python - Why does it still say 0 although I am adding on to it?

Question

READ THIS FIRST BEFORE

• Firstly, allow me to explain what you should input to get the mistake.
  • Run the program.
  • Name your company to anything.
  • Then see company stats by clicking 1.
  • After that work on your company by clicking 2
  • Then hire people by clicking 1
  • Hire maybe two or three people by clicking the respective numbers.
  • Then click 6 and go back.
  • Then see the company stats again.
  • PROBLEM HERE. The number of employees remain the same

WHY?

What I think I did ?

• My problem is in the function employees() on line 24.

• Although I do employee_num += 1, the number of employees remain the same.

This is my question. Please tell me how to fix that and also provide a reason.

Answer 1

If you want to modify a variable in a function other than the place that variable exists, you need either a global or nonlocal statement, depending on whether your variable is global or not. Your employee_num is global, so you should put

global employee_num

as the first line of any function which will modify it.
