Only on 3.4. Python prints the version on stdout since 3.4 -- before it used stderr: 3.3$ ./python -V 2> /dev/null 3.3$ ./python -V > /dev/null Python 3.3.2+ 3.4$ ./python -V 2> /dev/null Python 3.4.0a1+ 3.4$ ./python -V > /dev/null This might also explain why argparse uses stderr (other modules/scripts in the stdlib might do the same too).

Python prints the version on stdout since 3.4 -- before it used stderr:
3.3$ ./python -V 2> /dev/null
3.3$ ./python -V > /dev/null
Python 3.3.2+

3.4$ ./python -V 2> /dev/null
Python 3.4.0a1+
3.4$ ./python -V > /dev/null

This might also explain why argparse uses stderr (other modules/scripts in the stdlib might do the same too).
