What is an example of an algorithm in Python?

I'll be happy to explain what an algorithm is and provide a simple example in Python!

An algorithm is a well-defined procedure that takes some input data, performs certain operations on it, and produces output based on those operations. In other words, it's a set of instructions that solves a specific problem or achieves a particular goal.

In computer science, algorithms are used to solve problems by processing data, making decisions, and producing results. They can be simple or complex, depending on the problem they're trying to solve.

Now, let's take a look at an example of an algorithm in Python!

Suppose we want to write a program that calculates the sum of all even numbers between 2 and 100 (inclusive). We can do this using a simple algorithm like this:

def sum_even_numbers():

total_sum = 0


for i in range(2, 101):


if i % 2 == 0: # check if number is even


total_sum += i


return total_sum


print(sum_even_numbers())

Here's how this algorithm works:

We initialize a variable total_sum to zero. We loop through all numbers from 2 to 100 (inclusive) using a for loop. Inside the loop, we check if each number is even by using the modulus operator %. If the remainder of dividing the number by 2 is zero, it means the number is even. If the number is even, we add it to our running total total_sum. After the loop finishes, we return the final value of total_sum, which represents the sum of all even numbers between 2 and 100.

This algorithm is a simple example of how we can use Python to solve a problem by following a set of steps. The code is easy to understand, and it produces the correct result: the sum of all even numbers between 2 and 100 is 2550.

In summary, an algorithm is a well-defined procedure that takes input data, performs operations on it, and produces output based on those operations. This Python example demonstrates how we can write an algorithm to solve a specific problem by following a set of steps.

I hope this helps!
