我有一个 timedelta 数据框
JC time
1 3days 21:02:05
2 1days 23:50:07
3 6days 19:28:36
但我想要
1 93:02:05
2 47:50:07
3 163:28:36
我该如何转换它？
使用、组合pd.to_timedelta https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.to_timedelta.html, Series.dt.components https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.Series.dt.components.html, DataFrame.agg https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.agg.html & Series.str.zfill https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.Series.str.zfill.html:
d = pd.to_timedelta(df['time']).dt.components[['days', 'hours', 'minutes', 'seconds']]
d['hours'] = d['hours'].add(d.pop('days') * 24)
df['time'] = d.astype(str).agg(lambda s: ':'.join(s.str.zfill(2)), axis=1)
Result:
# print(df)
JC time
0 1 93:02:05
1 2 47:50:07
2 3 163:28:36
