sys.stdin is of no particular type, but must at least have a .read method.

 >>> import sys; sys.stdin
should give a hint.  In the standard REPL,

<_io.TextIOWrapper name='<stdin>' mode='r' encoding='utf-8'>

As others said, actually look in the io module doc.  You might spend 
some time reading the doc to get an idea of what is going on.  If you 
run from IDLE, you currently get

<idlelib.run.StdInputFile object at 0x00000243F6D6FBB0>
(I should make that more like the REPL answer.)
