How can I make a BufferedReader object from a standard file object, like sys.stdin or what you get from 'open'?
(Background: I need a peek() method, which the standard file objects fail at having. Any suggestions to solve this issue are also welcome.)
I'd have sort of expected this to work, but it doesn't:
>>> import sys >>> import io >>> io.BufferedReader(sys.stdin) Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'file' object has no attribute 'readable'
(This is Python 2.7)
Hah, got it, at least for anything that has a file descriptor.
stream = sys.stdin, or open(...), etc. reader = io.open(stream.fileno(), mode='rb', closefd=False)
I was also looking for the same code for the same reason (using peek) awhile ago. And this works:
reader = io.open(sys.stdin.fileno())
