python如何对日期做遍历？有没有类似range的函数？

pandas里有date_range，很方便

import pandas as pd
pd.date_range('2018-09-01', '2018-09-07', freq='D')

输出结果为

DatetimeIndex(['2018-09-01', '2018-09-02', '2018-09-03', '2018-09-04',
               '2018-09-05', '2018-09-06', '2018-09-07'],
              dtype='datetime64[ns]', freq='D')

from datetime import date, timedelta

d1 = date(2019, 5, 10)  # start date
d2 = date(2019, 5, 20)  # end date
dates_range = [d1 + timedelta(i) for i in range((d2-d1).days + 1)]
