python pandas: split string into date and time in datetime format

Question

I have a field in my dataframe df, labeled date, but after testing it a lot, I figured out that it is a string and not a date format.

Transaction_id | Date
ABC              4/1/2016 9:13:58 PM
CDE              10/3/2015 10:12:25 AM

I need to split the Date column up into Date & time and I want them to be in datetime format. I don't know how to do this with regex, since the lengths are different.

Output:

Transaction_id | Date                    | Date2       | Time            
ABC              4/1/2016 9:13:58 PM       04/01/2016    21:13:58
CDE              10/3/2015 10:12:25 AM     10/03/2016    10:12:25

Answer 1

Note that I placed a errors='coerce' to handle non-sensical date data.

date2 = pd.to_datetime(df.Date, errors='coerce')

df.assign(Date2=date2.dt.date, Time=date2.dt.time)

  Transaction_id                   Date       Date2      Time
0            ABC    4/1/2016 9:13:58 PM  2016-04-01  21:13:58
