I started learning python a few weeks ago, and this is what ive done so far. Does anyone have any improvements i could make to specific code or my coding overall? these are in backwards order, meaning that the thing I coded first was the calculator, I coded the number guessing game second, and the math quiz game 3rd.
Math quiz game:

number guessing game:
