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.

That syntax is a standard way to swap variables. However, we need to be careful of the order when dealing with elements that are modified and then used in subsequent storage elements of the swap. Using arrays with a direct index is fine. For example:

Apr 9, 2023 · The canonical way to swap two variables in Python is a, b = b, a Please note than this is valid whatever the "type" of a or b is (numeric, string, tuple, object, ...).

Dec 26, 2024 · Given two variables a and y, swap two variables without using a third variable. Examples: Store the sum of a and b in a (a = a + b). Get the original value of a, that is (sum – original value of b)and store it in b (b = a – b). Get the original value of b, that is (sum – original value of a)and store it in a (a = a – b).

Feb 7, 2024 · In this Python tutorial, I will explain the various methods to swap two numbers in Python using function, i.e., with arguments and return value, with arguments and without return value, without arguments and with return value, and without arguments and return value.

Swapping two numbers in Python is a fundamental operation that allows us to manipulate and rearrange data efficiently. In this article, we explored different methods for swapping two numbers: using a temporary variable, arithmetic operations, tuple unpacking, and XOR operations.

Mar 27, 2025 · In this tutorial, we covered multiple ways to swap two numbers in Python: Using a temporary variable; Without a temporary variable (arithmetic operations) Using tuple unpacking; Using XOR bitwise operator; Swapping in a function; Using collections like lists; Each method has its own advantages.

Apr 23, 2024 · Let’s see how it is possible to swap two numbers without using a temporary variable. In the above code, we first take the user input for both values and then exchange them together in one line like this: first_num, second_num = second_num, first_num.

Nov 7, 2021 · The simplest way to swap the values of two variables is using a temp variable. The temp variables is used to store the value of the fist variable (temp = a). This allows you to swap the value of the two variables (a = b) and then assign the value of temp to the second variable.

May 3, 2021 · We can use XOR swap only if both variables are integers. We can use Arithmetic Operators (+,- or *, /) only if both variables are integers or floating-point. We can use the method of the temporary variable or the comma operator in any case.
