python如何制作的天气预报小工具

这篇文章主要介绍python如何制作的天气预报小工具，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！

一．准备工作

不需要准备。

二．预览

1.启动

启动以后自动定位所在城市，展示定位城市的天气。

2.添加城市

3.展示多个城市天气

添加天气之后能够显示多个城市天气信息。

三．设计流程

1.获取城市天气信息过程

用此流程图展示定位城市信息到获取城市天气信息过程。

四．源代码

python的数据类型有哪些?

python的数据类型：1. 数字类型，包括int（整型）、long（长整型）和float（浮点型）。2.字符串，分别是str类型和unicode类型。3.布尔型，Python布尔类型也是用于逻辑运算，有两个值：True（真）和False（假）。4.列表，列表是Python中使用最频繁的数据类型，集合中可以放任何数据类型。5. 元组，元组用”()”标识，内部元素用逗号隔开。6. 字典，字典是一种键值对的集合。7. 集合，集合是一个无序的、不重复的数据组合。
