keyword argument(关键字参数): 在函数调用中前面带有标识符(例如name =)或者作为包含在前面带有**的字典里的值传入。举例来说,3 和 5 在以下对complex()的调用中均属于关键字参数: complex(real = 3, imag = 5) complex(**{'real': 3, 'imag': 5}) ...

Python的函数的输入参数有两种类型,一种是位置参数(positional argument),一种是关键字参数(keyword argument)。 所谓positional argument位置参数,是指用相对位置指代参数。关键字参数(keyword argument),见名知意使用关键字指代参数。位置参数或者按顺序传递参数,或者使用名字,自然使用名字时,对顺序没有要求。

python函数参数根据使用情况的不同需要分为Parameter和Argument两部分进行讨论。 python中有两种argument,分别是【位置参数】和【关键字参数】 位置参数【positional argument】使用时直接给出参数值,可以是简单值或者是一个带有*前缀的可迭代的元素表示,以内置函数complex()的调用为例: ...
实参(argument),全称为实际参数,是在调用时传递给函数的参数。实参可以是常量、变量、表达式、函数等。无论实参是何种类型的量,在进行函数调用时,它们都必须具有确定的值,以便把这些值传送给形参。 形参和实参的功能是数据传送。 在调用函数时,实参将赋值给形参。必须注意实参的个数、类型应与形参要一一对应,并且实...
