您可以尝试以下方法：
import pandas as pdimport numpy as npfrom datetime import datetime, timedeltadate_today = datetime.now()days = pd.date_range(date_today, date_today + timedelta(7), freq='D')np.random.seed(seed=1111)data = np.random.randint(1, high=100, size=len(days))df = pd.Dataframe({'test': days, 'col2': data})df = df.set_index('test')print(df)test 2017-03-22 10:07:41.914019 292017-03-23 10:07:41.914019 562017-03-24 10:07:41.914019 822017-03-25 10:07:41.914019 132017-03-26 10:07:41.914019 352017-03-27 10:07:41.914019 532017-03-28 10:07:41.914019 252017-03-29 10:07:41.914019 23
