The following code gives the error ValueError("time data '2023-03-16T21:30:00.0000000Z' does not match format '%Y-%m-%dT%H:%M:%S.%fZ'") What is wrong?
date_string = '2023-03-16T21:30:00.0000000Z'
day_of_month_in_result = datetime.strptime(date_string, '%Y-%m-%dT%H:%M:%S.%fZ').day
print(day_of_month_in_result)
