# Python Calendar Module

To use the Python calendar module, you can follow these steps:

### Step 1: Importing the Calendar Module
To import the calendar module in Python, use the following code:
“`python
import calendar
“`

### Step 2: Exploring the Contents of the Calendar Module
After importing the calendar module, you can explore its contents by using the `dir()` function. Here is an example:
“`python
dir(calendar)
“`
This will display a list of all the functions and attributes available in the calendar module.

### Step 3: Finding Names Containing ‘leap’ in the Calendar Module
If you want to find the names in the calendar module that contain the string ‘leap’, you can use the following list comprehension:
“`python
[x for x in dir(calendar) if ‘leap’ in x]
“`
This will give you a list of names containing ‘leap’.

### Step 4: Using the isleap Function
The `isleap(year)` function in the calendar module is used to determine if a given year is a leap year or not. You can check its usage by using the `help()` function like this:
“`python
help(calendar.isleap)
“`
This will provide you with information on how the function works.

### Step 5: Checking if a Specific Year is a Leap Year
To check if a specific year, for example, 2077, is a leap year or not, you can call the `isleap(year)` function with the year as an argument. Here is an example:
“`python
calendar.isleap(2077)
“`
If the output is `True`, it means the year is a leap year. If it is `False`, then the year is not a leap year.

By following these steps, you can effectively use the Python calendar module for various calendar-related operations.
