Except it is for me (and I don't know how it gets there):
$ which python
/usr/bin/python
$ file /usr/bin/python
/usr/bin/python: symbolic link to python-exec2c
$ file /usr/bin/python-exec2c

(SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for
GNU/Linux 3.2.0, stripped
$ set | grep -i py
$ python

The entry for /home/grante/.local/lib64/python3.6/site-packages (where
pip --user installs things) is in my path.
