1、使用有意义的变量名（Use meaningful variable names）# Bad codex = 10y = 20# Good codestudent_count = 10teacher_count = 20 "Use meaningful variable names" 是 Python 中的一条编码原则，指的是使用有意义的变量名。中文可以翻译为“使用有意义的变量名”。在编
A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ ) Variable names are case-sensitive (firstname, Firstname, FirstName and FIRSTNAME) are different variables). It is recomended to use lowercase letters for variable name. 变量命名不能以数字开头 a=...
However, there is a convention that is followed by most Python code: a name prefixed with an underscore (e.g. _spam) should be treated as a non-public part of the API (whether it is a function, a method or a data member). It should be considered an implementation detail and ...
1. Python Variable Naming Convention While Python is flexible with variable names, there are a few rules and conventions: Variable names must start with a letter (a-z, A-Z) or an underscore (_). Variable names can contain letters, numbers, and underscores. Variable names are case-sensitive...
Note that the is_ naming pattern allows you to clearly communicate the variable’s purpose. However, this naming convention is just a common practice and not a requirement or something that Python reinforces.Remove ads Loop VariablesLoop variables help you process data during iteration in for ...

Exception Names Because exceptions should be classes, the class naming convention applies here. However, you should use the suffix "Error" on your exception names (if the exception actually is an error). Global Variable Names (Let's hope that these variables are meant for use inside one module...
Python for 循环可以遍历任何可迭代对象,如一个列表或者一个字符串 for <variable> in <sequence>: <statements> else: <statements> ②:while循环 while 判断条件(condition): 执行语句(statements)…… 同样需要注意冒号和缩进。另外,在 Python 中没有 do..while 循环 ...
It isn't required to call variable arguments args. You can use any valid variable name. Although it's common to see *args or *a, you should try to use the same convention throughout a project.In this case, *args is instructing the function to accept any number of arguments (including...
