Please do not abuse the local namespace...

Use something else for this, a dictionary for example.

No. In a Python module, you would use "globals().get".
"globals()" gives you the module's dictionary.

A Python Script is a function. The builtin function
"locals()" returns the function's local namespace as a
dictionary. The effect of modifications to this dictionary
is undefined.

Almost surely, "locals" is not available in a Python Script.

You could also use "eval", but this, too, is not available
in a Python Script...

Thus, use a dictionary...
