Answer 1

您可以使用weekday_name

df['date/time'] = pd.to_datetime(df['date/time'], format = '%d/%m/%Y %H:%M:%S')

df['Day of Week'] = df['date/time'].dt.weekday_name

你得到

    date/time   Day of Week
0   2018-05-07 09:28:00 Monday
1   2018-05-14 17:00:00 Monday
2   2018-05-15 17:00:00 Tuesday
3   2018-05-15 17:00:00 Tuesday
4   2018-06-23 17:00:00 Saturday
5   2018-06-29 17:00:00 Friday
