Is there a way to read from stdin in Python?

sysUse the module

import sys
for line in sys.stdin:
    print line

If you want to get the file name as command line argument and read the file, We recommend the fileinput module. If you're given a file name, read it to me If you're not given anything, read it on stdin.

import fileinput
for line in fileinput.input():
    pass
