Question

Write a program to swap two numbers without using a third variable.

Answer 1

Program:
#defining two variables
x = 5
y = 6

#printing the values before swapping

print("The values of x and y are",x,"and",y,"respectively.")

# Using 'multiple assignment' to swap the values
x,y = y,x

#printing the values after swapping
print("The values of x and y after swapping are",x,"and",y,"respectively.")

OUTPUT:
The values of x and y are 5 and 6 respectively.
The values of x and y after swapping are 6 and 5 respectively.
