Hi,

I'm not sure why you think this is fixable, given the comments on the tracker. What is your plan?

>>> from sys import stdin >>> str=stdin.read() hello hello world CTRL+D CTRL+D

Can anyone tell me where is stdin.read() function defined? Or where is sys.stdin defined?

Can I suggest you try to investigate it a bit yourself:

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

So it's a TextIOWrapper from the _io module (which is really the implementation of the io module). You'll find its source in Modules/_io. TextIOWrapper objects are defined in Modules/_io/textio.c. But as you know, they wrap buffered I/O objects, which are defined in Modules/_io/bufferedio.c. In sys.stdin's case, the buffered I/O object wraps a raw FileIO object, defined in Modules/_io/fileio.c:

sys.stdin.buffer <_io.BufferedReader name=''> sys.stdin.buffer.raw <_io.FileIO name='' mode='rb'>

Regards

Antoine.
