Python：如何使这段代码变得更好？

WAP使用功能概念创建数学应用程序添加至少20-25个功能每个功能和用户输入的不同功能，以便根据功能选择任何功能要求用户输入

欢迎来到堆栈溢出！要获得有用的帮助，请查看。特别是，请尽量把你的问题具体化。此外，如果你想提出具体的批评，也许是一个更好的提问方式。（作为如何改进它的第一个建议，您可以将其格式设置为更易于阅读。缩进为4个空格的倍数，除了函数之间，不要添加空行，以使代码更易于阅读。）在粗略概述中，我可以说，您可以使用内置的

pow

函数，而不是定义自己的

exponent

函数，并且大多数其他函数可以从or模块导入。另外，Python中的

swap

可以写成

x，y=y，x

或

defswap（x，y）：返回y，x

（但它作为函数没有用处）。可以删除一些空行以缩短它。不要创建函数

sin（）

，而是直接使用

math.sin（）

——这样会减少代码。与其他

math

函数一起使用Silimar。制作一个字典

{user\u response:function\u name，…}

，然后选择包含用户响应的函数。。使用一个长字符串提示用户执行所需操作。
