Apologizes, I should have been a more careful with my wording. Within Python you need to execute an "import" statement to pull in mysql support.

I don't know why, but I often think printf() is built into "C" even though everyone here knows you need to do an "#import <stdio.h>" to pull it in. Sloppy thinking I suppose.

I ignored Python for a long time until I realized that most of my system admin tools in CentOS-7 were written in Python. This became apparent when someone did not properly install Python3 on one of our 6ix systems which broke all the scripts dependent upon Python2 (couldn't run firewall-cmd, yum, etc). Not sure why the authors of those scripts did not use the shebang hack. Perhaps this is one way RedHat ropes people into support contracts for RHEL :-)
