Callinga function withactualparameter values to be substituted for the formal parameters and have the function code actuallyrunwhen the instruction containing the call is run. Also note that the function can be called multiple times with different expressions as the actual parameters (line 9 and aga...

FUNCTION ||--|{ PARAMETER PARAMETER ||--|| STRING 步骤说明 1. 定义函数 首先,我们需要定义一个函数,该函数将接受一个字符串作为参数。我们可以使用以下代码来定义函数: defmy_function(param):# 在这里编写函数的具体逻辑 1. 2. 在这段代码中,my_function是函数的名称,param是接受的参数。 2. 传参字符...
function_name 是函数的名称。按照 PEP 的要求,函数名称的命名方式与变量的命名方式和格式一样。 函数名称之后紧跟着 ([parameters]) ,函数名称和圆括号之间不能有空格,圆括号也不能省略。圆括号里面是这个函数的参数列表,如果此函数不需要参数,则可为空。。

在函数的形参中,如果同时有*parameter和**parameter,*parameter必须在**parameter前面。 def func(*args): print(args) func(33,44,55,66,77) func(*(33,44,55,66,77)) #运行结果 (33,44,55,66,77) (33,44,55,66,77) def func(**kwargs): print(kwargs) func(e=33,h=44,f=55,d=66,c...
From a function's perspective: A parameter is the variable listed inside the parentheses in the function definition. An argument is the value that is sent to the function when it is called. Number of Arguments By default, a function must be called with the correct number of arguments. Meanin...
Python中还有另一种参数,即可选参数(optional parameter)。函数只在需要时才会传入,并不是执行程序所必须的。如果没有传入可选参数,函数将使用其默认值 使用如下语法定义可选参数:[函数名]([参数名]=[参数值])。与必选参数一样,可选参数也得使用逗号分隔。一个带可选参数的函数示例如下: ...
In this function, you obtain the value of the name query parameter from the params parameter of the HttpRequest object. You read the JSON-encoded message body by using the get_json method. Likewise, you can set the status_code and headers for the response message in the returned Http...
