如果在这么短的程序中,每个变量都像this_is_a_variable_name一样,这么长,反而会显得很不协调、很奇怪。 如果我们的程序存在比较复杂的嵌套关系,而且一个变量在总共大几百行代码中的多个位置均有出现,那么我们就不能用i来给一个变量命名了,这是我们就要让这个变量的名字包含足够多的信息,我们才能有效地知道,它是...

However, this is just a naming convention and doesn’t prevent developers from assigning new values to your constant. So, you need to be careful and never write code that changes the values of constants. To illustrate how to use constants instead of using global variables, say that you have...
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...
In Python tutorial, learn the basics of variables, naming conventions, and the difference between local and global variables with examples. In Python, a variable is used to store and manipulate data. We can think of a variable as a named container that holds a value. ...
In this example, the is_adult variable is a flag that changes depending on the value of age. 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 ...

Prescriptive: Naming Conventions|规定性:命名约定 Names to Avoid|应避免使用的名字 永远不要将字符 'l'(小写字母 "el")、'O'(大写字母 "oh")或 'I'(大写字母 "eye")作为单个字符的变量名使用。 在某些字体中,这些字符与数字 1 和 0 难以区分。当有使用 'l' 的冲动时,请改用 'L'。
