How to Determine Leap Years in Python: A Comprehensive Guide

Calculating Leap Years with Python

Determining whether a year is a leap year involves specific criteria that can be programmatically evaluated. A leap year is divisibly by four, except for years that are divisible by one hundred but not by four hundred.

One potential approach to this problem is to implement a custom function to check for leap years. However, when attempting to use such a function, you may encounter issues where the module returns None instead of the desired output.

A more robust and comprehensive solution is to leverage the built-in Python calendar module. The calendar.isleap function takes a year as input and returns a Boolean value indicating whether it is a leap year. This approach offers several advantages, including accuracy, reliability, and ease of implementation:

<code class="python">import calendar
print(calendar.isleap(1900))</code>

Utilizing this method, you can easily determine whether a given year is a leap year by importing the calendar module and using the isleap function. This approach provides a straightforward and efficient solution to your problem.
