Title: Python Tutorial - How to Swap Two Variables Without Using a Third Variable
Introduction:
Swapping the values of two variables is a common task in programming. While there are various methods to achieve this, one interesting approach is to swap the values without using a third variable. In this tutorial, we will explore a simple Python program to accomplish this task.
Code Example:
Explanation:
We define a function named swap_variables_without_third_var that takes two parameters (a and b) representing the variables to be swapped.
Inside the function, we print the values of a and b before swapping.
We use arithmetic operations to swap the values of a and b without using a third variable. The steps are as follows:
After the swapping process, we print the values of a and b to confirm the swap.
In the _main_ block, we take user input for the initial values of variables a and b and then call the swap_variables_without_third_var function with these values.
Note: This method relies on arithmetic operations and may not be suitable for all data types or situations. It's essential to consider potential issues, such as integer overflow for large values or precision loss for floating-point numbers.
