21. Last Day Finder

Write a Python program to get the last day of a specified year and month.

Sample Solution:

Python Code:

# Import the calendar module
import calendar

# Define the year and month for which we want to find the number of days
year = 2015
month = 2

# Use the monthrange() function from the calendar module to get the number of days in the specified month
# The [1] index of the returned tuple contains the number of days in the month
print(calendar.monthrange(year, month)[1])

Output:

Explanation:

In the exercise above,

The code imports the "calendar" module.
Define Year and Month:

It defines variables 'year' and 'month' with the values 2015 and 2, respectively. These represent the year and month for which we want to find the number of days.

Calculating the number of days in the month:

It uses the "monthrange()" function from the "calendar" module to get information about the specified month (month) in the specified year (year).
The "monthrange()" function returns a tuple containing two values:

The first value is the weekday of the first day of the month (0 for Monday, 1 for Tuesday, etc.).
The second value is the number of days in the month.

By accessing the second value of the tuple ([1]), the code retrieves the number of days in the specified month.

Finally it prints the number of days in the specified month using "print()".
