By understanding and following the Python identifier rules, you set a strong foundation for writing clean, efficient code. These rules help you avoid mistakes and ensure that your code is both functional and re
For instance, you can use an identifier in your code only if it has been given a value; unassigned identifiers cause a runtime error. This means that if you type mgs when you meant msg, you’ll find out pretty quickly when Python complains about your code having a NameError. Store ...
Comments that contradict the code are worse than no comments. Always make a priority of keeping the comments up-to-date when the code changes! Comments should be complete sentences. If a comment is a phrase or sentence, its first word should be capitalized, unless it is an identifier that ...
Comments should be complete sentences. If a comment is a phrase or sentence, its first word should be capitalized, unless it is an identifier that begins with a lower case letter (never alter the case of identifiers!). If a comment is short, the period at the end can be omitted. Block...
The syntax of the Walrus operator is of the form NAME:= expr, where NAME is a valid identifier, and expr is a valid expression. Hence, iterable packing and unpacking are not supported which means, (a := 6, 9) is equivalent to ((a := 6), 9) and ultimately (a, 9) (where a...
1. The function code block starts with the def keyword, followed by the function identifier name and parentheses ().2、函数内容以冒号起始，并且缩进。2. The function content starts with a colon and is indented.3、函数的第一行语句可以选择性地使用文档字符串—用于存放函数说明。3. The first line...

通过该方法客户端可以将指定资源的最新数据传送给服务器取代指定的资源的内容。 DELETE:DELETE请求用于请求服务器删除所请求URI(统一资源标识符,Uniform Resource Identifier)所标识的资源。DELETE请求后指定资源会被删除,DELETE方法也是幂等的。 CONNECT:CONNECT方法是HTTP/1.1协议预留的,能够将连接改为管道方式的代理服务...
