Python自定义函数的参数

在Python中自定义的函数可以有三类不同的参数

• formal parameters
• positional arguments
• Keyword Arguments

This may be combined with a formal parameter of the form *name (described in the next subsection) which receives a tuple containing the positional arguments beyond the formal parameter list. (*name must occur before **name.) For example, if we define a function like this:
