Program of Python to Display Calendar

Mastering Python: Displaying Calendars with Ease

Introduction:

In the world of programming, versatility is key. Whether you're a seasoned developer or just starting your journey, knowing how to manipulate and display data in various formats is a fundamental skill. One such common task is displaying calendars, which can be incredibly useful in a wide range of applications. Fortunately, Python provides a straightforward way to accomplish this task, thanks to its built-in `calendar` module. In this blog post, we'll explore how to write a Python program to display calendars effortlessly.

Understanding the `Calendar` Module:

Before diving into code, let's take a moment to understand the `calendar` module. This module provides several functions to work with calendars, including functions to print calendars for a specific month or year, determine weekday names, and more.

Writing the Program:

Now, let's get our hands dirty and write a Python program to display calendars. Below is a simple script that prompts the user to enter a year and a month, and then displays the corresponding calendar:

import calendar

def display_calendar():

    year = int(input("Enter the year: "))

    month = int(input("Enter the month (1-12): "))

    # Validate input

    if month < 1 or month > 12:

        print("Invalid month input.")

        return

    # Display the calendar

    cal = calendar.month(year, month)

    print("\n", cal)

if __name__ == "__main__":

    display_calendar()

Explanation:

1. We import the `calendar` module, which provides the functionality we need.

2. We define a function `display_calendar()` to encapsulate the logic for displaying the calendar.

3. Inside the function, we prompt the user to enter the year and month.

4. We validate the input to ensure that the month entered is within the valid range (1-12).

5. Finally, we use the `calendar.month()` function to generate the calendar for the specified year and month and print it to the console.

Running the Program:

To run the program, simply save the code to a Python file (e.g., `display_calendar.py`) and execute it using a Python interpreter. Follow the prompts to enter the year and month, and voilà! You'll see the calendar displayed neatly in the console.

Conclusion:

In this blog post, we've explored how to write a Python program to display calendars effortlessly using the built-in `calendar` module. Armed with this knowledge, you can now incorporate calendar functionality into your Python applications with ease. Whether you're building a scheduling app, a task manager, or simply need to display dates in a user-friendly format, Python's `calendar` module has got you covered. Happy coding!
