When working with a function that has both default and non-default arguments, consider using keyword arguments in the function call to make the code more readable and less error-prone. By following these best practices, you'll be able to write more robust and maintainable Python code ...
In a function, the order in which arguments must appear is: Positional arguments (non-default) Keyword arguments (default) Keyword-only arguments (*args) Variable keyword arguments (**kwargs) If you do not adhere to this order, Python returns an error message. An Example Scenario Write a pr...
命名空间分类: 1. 全局命名空间--> 我们直接在py文件中, 函数外声明的变量都属于全局命名空间 2. 局部命名空间--> 在函数中声明的变量会放在局部命名空间 3. 内置命名空间--> 存放python解释器为我们提供的名字, list, tuple, str, int这些都是内置命名空间 a = 10#全局名称空间中的内容deffn():#fn也在...
