Pandas to time delta with only hours minutes and seconds

Question

In my script i extract a excel that in one column called "Time" is dtype object, in that column there's a hour like so "14:00:00" i want to convert the column to_datetime but when i do this:

df['Time']=pandas.to_datetime(df['Time'],format='%H:%M:%S')

i adds the year month and day to it and i dont want that to happen and i also want to keep that column as a datetime so i can then subtract to another time and get the seconds. How can i pass it to datetime with only the hours minutes and seconds?

Answer 1

Use Series.dt.time :

df['Time']=pandas.to_datetime(df['Time'],format='%H:%M:%S').dt.time

For adding or subtracting time , you can do this:

pd.Timedelta(df.Time - t1).seconds / 3600.0

Answer 2

you can use timedelta :

df['Time'] = pd.to_timedelta(df['Time'])

---

To calculate minutes:

pd.to_timedelta(df.time).dt.seconds/60
