How to print to stderr in Python?

by

I found this to be the only one short, flexible, portable and readable:

# This line only if you still care about Python2
from __future__ import print_function

import sys

def eprint(*args, **kwargs):
    print(*args, file=sys.stderr, **kwargs)

The optional function eprint saves some repetition. It can be used in the same way as the standard print function:

>>> print("Test")
Test
>>> eprint("Test")
Test
>>> eprint("foo", "bar", "baz", sep="---")
foo---bar---baz
