How can I square each number in a list of Integers using Python?

There is a particular scenario where I have a list of Integers and I want or need to square each number in the list by using the Python programming language. How can write a function square_number which would take a list of Integers numbers as Input and would help in returning a new list where each element is the square of the corresponding element from the input list? 

Answered by Ella Clarkson

 In the context of the Python programming language, you can square each number in a list of Integers by using the Python programming language by defining the function that would use the list comprehension and the exponential operator (**).


Def square_numbers(numbers):
    “””
    Squares each number in the input list using list comprehension.
    Args:
    Numbers (list of int): Input list of integers.
    Returns:
    List of int: List where each element is the square of the corresponding element in `numbers`.
    “””
    Squared_numbers = [x**2 for x in numbers]
    Return squared_numbers

Explanation

Functional definition

The functions square_numbers would take one parameter number, which is expected to be a list of the integers.

List comprehension

The list comprehension [x**2 for X in numbers] would Integrate through each element X in the input list numbers and would compute the X**2 which is the square of X.

Return value

The function would return squared _ numbers which would be a new list where each element would be the square of the corresponding element from the input list of numbers.

Here is the example usage given:-

# Example usage of the function
Input_list = [1, 2, 3, 4, 5]
Output_list = square_numbers(input_list)
Print(output_list) # Output: [1, 4, 9, 16, 25]

This above approach would effectively square each number in the given or input list by using the Python programming language’s exponential operator (**) within a list of comprehension, demonstrating proficiency in the basics of Python syntax and list operations.

Here is the Java-based approach given:-

Import java.util.Arrays;
Public class SquareNumbers {
    // Method to square each number in the input array
    Public static int[] squareNumbers(int[] numbers) {
        // Create a new array to store the squared values
        Int[] squaredNumbers = new int[numbers.length];
        // Iterate through each element in the input array
        For (int I = 0; I < numbers xss=removed xss=removed xss=removed>
