A list is one of the most commonly used data structures in Python.

Day 5: Python Syntax: Basic Concepts — List in detail

It is a collection of ordered, mutable (changeable), and heterogeneous elements.

Lists allow you to store multiple items in a single variable.

Lists are defined by square brackets [].

Characteristics of Lists:

1. Ordered: The items in a list have a specific order, and this order is maintained.
2. Mutable: You can change the elements in a list (add, remove, modify).
3. Heterogeneous: A list can store elements of different data types (e.g., integers, strings, or even other lists).

SYNTAX

list_name = [element1, element2, element3, ...]

Example of List in Python

1. Creating a List

# Creating a List
fruits = ["apple", "banana", "cherry", "orange"]

2. Accessing elements by index (starting from 0)

print(fruits[0])  # Output: apple
print(fruits[2])  # Output: cherry
