28. 30 Days Before/After

Write a Python program to get the dates 30 days before and after today.

Sample Solution:-

Python Code:

# Import the date and timedelta classes from the datetime module
from datetime import date, timedelta

# Get the current date and convert it to ISO 8601 format
current_date = date.today().isoformat()

# Calculate the date 30 days before the current date and convert it to ISO 8601 format
days_before = (date.today() - timedelta(days=30)).isoformat()

# Calculate the date 30 days after the current date and convert it to ISO 8601 format
days_after = (date.today() + timedelta(days=30)).isoformat()

# Print the current date, 30 days before the current date, and 30 days after the current date
print("\nCurrent Date: ", current_date)
print("30 days before current date: ", days_before)
print("30 days after current date : ", days_after)

Output:

Current Date:  2017-05-06                                                                                     
30 days before current date:  2017-04-06                                                                      
30 days after current date :  2017-06-05

Explanation:

In the exercise above,

The code imports the "date" and "timedelta" classes from the "datetime" module.
Calculating dates:

It calculates three dates:

current_date: It retrieves the current date using the "date.today()" method, converts it to the ISO 8601 format using the "isoformat()" method, and assigns it to the variable 'current_date'.
days_before: It calculates the date 30 days before the current date using the "timedelta(days=30)" function to subtract 30 days from the current date, converts it to the ISO 8601 format using the "isoformat()" method, and assigns it to the variable 'days_before'.
days_after: It calculates the date 30 days after the current date using the "timedelta(days=30)" function to add 30 days to the current date, converts it to the ISO 8601 format using the "isoformat()" method, and assigns it to the variable 'days_after'.

Finally it prints the current date, the date 30 days before the current date, and the date 30 days after the current date using the "print()" function.
