How about with a file-like object? I haven't tested this with subprocess
so you might want to read the manual on files if it doesn't work[1].
import sys
class ErrorFile(object):
def _error(self, *args, **kwargs):
raise AssertionError("Illegal Access")
def _noop(self, *args, **kwargs):
pass
close = flush = seek = tell = _noop
next = read = readline = readlines = xreadlines = tuncate =
_error
truncate = write = writelines = _error
sys.stdin = ErrorFile()
print raw_input("? ")
