使用*args和`kwargs**: 如果你想让函数能够接受任意数量的关键字参数,可以使用kwargs。kwargs`会捕获所有未命名的关键字参数,并将它们作为一个字典传递给函数。 defdescribe_pet(pet_name, animal_type, **kwargs): description =f"{pet_name}is a{animal_type}"forkey, valueinkwargs.items(): description...

In order to pass multiple argument values to the function, Python provides us with Arbitrary Arguments also known as Python *args. In this, we use the asterisk (*) to denote this method before the parameter in the function. The asterisk (*) allows us to pass ...
方法二:使用*args和**kwargs 另一种解决方法是使用可变长度参数*args和**kwargs。可变长度参数允许我们在函数调用时传递任意数量的参数,无论是位置参数还是关键字参数。 下面是一个示例: defmy_function(*args,**kwargs):forarginargs:print(arg)forkey,valueinkwargs.items():print(key,value)# 调用函数时,...

若使用位置参数传参,按照顺序,所有多余的参数均会被*args接收,keyword_only_arg并不会被自动填充,除非主动使用关键字参数对keyword_only_arg参数进行填充。 值得注意的是,仅限关键字参数仅能通过关键字参数的形式进行填充,并且Python要求所有的形参都被填充。这导致,对于没有默认值的仅限关键字参数必须使用关键字参数...
