What Is List in Python

 In Python, a list is a collection of ordered and changeable elements, allowing duplicates. It is one of the most versatile data structures in Python, as it can store any type of elements, including numbers, strings, and other objects.

A list in Python is defined using square brackets [] and the elements are separated by commas. For example:

css
fruits = ["apple", "banana", "cherry"]

Lists in Python are zero-indexed, meaning the first element has an index of 0, the second element has an index of 1, and so on. You can access an element in a list by its index, for example:

scss
print(fruits[0]) # Output: "apple"

Lists in Python are mutable, which means you can add, remove, or modify elements after the list has been created. For example:

python
fruits.append("orange") # add an element to the end of the listfruits.insert(1, "pear") # insert an element at a specific positionfruits.remove("banana") # remove an element by valuefruits[0] = "grape" # modify an element by index

Lists in Python also have many built-in methods, such as sort(), reverse(), pop(), and extend(), that allow you to perform various operations on the list.

In summary, lists in Python are ordered and changeable collections of elements, allowing duplicates. They are a powerful data structure that can store any type of elements and have many built-in methods for manipulating the list.
