此处的原始数据表是全国各省的实时数据集，现在只获取江苏省份的数据
engine = create_engine(mysq_conn) # 具体内容以自己上就可以为准
select_data = "select * from table_data where area='江苏'order by local_time desc"
df = pd.read_sql(sql=select_data, con=engine)
df.head()
#转化获取年-月-日
new_df['日期'] = new_df['local_time'].dt.year.map(str)+'-'+new_df['local_time'].dt.month.map(str)+'-'+new_df['local_time'].dt.day.map(str)
