20. Third Tuesday Tester

Write a Python program to test the third Tuesday of a month.

Sample Solution:

Python Code:

# Import the datetime class from the datetime module
from datetime import datetime 

# Define a function named is_third_tuesday that takes a date string (s) as input
def is_third_tuesday(s):
    # Convert the input date string to a datetime object using the specified format '%b %d, %Y'
    d = datetime.strptime(s, '%b %d, %Y')
    # Check if the weekday of the date is Tuesday (1) and the day of the month is between 15 and 21
    # This condition ensures that the date is the third Tuesday of the month
    return d.weekday() == 1 and 14 < d.day < 22

# Print the result of calling is_third_tuesday with different date strings
print(is_third_tuesday('Jun 23, 2015'))  # False
print(is_third_tuesday('Jun 16, 2015'))  # True
print(is_third_tuesday('Jul 21, 2015'))  # False

Output:

False                                                                
True                                                                 
True

Explanation:

In the exercise above,

The code imports the "datetime" class from the "datetime" module.
Define the function to check for the third Tuesday:

It defines a function named "is_third_tuesday()" that takes a date string (s) as input.
Within this function,

It converts the input date string to a "datetime" object using the "strptime()" method, specifying the date format as '%b %d, %Y'.
It checks if the weekday of the date is Tuesday (1) and if the day of the month is between 15 and 21. This condition ensures that the date is the third Tuesday of the month.

Finally, it prints the result of calling "is_third_tuesday()" function with different date strings.

For each date string, it prints 'True' if the date is the third Tuesday of the month and 'False' otherwise.
