This Python script performs a basic swapping operation between two integer variables, `x`

and `y`

.

```
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 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
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
```

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 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.
