Program to find leap Year or not in Python

2021-07-21T09:59:00.015+05:30

What is a Leap year ?

Generally we have 28 days in the month of February and overall 365 days in a year. But a leap year have 29 days in the month of February and overall 366 days in a year. For every four years we get a leap year.

Conditions to be a leap Year.

Year divisible by 4 is a leap year until it is not divisible by 100 (century year{year ends with 00} is not a leap year until it is divisible by 400, if it is divisible by 400 then it is a leap year.

Explanation :

For a non century year if year divisible by 4 then it is a leap year.
For a non century year if year not divisible by 4 then it is not a leap year.
If year is a century year then it is not a leap year.
Century year is said to be a leap year if it is divisible by 400 .

Input :

enter a year 2400

Output :

2400 is a leap year

Program to find leap Year or not in Python


#program to say leap year or not
year=int(input("enter a year "))
if year%4==0:
    if year%100==0:
        if year%400==0:
            print(year,"is a leap year.")
        else:
            print(year,"is not a leap year.")
    else:
        print(year,"is a leap year.")
else:
    print(year,"is not a leap year.")
    
#----method 2------using ternary operator---------#
year=int(input())
print("leap year"if (year%4==0) else "not a leap year")

Output :

enter a year 2400
2400 is a leap year.

Swaping two numbers | program | python solution

2021-07-04T06:16:00.005+05:30

Program for swapping of two numbers

Swapping refers to the exchange of two or more things.

Example:

a=5 , b=10

After swapping a becomes 10 and b becomes 5.

Explanation :

Read a and b value.
Use any of the below methods and get output

Method1:

We have very simple method in python i.e.,

a , b = b , a

Method2:

Using third variable or temporary variable ,

a = a + b b = a - b a = a- b

Method3:

Using Bitwise XOR (^),

a = a ^ b b = a ^ b a = a ^ b

Input :

a = 5

b = 10

Output :

a = 10

b = 5

PROGRAM IN PYTHON

#swapping of two numbers
a = 5
b = 10
a , b = b , a
#after swapping
print("a is",a,"b is ",b)

#method 2
a = a + b
b = a - b
a = a - b
print("a is",a,"b is ",b)

#method 2 --- using xor
a = a ^ b
b = a ^ b
a = a ^ b
print("a is",a,"b is ",b)

Output


a is 10 b is  5
a is 5 b is  10
a is 10 b is  5

Program to find leap Year or not in Python

What is a Leap year ?

Generally we have 28 days in the month of February and overall 365 days in a year. But a leap year have 29 days in the month of February and overall 366 days in a year. For every four years we get a leap year.

Conditions to be a leap Year.

Year divisible by 4 is a leap year until it is not divisible by 100 (century year{year ends with 00} is not a leap year until it is divisible by 400, if it is divisible by 400 then it is a leap year.

Explanation :

For a non century year if year divisible by 4 then it is a leap year.

For a non century year if year not divisible by 4 then it is not a leap year.

If year is a century year then it is not a leap year.

Century year is said to be a leap year if it is divisible by 400 .

Input :

enter a year 2400

Output :

2400 is a leap year

Program to find leap Year or not in Python

Printing Multiplication table in Python

Display Multiplication table in Python

Read an integer using input() function.

print(f"Multiplication table of {number} is")

Use for loop to iterate multiplication for 10 times.

print(number,"*",i,"=",number*i).

As a result we get the output as a multiplication table of number.

Input:

enter any integer : 5

Output :

5 * 1 = 55 * 2 = 105 * 3 = 155 * 4 = 205 * 5 = 255 * 6 = 305 * 7 = 355 * 8 = 405 * 9 = 455 * 10 = 50

Program to display multiplication table in python.

Output :
