How can I use if statements to check variables inside of function? [duplicate]

This question already has an answer here:

I am making a text based hacking game. How can I use if statements to check variables inside of function?

Error:

Traceback (most recent call last):
File "C:UsersuserDesktopPython ProjectsTextHackingGameStart.py", line 22, in <module>
if check == "start":
NameError: name 'check' is not defined


The code:

import time
import string
import os
import sys

print("-------------------------")
print("Welcome to [NAME_HERE]")
print("By ***************")
print("Copyright 2018")
print("-------------------------")
time.sleep(0.10)
os.system("cls")

global Check
global check

def StartOrChange():
print("Type 'Start' or 'Changelog'.")
Check = input("> ")
check = Check.lower

if check == "start":
pass
elif check == "changelog":
pass
else:
print("Please enter 'Start' or 'Changelog'")

When you declare your variables, use check = 0 and Check = 0, and inside the function StartOrChange() use

check = 0

Check = 0

StartOrChange()

def StartOrChange():
global Check
global check

print("Type 'Start' or 'Changelog'.")
Check = input("> ")
print (Check)
check = Check.lower()
