Finally, the least frequently used option is to specify that a function can be called with an arbitrary number of arguments. These arguments will be wrapped up in a tuple (see Tuples and Sequences). Before the variable number of arguments, zero or more normal arguments may occur.最后，...

python中可变参数(Variable Arguments) 简介:【6月更文挑战第10天】 在Python中,你可以使用两种主要的方式来处理可变数量的参数: 使用星号(*)处理位置参数:当在函数定义中使用一个星号前缀时,它会将传入的多个位置参数收集到一个元组中。 deffunc(*args):forarginargs:print(arg) func(1,2,3,4)# 输出: 1 ...
Within the function, args is now available as the variable that holds all arguments as a tuple. Try out the function by passing any number or type of arguments:Python Kopioi variable_length() () variable_length("one", "two") ('one', 'two') variable_length(None) (None,) ...
Python allows you to use variable-length argument lists in function definitions. This means that you can pass an arbitrary number of arguments to a function using the *args syntax. For example: def foo(*args): for arg in args: # Do something ...

Python Function With Arbitrary Arguments Sometimes, we do not know in advance the number of arguments that will be passed into a function. To handle this kind of situation, we can usearbitrary arguments in Python. Arbitrary arguments allow us to pass a varying number of values during a functio...
如果一个函数接受任意数量的(位置)参数,那么我们称该函数使用了可变参数(variable arguments)。示例: deff(x, *args): ... 函数调用: f(1,2,3,4,5) 额外的参数作为元组进行传递: deff(x, *args):# x -> 1# args -> (2,3,4,5) 可变关键字参数(**kwargs) ...
*args (arguments)表示任何多个无名参数, 它本质上是一个 tuple ** kwargs (keyword arguments)表示关键字参数, 它本质上是一个 dict 注意:使用时必须要求 *args 参数列要在** kwargs 前面 【因为位置参数在关键字参数的前面。】 二args 和 ** kwargs的用法实例 ...
