你必须执行这个函数，你的输出暗示你做了类似于

print(playGame2)

代替

playGame2()

def playGame2():
    number = random.randrange(1,100)
    guess = input("I'm thinking of a number between 1 and 100. Guess what it is: ")
    if str(number) == guess:
        print("That is correct!")
    else:
        print("Nope, I was thinking of %s" % number)

试试看。我刚刚运行的很好。要在空闲状态下或者你可以访问它的地方使用playGame2（）。

你需要告诉python这有一个main函数，尝试在代码的末尾包含这个：

if __name__ == "__main__":
    playGame2()

把这个放在开头

希望它能帮助你。
