Pandas+Pyecharts | Visualization of historical weather data in Beijing in the past five years

##This issue uses python’s pyecharts visualization library Plot Beijing’s historical weather data to see historical high temperature and historical low temperature distribution, as well as wind power and wind direction distribution during the day and night,Hope it is helpful to everyone. If you have any questions or areas that need improvement, please contact the editor.

Involved libraries:
Pandas — Data processing
Pyecharts — Data visualization

1. Import module

import pandas as pd
from pyecharts.charts import Line
from pyecharts.charts import Bar
from pyecharts.charts import Scatter
from pyecharts.charts import Pie
from pyecharts.charts import EffectScatter
from pyecharts.charts import Calendar
from pyecharts.charts import Polar
from pyecharts import options as opts
import warnings
warnings.filterwarnings('ignore')

##2. Pandas data processing

##2.1 Read data

df_weather = pd.read_excel('./2018-2022年天气数据.xlsx')

There are a total of

1839 pieces of historical weather data from 2018 to 2022. 2.2 Processing minimum and maximum temperature data

df_weather_1 = df_weather.copy()
df_weather_1[['最低气温','最高气温']] = df_weather_1['最低气温/最高气温'].str.split(' / ',expand=True) 
df_weather_1['最低气温'] = df_weather_1['最低气温'].str[:-2]
df_weather_1['最高气温'] = df_weather_1['最高气温'].str[:-1]
df_weather_1['最低气温'] = df_weather_1['最低气温'].astype('int')
df_weather_1['最高气温'] = df_weather_1['最高气温'].astype('int')

2.3 处理日期数据

df_weather_1['日期'] = pd.to_datetime(df_weather_1['日期'],format='%Y年%m月%d日')
df_weather_1['日期s'] = df_weather_1['日期'].dt.strftime('%Y/%m/%d')

2.4 处理风力风向数据

3. Pyecharts数据可视化
