# 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 swappingn”,“a=”,a,“b=”,b)

a,b=b,a

print(“Values after swappingn”,“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 swappingn”,“a=”,a,“b=”,b)

a=a+b

b=a-b

a=a-b

print(“Values after swappingn”,“a=”,a,“b=”,b)

**Output:-**

a=2

b=3

Values before swapping

a= 2 b= 3

Values after swapping

a= 3 b= 2
