Python 3.x 如何给三个字母单独的任务

我希望用户能够输入E、N或H，然后打印他们选择的内容

import random

print('please enter one of three letters\n E for easy\n N for normal\n H for hard')    
difficulty = input()
if input().upper().startswith('E'):
    print('E was selected')
elif input().upper().startswith('N'):
    print('N was selected')
elif input().upper().startswith('H'):
    print('H was selected')
else:
    print('please enter E,N or H)

---

回复：

+1。好处：您通过执行

难度.upper（）

而不是

输入（）.upper（）

来识别问题。坏消息：在Python 3中，原始输入（）被重命名为

input（）

。丑八怪：今天是星期五，我们在StackOverflow。啊，很有趣。非常感谢。不太熟悉3.x

difficulty = input('please enter one of three letters\n E for easy\n N for normal\n H for hard')

if (difficulty.upper() == 'E'):
    # Do "E" things
    print('E was selected')
elif (difficulty.upper() == 'N'):
    # Do "N" things
    print('N was selected')
elif (difficulty.upper() == 'H'):
    # Do "H" things
    print('H was selected')
else:
    print('please enter E,N or H')
