As a web developer, you’ll often encounter tasks that require repetition — whether it’s generating multiple HTML elements, processing user input, or manipulating data. That’s where loops come into play, offering a concise and efficient way to automate these repetitive actions. In this article, we’ll explore the world of loops in Python and how they can supercharge your web development workflows.

The Essence of Loops

At their core, loops are control structures that allow you to execute a block of code repeatedly, based on a specific condition. Python provides two primary types of loops: the for loop and the while loop.

The for Loop: Iterate Over Sequences

The for loop is ideal when you need to iterate over a sequence of items, such as a list, tuple, or string. Here's an example that generates a list of HTML list items:

fruits = ['apple', 'banana', 'cherry']
html_list = '<ul>\n'

for fruit in fruits:
html_list += f' <li>{fruit}</li>\n'

html_list += '</ul>'

print(html_list)

Output:

<ul>
<li>apple</li>…
