Chapter 3 reverse_shell_py [Errno 9] Bad file descriptor on line os.dup2(s.fileno(),0)

Guys, I just found out that os.dup2 and socket.fileno() does not work on Windows as it is written on docs, as follows:

socket.fileno()
Return the socket’s file descriptor (a small integer). This is useful with select.select().

Under Windows the small integer returned by this method cannot be used where a file descriptor can be used (such as os.fdopen()). Unix does not have this limitation.
