fileno() in not supported. Is it only in 3.1? What is the workaround?
You have been asked many times about the details of your environment.
Especially, you have been told that it is important to know if you
directly use the Python CLI or some GUI like IDLE.
I just tested the latter thing and found out that it indeed makes a
difference, as it introduces a replacement for the std* stuff you are
missing:
>>> sys.stdin
<idlelib.PyShell.PseudoInputFile object at 0x0000000002EAD588>
>>> sys.stdout
<idlelib.PyShell.PseudoOutputFile object at 0x0000000002EAD5C0>
>>> sys.stderr
<idlelib.PyShell.PseudoOutputFile object at 0x0000000002EAD5F8>
Calling .fileno() on such a Pseudo*File just raises an
UnsupportedOperation exception.
This is in contrast to using the CLI directly.
