本文将指导您如何在Python 3.6中使用静态类型声明变量。通过本教程，您将学会如何为字符串、整数、布尔值、列表及字典等数据类型设置静态类型，并了解如何在编码过程中自动检查类型错误。

In this lesson, you will learn how to statically type variables in Python 3.6 Static typing can help you avoid errors when consumers of your variables and functions call them with the incorrect data type. You will learn how to statically type strings, integers, booleans, Lists and Dicts. You will also learn how to automatically check for typing errors when coding and as part of your build workflow.

from typing import Dict, List


def add_num(a: int, b: int):
    return a + b


my_string: str

my_bool: bool


my_nums: List[int]

my_dict: Dict[str, int] = {
    "Patriots": 23,
    "Falcons": 7
}
