Write a program is python to swap two numbers.

Answer:

Source Code: Using a temporary variable

# Python program to swap two variables

x = 5

y = 10

# To take inputs from the user

#x = input('Enter value of x: ')

#y = input('Enter value of y: ')

# create a temporary variable and swap the values

temp = x

x = y

y = temp

print('The value of x after swapping: {}'.format(x))

print('The value of y after swapping: {}'.format(y))

Output

The value of x after swapping: 10

The value of y after swapping: 5

In this program, we use the temp variable to hold the value of x temporarily. We then put the value of y in x and later temp in y. In this way, the values get exchanged.

Source Code: Without Using Temporary Variable

In Python, there is a simple construct to swap variables. The following code does the same as above but without the use of any temporary variable.

x = 5

y = 10

x, y = y, x

print("x =", x)

print("y =", y)

If the variables are both numbers, we can use arithmetic operations to do the same. It might not look intuitive at first sight. But if you think about it, it is pretty easy to figure it out. Here are a few examples

Addition and Subtraction

x = x + y

y = x - y

x = x - y

Multiplication and Division

x = x * y

y = x / y

x = x / y

XOR swap

This algorithm works for integers only

x = x ^ y

y = x ^ y

x = x ^ y
