Python is known for its simplicity and readability, making it an excellent choice for beginners and experienced programmers alike. One of the fundamental concepts in Python programming is looping over sequences such as lists, tuples, and strings.

This article will walk you through how to do this effectively and efficiently. By the end, you’ll have a solid understanding of looping over sequences in Python.

What are Sequences?

In Python, sequences refer to ordered collections of items, which can be either homogeneous or heterogeneous. The most common types of sequences include lists, tuples, and strings. These data structures allow us to store multiple values in a single variable, enabling us to manipulate and process them more efficiently.

Lists

A list is a mutable sequence type in Python. It can contain any number of elements, including different data types. Here’s an example of creating and printing a list:

my_list = ['apple', 'banana', 'cherry']
for fruit in my_list:
print(fruit)
