Python program to swap two variables using third variable

The python program to exchange the values of two variables is as follows:

 

# Owner : TutorialsInhand Author : Devjeet Roy

a = int(input("Enter a: "))
b = int(input("Enter b: "))
c = 0

print("Before swapping:")
print("a = {}, b = {}".format(a,b))

c = a
a = b
b = c

print("After swapping:")
print("a = {}, b = {}".format(a,b))

The output of the python program to exchange the values of two variables is as follows:

 

PS C:\Users\DEVJEET\Desktop\tutorialsInHand> python code.py
Enter a: 10
Enter b: 20
Before swapping:
a = 10, b = 20
After swapping:
a = 20, b = 10

Few important tips about this program

1. In this paradigm of swapping numbers, we reassign one number into the other variable such that we can swap it.

2. In the output, it is clearly seen that the numbers got interchanged.

3. The .format() is used to replace the braces with values of the variable passed to the function, in the string.
