How to Swap in Python

In this article, we will learn to swap two variables in Python.

Method 1:

a = 10
b = 5

print("Value of a is {} and value of b is {}".format(a, b))

# swaping values

temp = a
a = b
b = temp

print("After swapping, Value of a is {} and value of b is {}".format(a, b))

Output:

Value of a is 10 and value of b is 5
After swapping, Value of a is 5 and value of b is 10

Method 2:

a = 10
b = 5

print("Value of a is {} and value of b is {}".format(a, b))

# swaping values

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

print("After swapping, Value of a is {} and value of b is {}".format(a, b))

Output:

Value of a is 10 and value of b is 5
After swapping, Value of a is 5 and value of b is 10

Method 3:

a = 10
b = 5

print("Value of a is {} and value of b is {}".format(a, b))

# swaping values

a, b = b, a

print("After swapping, Value of a is {} and value of b is {}".format(a, b))

Output:

Value of a is 10 and value of b is 5
After swapping, Value of a is 5 and value of b is 10
