# cityCode 替换为具体某一个城市的对应编号
# 1、发送请求,获取数据
url = f 'http://wthrcdn.etouch.cn/weather_mini?citykey={cityCode}'
res = requests.get(url)
res.encoding = 'utf-8'
res_json = res.json()
# 2、数据格式化
data = res_json[ 'data' ]
city = f "城市:{data['city']}\n"
# 字符串格式化的一种方式 f"{}" 通过字典传递值
today = data[ 'forecast' ][ 0 ]
date = f "日期:{today['date']}\n" # \n 换行
now = f "实时温度:{data['wendu']}度\n"
temperature = f "温度:{today['high']} {today['low']}\n"
fengxiang = f "风向:{today['fengxiang']}\n"
type = f "天气:{today['type']}\n"
tips = f "贴士:{data['ganmao']}\n"
result = city + date + now + temperature + fengxiang + type + tips
print (result)

1、使用Qt Designer绘制窗口,保存为ui文件
2、把ui文件转为py文件
(1)在生成的ui文件目录下,打开cmd
(2)输入以下命令(注意替换名称)
pyuic5 -o destination.py source.ui
3、信号与槽函数的连接

# 1、清空按钮与对应函数连接
clearBtn.clicked.connect(widget.clearResult)
# 2、查询按钮与对应函数连接
queryBtn.clicked.connect(widget.queryWeather)

4、调用主窗口类
