Python global variable across functions

Python global variables can be across functions because global variables are defined outside any function. You can access and modify this variable by any function in the program.

Simple example code defining a global variable and using it in multiple functions.

def increment():
    global count
    count += 1

def decrement():
    global count
    count -= 1
    print("count: ", count)


def print_count():
    print("Final count: ", count)
