不过，之所以会出现这种情况，也许跟他的预设立场有关：他似乎认为“Python is fine without a switch statement”，因此尽管写了很长的 PEP，但只是在把问题复杂化，把议题搁置起来。最后，他在 PyCon 上做了一个小范围调查，借此“名正言顺”地拒绝了自己发起的 PEP，试图堵住众人的悠悠之口……4、未来
When Should You Use the Python Case Statement? Match-case is powerful, but you don’t always need it. Here’s when to use it: When you have many conditions: If you have more than 3-4 elif statements, consider match-case. When you’re checking patterns: If you need to check the str...
What is a guard in a match-case statement? A guard is a condition specified aftercasethat further refines when a case should match. For example: matchvalue:casexifx>10:print("Value is greater than 10.") Can you use match-case with Python versions earlier than 3.10?

排序问题是所有程序员一定会遇到的问题,Python内置的排序工具sort()和sorted()功能强大,可以实现自定义的复杂式排序。平时我们使用两个函数可能没有仔细研究过它们的区别,随想随用了。但实际上二者还是有很大的去别的,在一些场景中不同互换使用。 本篇将会介绍如何对不同数据结构中的各种类型的数据进行排序,自定义顺...
Python uses indentation to determine context, so we know that our function has ended when our indentation returns to the same indentation as our function statement. Now that we have the parsed data in our parser object, we are going to directly access the entry groupings that it gathered. ...
The for statement in Python differs a bit from what you may be used to in C or Pascal. Rather than always iterating over an arithmetic progression of numbers (like in Pascal), or giving the user the ability to define both the iteration step and halting condition (as C), Python’s for...
