“星期五我恋爱了”程序-Python查询

Posted 2023-01-06

感谢您的帮助。我已在下面的评论中提及了我的问题。

这是一个测试/有趣的项目，我正在做一个编码类型的程序，伴有The Cure的歌曲“星期五我恋爱”。基本上，您可以在播放歌曲时输入歌曲。基本上，您键入：“ Monday”程序以“ Blue”响应。在吉他声部，我希望用户按下Enter键（创建了ValueError），并且音符将使用随机脚本显示在页面上。

import random

print('OOOOOH! Welcome to the Day-bot generator')
print('Choose your day of the week.')
days = ['monday', 'tuesday', 'wednesday', 'thursday', 'friday', 'saturday', 'sunday']

while True:
        for stanza1 in range(0,5):
            fiil = ['Blue', 'Gray', 'Too', 'I Dont Care About You', 'IM IN LOVE']
            x = input()
            print(fiil[(days.index(x))])

        for stanza1 in range(0,7):

            fiil = ['Fall Apart', 'Break my Heart', 'Break my Heart', 'Doesnt Even Start', 'IM IN LOVE', 'Wait', 'Always Comes too late']
            x = input()     
            print(fiil[(days.index(x))])

if ValueError: # NEED HELP with the CODE here.
            b=['~~~~', '~~♫~~~~~♫','~~~~♩~~♫~', '~~
~~~~♫♫~~', '~~~♫,~~♩~~','~~~~♫', '♬~~~~~', '~~~♬♩~~~~']
            z= random.randint(0,7)
            print(b[z])



        ## Whenever I type a false value. nice squiggly music come out.
        ## But...it jumps back to the start of the code everytime
        ## I need it to jump back to where the user left off. 
##Thank you for helping. Its my third day writing any kind of code so pls forgive me for any bad questions.

答案

欢迎您，祝贺您开始第一个项目。这听起来有些古怪，但是发布可重现的代码很有帮助。下次您应该确保标题是一个实际的问题：甚至像“为什么我的程序跳回到代码开头？”之类的东西。比您目前拥有的有帮助。

通常，请尽量不要依赖异常来指导您的控制流程。由于您已将要接受的内容列入白名单（days），因此可以仅使用简单的if语句。

if x in days: 
    # Do whatever`

请注意，您可能希望允许用户键入“ Monday”或“ monday”，以便将输入转换为小写。

 if x.lower() in days: 
    # Do whatever`

由于您将多次调用随机笔记，因此应将其包装在函数中。

def printRandomNotes():
    b=['~~~~', '~~♫~~~~~♫','~~~~♩~~♫~', '~~
~~~~♫♫~~', '~~~♫,~~♩~~','~~~~♫', '♬~~~~~', '~~~♬♩~~~~']
    z= random.randint(0,7)
    print(b[z])

所以现在让我们结合整个程序。

import random

print('OOOOOH! Welcome to the Day-bot generator')
print('Choose your day of the week.')
days = ['monday', 'tuesday', 'wednesday', 'thursday', 'friday', 'saturday', 'sunday']

def printRandomNotes():
    b=['~~~~', '~~♫~~~~~♫','~~~~♩~~♫~', '~~~~~~♫♫~~', '~~~♫,~~♩~~','~~~~♫', '♬~~~~~', '~~~♬♩~~~~']
    z= random.randint(0,7)
    print(b[z])

while True:
    for _ in range(0,5):
        fiil = ['Blue', 'Gray', 'Too', 'I Dont Care About You', 'IM IN LOVE']
        x = input()
        if x.lower() in days:
            print(fiil[(days.index(x.lower()))])
        else:
            printRandomNotes()

    for _ in range(0,7):
        fiil = ['Fall Apart', 'Break my Heart', 'Break my Heart', 'Doesnt Even Start', 'IM IN LOVE', 'Wait', 'Always Comes too late']
        x = input()
        if x.lower() in days:
            print(fiil[(days.index(x.lower()))])
        else:
            printRandomNotes()

此代码仍然不是DRY，但我现在不必担心样式过多。祝您编码愉快。
