python

To see the version:

$ python --version
Python 2.7.17
$ python -V

To remove Python from the version:

$ python -V 2>&1 | awk '{print $2}'
2.7.17

We’re redirecting stderr to stdout with 2>&1 because python writes the version to stderr.

$ python -V 2>&1 | awk '{print $2}' | awk -F. '{print $1}'
