将对象转换为日期时间引发错误

您使用了错误的格式。 '24 October 2018' 使用 format="%d %B %Y" . 将列出格式说明符 here .

编辑:-演示-

>>> import pandas as pd
>>> df = pd.DataFrame({'date':['24 October 2018', '23 April 2018', '18 January 2018']})
>>> df.date = pd.to_datetime(df['date'], format="%d %B %Y")
>>> 
>>> df
        date
0 2018-10-24
1 2018-04-23
2 2018-01-18
>>>
>>> df['date'][0]
Timestamp('2018-10-24 00:00:00')
>>> df['date'][0].month
10

>>> df['status'] = ['complete', 'complete', 'requested']
>>> df
        date     status
0 2018-10-24   complete
1 2018-04-23   complete
2 2018-01-18  requested
>>>
>>> df[df['status'] != 'complete']
        date     status
2 2018-01-18  requested

你可以用 pd.to_datetime 或者 datetime 图书馆

import datetime as dt
df['date'].apply(lambda x: dt.datetime.strptime(x,'%d %B %Y'))
