[Python] Improve Python consistency: "variable in function should be lowercase" (N806)

The repo contains roughly 80 Python scripts. "snake_case" naming is used for
local variables in all those scripts. This is the form recommended by the PEP 8
naming recommendations (Python Software Foundation) and typically associated
with idiomatic Python code.

However, in nine of the 80 scripts there were at least one instance of
"camelCase" naming prior to this commit.

This commit improves consistency in the Python code base by making sure that
these nine remaining files follow the variable naming convention used for
Python code in the project.
