python - Python3：如何在需要整数的while循环中检查字符串

问题描述

在 Python3 中：如何在需要整数的 while 循环中检查字符串...

这是我目前的代码：我想用“quit”或“q”替换标记值“0”。我该怎么做？

import random

highest = 10
lowest = 1
counter = 0

random_number = random.randint(lowest, highest)
# The randint function is in the random function within the random MODULE imported above.

guess = int(input(f"Guess a number between {lowest} and {highest}. Enter '0' at any time to quit: "))

while guess is not random_number:
    if guess == 0:
        print("Quitting game.")
        break
    elif guess < random_number:
        counter += 1
        guess = int(input("Guess higher: "))
    elif guess > random_number:
        counter += 1
        guess = int(input("Guess lower: "))
    if guess == random_number:
        print(f"Correct! Well done!! You got it right after {counter} guess(es)!")

我想将标记值“0”更改为“q / quit”，但不知道如何...

解决方案

guess = int(in.... 不要将其转换为 int，而是转换为字符串。

然后看看字符串是“q”还是“quit”

如果不是 q 或退出，则将其转换为 int ： elif int(guess) < random_number:
