Finally, we print out the result using the print() function. We use string concatenation to construct a message that includes the original input values as well as the result. The print() function can take multiple arguments, which are separated by commas. In this case, we’re using commas ...
2. Arguments Immutable arguments are effectively passed “by value.” (int,string,tuple) (复制) Mutable arguments are effectively passed “by pointer.” (list, dictionary) (引用) >>>defchanger(a, b):#Arguments assigned references to objects... a = 2#Changes local name's value only... b...
def functionName(params): # 假如这个函数就是输出欢迎光临 print('欢迎光临') 函数使用:函数名 + () 借用菜鸟教程的一张图来更加形象的解释 def 是defnie定义的意思,max呢就是函数名称,通常函数名要与函数功能一致,这样看代码的人就能秒懂这个函数是干啥的,一对括号括起来呢是固定语法,括号内可以有参数也...

高阶函数英文叫Higher-order function 8.1实参和形参 形参:函数完成其工作所需要的一项信息。 实参:调用函数时专递给给函数的信息。 8.2传递参数 函数定义中可能包含多个形参,因此函数调用时也可能包含多个实参。向函数传递实参的方式很多,可使用位置实参,这要求实参的顺序与形参的顺序相同;也可使用关键字实参,其中每个...
以上代码定义了一个名为get_arguments的装饰器,它接受一个函数作为参数,并返回该函数的参数名称列表。然后我们定义了一个名为my_function的函数,并使用get_arguments装饰器获取了该函数的参数列表。 方法三:使用inspect模块和函数注解 Python 3引入了函数注解的概念,我们可以在函数定义中使用注解来指定参数的类型。inspec...
