Python allows functions to have default argument values. Default arguments are used when no explicit values are passed to these parameters during a function call. Let's look at an example. defgreet(name, message="Hello"):print(message, name)# calling function with both argumentsgreet("Alice",...

<function get_0_1_2 at0x00B2CB70> 我们定义了一个函数get_0_1_2,并且可以查看到这确实是函数类型。但与一般的函数不同的是,get_0_1_2的函数体内使用了关键字yield,这使得get_0_1_2成为了一个生成器函数。生成器函数的特性如下: 调用生成器函数将返回一个生成器; ...
This is the same as code blocks associated with a control structure, like an if or while statement. The syntax for calling a Python function is as follows: Python <function_name>([<arguments>]) <arguments> are the values passed into the function. They correspond to the <parameters> in...
