如何使用python从timedelta变量中删除秒和微秒。我有以下数据框，我想删除秒。

df['Duration'] = ['03:12:37.771200','06:52:24.764500','13:19:57.325200','15:01:07.000200','04:05:06.722200','01:10:07.456200']

Answer 1

将round方法与'T'分开使用

df['Duration'] = pd.to_timedelta(df['Duration']).round('T')

print(df)

   Duration
0  03:13:00
1  06:52:00
2  13:20:00
3  15:01:00
4  04:05:00
5  01:10:00

您也可以使用floor

df['Duration'] = pd.to_timedelta(df['Duration']).floor('T')

print(df)

   Duration
0  03:12:00
1  06:52:00
2  13:19:00
3  15:01:00
4  04:05:00
5  01:10:00

如果需要从timedelta转换为numpy array然后转换为timedelta64[m]的秒数：

df['Duration'] = df['Duration'].values.astype("timedelta64[m]")

dur = ['03:12:37.771200','06:52:24.764500','13:19:57.325200',
       '15:01:07.000200','04:05:06.722200','01:10:07.456200']
df = pd.DataFrame({'Duration':dur})

df['Duration'] = pd.to_timedelta(df['Duration']).values.astype("timedelta64[m]")
print (df)
   Duration
0  03:12:00
1  06:52:00
2  13:19:00
3  15:01:00
4  04:05:00
5  01:10:00
