Fix Boolean Conversion Issue from Shell to Python

[yfyeung]

Fixes a bug where the shell variable with a False value is passed to Python as a string, causing bool("False") to evaluate as True.

For example:

test.py:

import sys
print(type(sys.argv[1]))

python test.py False

Output:

<class 'str'>
