One cannot write to stdin:
>>> sys.stdin.write("1\n")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
IOError: [Errno 9] Bad file descriptor
But it is possible to explicitly open the current console for reading
and writing and do I/O regardless of stdin/stdout/stderr redirects:
>>> tty = open("/dev/tty", "r+")
>>> tty.write("1\n")
1
>>> line = tty.readline()
DDD
>>> line
'DDD\n'

Programmers don't die, they just GOSUB without RETURN.
