def mydemo(name): '函数定义过程中的name是叫形参' #因为它只是一个形式,表示占据一个参数位置 print('传递进来的' + name + '叫做实参,因为它是具体的参数值!') mydemo('john') #函数调用过程中传递进来的john叫做实参,因为它是具体的参数值! mydemo(name='john') #当函数调用时,传递实参过多,会搞...
arguments 和 parameter 的翻译都是参数,在中文场景下,二者混用基本没有问题,毕竟都叫参数嘛。 但若要严格再进行区分,它们实际上还有各自的叫法 parameter:形参(formal parameter),体现在函数内部,作用域是这个函数体。 argument :实参(actual parameter),调用函数实际传递的参数。 举个例子,如下这段代码,"error"为 ...
def functionname( parameters ): "函数_文档字符串" function_suite return [expression] 1. 2. 3. 4. 定义函数以def关键词开头,后面跟着函数名、圆括号()、括号中的参数、冒号; 接着,在缩进块中编写函数体,函数的第一行语句一般是写文档字符串,用于存放函数说明,也可以选择不写; Return[expression]表示结束...
In this example, we define a decorator that takes a function with a long parameter list and converts it into a function that takes a single argument. We apply this decorator to the foo function, and it now takes a single argument instead of four. In conclusion, these are some of the s...

Question 1: What is the purpose of default parameter values in Python functions? To enforce argument passing in the correct order. To allow a function to be called without explicitly providing all arguments. To restrict the number of arguments a function can accept. ...
