Here is the code to convert transaction_time column to date and time columns: import pandas as pd # Assuming df is your DataFrame with 'transaction_time' column df['date'] = pd.to_datetime(df.transaction_time).dt.date df['time'] = pd.to_datetime(df.transaction_time.str.replace(r'\..*', '')).dt.time # If you want to move date and time back to the front of the columns columns = df.columns.to_list()[-2:] + df.columns.to_list()[:-2] df = df[columns] print(df) This code will convert the transaction_time column into two separate columns, date and time, using pandas’ to_datetime function with dt.
