You can use a global variable within other functions by declaring it as global within each function that assigns a value to it:

globvar = 0
def set_globvar_to_one():
    global globvar    # Needed to modify global copy of globvar
    globvar = 1

def print_globvar():
    print(globvar)     # No need for global
