python - 为什么我会收到 NameError？

这是我要运行的代码的一部分:

def func1():
    a = True
    while a == True:
        try:
            guess = int(input("guess it: "))
            a = False
        except ValueError:
            print("Not a valid number.")

import random
number = random.randint(0, 50)
print("Im thinking of a number between 0 and 50,")

func1()

if guess == number:
    print("Perfect, you got it from the first try!")

我不知道为什么我得到这个:NameError: name 'guess' is not defined, even though I defined it in "func1"
