i have a pandas dataframe series , how to transform '30-06-2022' to '2022-06-30' in pd.datetime in python in python

To transform a date string in the format '30-06-2022' to '2022-06-30' using pd.to_datetime in pandas, you can specify the format of the input date string using the format parameter. Here's an example:

main.py
import pandas as pd

# Original date string
date_string = '30-06-2022'

# Convert to datetime format
date = pd.to_datetime(date_string, format='%d-%m-%Y')

# Transform the date format
transformed_date = date.strftime('%Y-%m-%d')

print(transformed_date)
254 chars
13 lines

Output:

main.py
2022-06-30
11 chars
2 lines

In the above code, pd.to_datetime is used to convert the date string to a pandas datetime object. The format parameter is set to '%d-%m-%Y' to match the format of the input date string.

Then, strftime method is used to transform the date into the desired format '%Y-%m-%d'.

Note: Make sure to use the correct format codes in format and strftime to match the input and output date formats respectively.
