Calendar module in python




This module is basically used to display a calendar of the current month or range of months.

The calendar module provides date range functionality in python.

This module is used to contain predefined functionality in the Python program, Python is so rich for predefined functionality. all predefine functionality has been defined under the module.

Example of Calendar Module in Python:-
import calendar

print(calendar.month(2014,3))
print(calendar.firstweekday())
if (calendar.isleap(2020)):
   print ("The year is leap year")
else :
   print ("The year is not leap year")
print (calendar.leapdays(1950, 2000)) 

print ("The calender of year 2018 is : ")  
print (calendar.calendar(2018, 2, 1, 6))        # Y, W,  no. of lines per week ,  No Of columns

ASSIGNMENT using Calendar?
1)  WAP to calculate the total age in year, month, and a day where the date of birth will be entered by the user?
Solution of this program by Shiva Sir:-
from datetime import date
a = date(date.today().year, date.today().month, date.today().day)
b = date(int(input("enter year")), int(input("enter month")), int(input("enter day")))
if(a.month>b.month):
 months = a.month - b.month
else:
 months = b.month - a.month  
years = a.year - b.year
if(a.day>b.day):
   days = a.day - b.day
else:
   days = b.day - a.day 
print('{0} years, {1} months, {2} days'.format(years, months, days))
2)  WAP to display before the day, after day when the user enters a number of days.
3)  WAP to create STOP watch when pressings s then start, p then pause and  e then end?

    from datetime import date

    print("##### Welcome to age calculator ######")
    birth_year = int(input("Enter your year of birth: \n"))
    birth_month = int(input("Enter your month of birth: \n"))
    birth_day = int(input("Enter your day of birth: \n"))

    current_year = date.today().year
    current_month = date.today().month
    current_day = date.today().day

    age_year = current_year - birth_year
    age_month = abs(current_month-birth_month)
    age_day = abs(current_day-birth_day)

    print("Your exact age is: ", age_year, "Years", age_month, "months and", age_day, "days")

Uncontrolled form input in React-JS

  Uncontrolled form input in React-JS? If we want to take input from users without any separate event handling then we can uncontrolled the data binding technique. The uncontrolled input is similar to the traditional HTML form inputs. The DOM itself handles the form data. Here, the HTML elements maintain their own state that will be updated when the input value changes. To write an uncontrolled component, you need to use a ref to get form values from the DOM. In other words, there is no need to write an event handler for every state update. You can use a ref to access the input field value of the form from the DOM. Example of Uncontrolled Form Input:- import React from "react" ; export class Info extends React . Component {     constructor ( props )     {         super ( props );         this . fun = this . fun . bind ( this ); //event method binding         this . input = React . createRef ();...
