如下: def function_name(parameter1: type, parameter2: type, ...) -> return_type: # function body 类型提示(type hint)在Python中用于增强代码可读性和跨语言移植性。尽管静态类型限定不会改变运行时行为,它可以帮助开发者明确函数参数和返回值的预期类型,提高代码质量。

1. 2. 3. 在这里,function_name是函数的名称,parameter是我们将要传入的参数。 示例代码 defadd_values(x):# 该函数接受一个参数 xpass 1. 2. 3. 在上面的代码中,我们定义了一个名为add_values的函数,但它还没有执行任何操作。 步骤2:添加类型提示 Python 3.5 及其以上版本引入了类型提示(Type Hint),使...

The->int at the end of the function definition indicates that the function returns an integer. This is known as type hinting and is used to help with code readability and debugging. Please note that this feature isnot enforcedin Python and it's just used as a hint for developer and IDEs...
annotation -- 标注关联到某个变量、类属性、函数形参或返回值的标签,被约定作为 type hint 来使用。 局部变量的标注在运行时不可访问,但全局变量、类属性和函数的标注会分别存放模块、类和函数的annotations特殊属性中。 参见 variable annotation、function annotation、PEP 484 和 PEP 526,对此功能均有介绍。
