Write a python program to swap two numbers.

There are three method to swap the value of two numbers in the python :

 Method 1:-

a=int(input("a="))

b=int(input("b="))

print("Values before swapping=","a=",a,"b=",b)

temp=a

a=b

b=temp

print("Values after swapping=","a=",a,"b=",b)

Output:-

a=2

b=3

Values before swapping

a= 2 b= 3

Values after swapping

a= 3 b= 2

Method 2:-

a=int(input("a="))

b=int(input("b="))

print("Values before swapping\n","a=",a,"b=",b)

a,b=b,a

print("Values after swapping\n","a=",a,"b=",b)

output:-

a=2

b=3

Values before swapping

a= 2 b= 3

Values after swapping

a= 3 b= 2

Method 3:-

a=int(input("a="))

b=int(input("b="))

print("Values before swapping\n","a=",a,"b=",b)

a=a+b

b=a-b

a=a-b

print("Values after swapping\n","a=",a,"b=",b)

 Output:-

a=2

b=3

Values before swapping

a= 2 b= 3

Values after swapping

a= 3 b= 2
