Python猜数字代码故障排查：输入首猜数后程序终止

你的代码核心问题是未初始化game_over变量：

• 代码直接使用while not game_over作为循环条件，但game_over在这之前从未被定义过，第一次执行循环时会触发NameError，导致程序直接终止。

修复后的完整代码 #

import random
winning_number = random.randint(1,100)
guess = 1
# 初始化game_over变量为False，让循环可以正常启动
game_over = False
number = int(input("guess a number between 1 and 100: "))

while not game_over:
    if number == winning_number:
        print(f"you win, and you guessed this number in {guess} times ")
        game_over = True
    else:
        if number < winning_number:
            print("too low")
            guess += 1
            number = int(input("guess again: "))
        else:
            print("too high")
            guess += 1
            number = int(input("guess again: "))

额外优化建议（可选） #

你可以把输入逻辑整合到循环内部，减少重复代码，让结构更简洁：

import random
winning_number = random.randint(1,100)
guess = 0
game_over = False

while not game_over:
    guess += 1
    number = int(input("guess a number between 1 and 100: "))
    if number == winning_number:
        print(f"you win, and you guessed this number in {guess} times ")
        game_over = True
    elif number < winning_number:
        print("too low")
    else:
        print("too high")
