local isn't a keyword. Maybe you're thinking of the locals() function.
The global and nonlocal keywords define the scope of a name for the
entire block. You can't flip it on and off like a toggle switch. That
would give me headaches. Anyway, try to avoid globals and use
descriptive names. If you still have a clash, use globals()[name].
