Python 如何转换timedelta64[ns]对象-1天+；23:40:00到-20？

“2019-07-29 10:00:00”-“2019-07-29 10:20:00”=-1天+23:40:00

我只想等一会儿

diff = pd.to_datetime(pd.Series(['2019-07-29 10:00:00', '2019-07-30 10:30:00'])) - pd.to_datetime(pd.Series(['2019-07-29 10:20:00', '2019-07-30 10:15:00']))
print(diff)
print(diff.dt.components)

0   -1 days +23:40:00
1            00:15:00
dtype: timedelta64[ns]
   days  hours  minutes  seconds  milliseconds  microseconds  nanoseconds
0    -1     23       40        0             0             0            0
1     0      0       15        0             0             0            0

我想这样隐蔽起来

print(diff)
0   -20
1    15

试试这个：

df = pd.DataFrame(diff.dt.components)
df['new'] = df['minutes'] + 60 * df['hours'] + 1440 * df['days']
print(df['new'])

试试这个：

df = pd.DataFrame(diff.dt.components)
df['new'] = df['minutes'] + 60 * df['hours'] + 1440 * df['days']
print(df['new'])
