Last update on December 21 2024 07:27:37 (UTC/GMT +8 hours)

Write a Python program to create 12 fixed dates from a specified date over a given period. The difference between two dates is 20.

Sample Solution:

Python Code:

# Import the datetime module
import datetime

# Define a function named every_20_days that takes a date object (date) as input
def every_20_days(date):
    # Print the starting date
    print('Starting Date: {d}'.format(d=date))
    # Print a message indicating the next 12 days
    print("Next 12 days :")
    # Execute a loop that repeats 12 times
    for _ in range(12):
        # Add 20 days to the current date
        date = date + datetime.timedelta(days=20)
        # Print the resulting date
        print('{d}'.format(d=date))

# Define a date object representing August 1, 2016
dt = datetime.date(2016, 8, 1)

# Call the every_20_days function with the specified date object
every_20_days(dt)

Output:

Starting Date: 2016-08-01                                                                                     
Next 12 days :                                                                                                
2016-08-21                                                                                                    
2016-09-10                                                                                                    
2016-09-30                                                                                                    
2016-10-20                                                                                                    
2016-11-09                                                                                                    
2016-11-29                                                                                                    
2016-12-19

2017-01-28                                                                                                    
2017-02-17                                                                                                    
2017-03-09                                                                                                    
2017-03-29                 

Explanation:

In the exercise above,

• The code imports the "datetime" module.
• Define the function:
• It defines a function named "every_20_days()" that takes a date object (date) as input.
• Within this function,
• It prints the starting date passed to the function.
• It prints a message indicating the next 12 days.
• It executes a loop that repeats 12 times.
• Inside the loop, it adds 20 days to the current date (date) using the "timedelta()" function from the "datetime" module.
• It prints the resulting date.
• Initializing the date object:
• It initializes a date object 'dt' representing August 1, 2016.
• Call the function:
• It calls the "every_20_days()" function with the specified date object 'dt' as an argument.
