temp = 5  # global variable
def passfun(x: int)-> int:
    print("temp in passfun = %d" % temp)
    return x + temp

def main():
    global temp
    temp = 10
    temp = passfun(temp)
    print("temp in main = %d" % temp)

if __name__ == "__main__":
    main()

def passfun(x: int)-> int:
    print("temp in passfun = %d" % temp)
    return x + temp

def main():
    temp = 10     # local variable
    temp = passfun(temp)
    print("temp in main = %d" % temp)

if __name__ == "__main__":
    main()
Output:
temp in passfun = 10
temp in main = 20
Output:
temp in passfun = 5
temp in main = 15
