How to append output of “python --version” to a file in bash shell?

Question

python --version outputs to STDERR.

You need to merge STDERR into STDOUT:

python --version >> path.log 2>&1

For reference, you can verify such behavior by saying:

$ python --version 1>/dev/null
Python 2.7.4

The STDOUT in the above example was redirected to /dev/null. This would imply that the output is being sent to STDERR.
