python - 为什么 sys.exit() 不终止脚本

Question

当输入 NO 或 N 时文件一直在运行，为什么？

while True:
        game_choice = input('Do you want to play? ').lower()

    if game_choice == 'yes' or 'y':
        break
    elif game_choice == 'no' or 'n':
        sys.exit()
    else:
        print('Please answer only Yes/y or No/n')
        continue

Answer 1

您的 or 陈述不正确or y总是正确的，试试这个：

import sys

while True:
    game_choice = str(input('Do you want to play? ')).lower()
    if game_choice == 'yes' or game_choice == 'y':
        print("yes")
        break
    elif game_choice == 'no' or game_choice == 'n':
        sys.exit()
    else:
        print('Please answer only Yes/y or No/n')
        continue

或更好的版本：

import sys

while True:
    game_choice = str(input('Do you want to play? ')).lower()
    if game_choice in ['yes', 'y']:
        print("yes")
        break
    elif game_choice in ['no', 'n']:
        sys.exit()
    else:
        print('Please answer only Yes/y or No/n')
        continue
