How to Swap Two Numbers in Python?

Python – Swap Two Numbers

To swap two numbers, say a,b , in Python, you can use assignment operator as shown below:

a,b = b,a

Thats it. Now b holds the original value of a. And a holds the original value of b. Let use see an example.

Example

In this example, we take two variables holding numbers. Then we swap the data in those variables.

a = 5
b = 45

a,b = b,a

print('a:',a)
print('b:',b)

Output

a: 45
b: 5

Summary

In this tutorial of Python Examples, we learned how to swap two numbers, using assignment operator.
