

class _GetchWindows:

def __call__(self):

return msvcrt.getch()
getch = _Getch()
Sadly this also fails with:
Traceback (most recent call last):
File "<pyshell#2>", line 1, in -toplevel-
a = getch()
File "/home/chris/getch.py", line 10, in __call__
def __call__(self): return self.impl()
File "/home/chris/getch.py", line 19, in __call__
fd = sys.stdin.fileno()
AttributeError: fileno
What is fileno, and why might I not have it?
