The code starts by asking the user to input two values, x
and y
, and converting them to integers using the int
function. These values are then stored in the variables x
and y
respectively.
Next, the code prints the values of x
and y
before the swap using the print
function. The str
function is used to convert the values of x
and y
to string representations, so that they can be concatenated with the string literals in the print
statement.
The code then performs the swap by creating a temporary variable temp
and storing the value of x
in it. Then, the value of y
is assigned to x
, and finally the value of temp
(which is the original value of x
) is assigned to y
. This effectively swaps the values of x
and y
.
Finally, the code prints the values of x
and y
after the swap in the same manner as before.
This code demonstrates how to take user input, store values in variables, and perform a simple swap operation.
x = int(input("Enter a value for x: "))
y = int(input("Enter a value for y: "))
print("Before swapping:\nX: " + str(x) + "\nY: " + str(y))
# swapping numbers
temp = x
x = y
y = temp
print("After swapping:\nX: " + str(x) + "\nY: " + str(y))
Enter a value for x: 100
Enter a value for y: 200
Before swapping:
X: 100
Y: 200
After swapping:
X: 200
Y: 100

The code then performs the swap without using a temporary variable by using a series of arithmetic operations. Here’s how it works:
x = x + y
– This adds the values of x
and y
, and stores the result in x
.y = x - y
– This subtracts the original value of y
from the value of x
(which now contains the sum of x
and y
), and stores the result in y
.x = x - y
– This subtracts the new value of y
from the original value of x
, and stores the result in x
.The end result of these operations is that the values of x
and y
have been swapped without using a temporary variable.
Finally, the code prints the values of x
and y
after the swap in the same manner as before.
This code demonstrates an alternative way to perform a simple swap operation without using a temporary variable.
x = int(input("Enter a value for x: "))
y = int(input("Enter a value for y: "))
print("Before swapping:\nX: " + str(x) + "\nY: " + str(y))
# swapping numbers
x = x + y
y = x - y
x = x - y
print("After swapping:\nX: " + str(x) + "\nY: " + str(y))
Enter a value for x: 4
Enter a value for y: 8
Before swapping:
X: 4
Y: 8
After swapping:
X: 8
Y: 4
