Python Program to Swap Variables

Swap values using third variable

1# Python program to swap two variables
2a = 10
3b = 20
4
5temp = a
6a = b
7b = temp
8
9print("a:", a)
10print("b:", b)

Output

1a: 20
2b: 10

Swap Two Variables Without Using Third Variable

1a = 10
2b = 20
3
4# Use assignment operator to swap variable values
5a, b = b, a
6
7print("a:", a)
8print("b:", b)

Output

1a: 20
2b: 10

Using Arithimatic Operator to Swap Variables

1a = 10
2b = 20
3
4a = a + b
5b = a - b
6a = a - b
7
8print("a:", a)
9print("b:", b)

Output

1a: 20
2b: 10
