How to calculate the number of days in each month in python

Calculating the number of days in each month using Python requires importing the calendar module and using its monthrange function to get a tuple containing the day of the week for the first and last days, and the number of days in the month. Then, you can print the number of days in that month. For example, the number of days in April 2023 is calculated to be 30 days.
