Python: Get the date of the last Tuesday
19. Last Tuesday Finder
Write a Python program to get the date of the last Tuesday.
Sample Solution:
Python Code:
# Import the date class from the datetime module
from datetime import date
# Import the timedelta class from the datetime module
from datetime import timedelta
# Get the current date and assign it to the variable 'today'
today = date.today()
# Calculate the offset needed to go back to the most recent Tuesday
# This is done by finding the difference between the current weekday and Tuesday (1), and taking modulo 7
offset = (today.weekday() - 1) % 7
# Calculate the date of the most recent Tuesday by subtracting the offset from the current date
last_tuesday = today - timedelta(days=offset)
# Print the date of the most recent Tuesday
print(last_tuesday)
Output:
2017-05-02
Explanation:
In the exercise above,
- The code imports the "date" class and the "timedelta" class from the "datetime" module.
- Get current date:
- It retrieves the current date using the "date.today()" method and assigns it to the variable 'today'.
- Calculating Offset for most recent Tuesday:
- It calculates the offset needed to go back to the most recent Tuesday from the current date.
- This is done by finding the difference between the current weekday (today.weekday()) and Tuesday (1, where Monday is 0), then taking modulo 7 to ensure the offset loops back to Tuesday if the current day is Tuesday.
- Find the most recent Tuesday:
- It calculates the date of the most recent Tuesday by subtracting the calculated offset from the current date using "timedelta(days=offset)".
- Finally it prints the date of the most recent Tuesday.
