I\'ve read loads of SO answers but can\'t find a clear solution.
I have this data in a df called day1 which represents hours:
day1
1 10:53
You can use to_timedelta
pd.to_timedelta(df+':00') Out[353]: 1 10:53:00 2 12:17:00 3 14:46:00 4 16:36:00 5 18:39:00 6 20:31:00 7 22:28:00 Name: Time, dtype: timedelta64[ns]
