Write a program in Python to split the date column into day, month, year in multiple columns of a given dataframe

Assume, you have a dataframe and the result for a date, month, year column is,

      date  day  month  year 0 17/05/2002 17   05    2002 1 16/02/1990 16   02    1990 2 25/09/1980 25   09    1980 3 11/05/2000 11   05    2000 4 17/09/1986 17   09    1986

To solve this, we will follow the steps given below −

Solution

• Create a list of dates and assign into dataframe.

• Apply str.split function inside ‘/’ delimiter to df[‘date’] column. Assign the result to df[[“day”, “month”, “year”]].

Example

Let’s check the following code to get a better understanding −

import pandas as pd df = pd.DataFrame({       'date': ['17/05/2002','16/02/1990','25/09/1980','11/05/2000','17/09/1986']    }) print("Original DataFrame:") print(df) df[["day", "month", "year"]] = df["date"].str.split("/", expand = True) print("\nNew DataFrame:") print(df)

Output

Original DataFrame:      date 0 17/05/2002 1 16/02/1990 2 25/09/1980 3 11/05/2000 4 17/09/1986 New DataFrame:       date  day  month year 0 17/05/2002 17    05 2002 1 16/02/1990 16    02 1990 2 25/09/1980 25    09 1980 3 11/05/2000 11    05 2000 4 17/09/1986 17    09 1986
