Using Python Version 3.9.1 on Windows 10.
I'm a novice at Python and practicing by making a simple text-based zombie survival game.In its current build, you define your character attributes before fighting off a never-ending horde of zombies.
However, I've come across a couple of errors: one when trying to adjust my in-game stats and when I start the game.
Current game code
When I try to enter an integer value to spend points to increase or decrease
an in-game stat.
Occurs when I enter "quit" in the character creation stage and start the game.
