Introduction to Python Calendar Module
Python has a plethora of modules that can be used to make the development process faster and more efficient. One such module is the Calendar Module, which provides a range of functions for date manipulation and formatted data.
The Calendar Module is primarily used for displaying date-related information. This may include displaying a particular year, a month, a week, or a day.
With the help of this module, developers can easily manipulate dates and time, including time zones, daylight savings, and leap years.
Functions of Calendar Module
The Calendar Module offers an array of functions that are catered to date manipulation and formatted data. These include:
1.
Calendar(): This function returns a calendar for a specified year as an ASCII table. 2.
month(): This function displays the specified month of a given year.
3. isleap(): This function returns
True if the specified year is a leap year; otherwise, False is returned.
4. leapdays(): This function returns the number of leap years between two specified years.
5. weekday(): This function returns the day of the week on a particular date.
6. monthrange(): This function returns the first weekday and the number of days in the specified month.
calendar.month() function
The Calendar Module’s ‘month’ function is one of the most useful functions available. It can be used to display a single month’s calendar in a nicely formatted way.
This function takes two parameters: the year and the month. Usage of calendar.month() function
The calendar.month() function is used to display a particular month’s calendar.
This function is helpful for displaying the days of a month in an organized format, with weeks starting on a specific day.
Syntax and Example
The syntax for this function is simple. The first parameter is the year, and the second parameter is the month.
Syntax: calendar.month(year, month)
Example:
import calendar
# print the calendar of May 2021
print(calendar.month(2021, 5))
In this example, we are importing the Calendar module, and then using the month() function to display the May 2021 calendar. The output of this code will be:
May 2021

This is a simple and easy-to-read calendar display that provides an overview of the month. Additionally, the function can be used to display any month in any year, making it a versatile tool for developers.
Conclusion
The Calendar Module is a powerful tool for Python developers. Its functions make date manipulation and formatted data easy, and the month() function, in particular, is useful for displaying a nicely formatted calendar for a specific month.
By using the calendar module’s functions, developers can easily handle date and time operations, making their work more efficient. With its simplicity and versatility, the Calendar Module is a must-have for any Python developer.
3) calendar.calendar() function
The `calendar.calendar()` function is a built-in module in Python that is primarily used for displaying an entire year’s calendar in a nicely formatted way. Usage of calendar.calendar() function
This function is useful for printing out all the months of a year in a well-organized and formatted way.
Generally, this function is used when you need to display the calendar of an entire year.

The `calendar.calendar()` function takes one parameter, which is the year. Following is the syntax for the calendar() function.
Syntax: `calendar.calendar(year,w=2,l=1,c=6)`
Here is an example of how to use this function in Python:
“`python
import calendar
cal = calendar.calendar(2022)
print(cal)
“`
In this example, we are importing the Calendar module, and then using the `calendar()` function to display the calendar for the year 2022. The output of this code will be:
