Python indexing of values in a list

Indexing is a fundamental concept in Python, and it's essential to understand how to access and manipulate individual elements in a list. Lists are ordered collections of items, and indexing allows you to retrieve and modify those items based on their position within the list. In this tutorial, we'll explore Python indexing of values in a list with code examples.
In Python, list indexing starts at 0, meaning the first element of a list is at index 0, the second element is at index 1, and so on. To access an element at a specific index, you can use square brackets [].
Python also supports negative indexing, where -1 represents the last element, -2 the second-to-last element, and so on.
Slicing allows you to extract a portion of a list. You specify a start index (inclusive) and an end index (exclusive) within square brackets, separated by a colon :.
You can change the value of a list element by assigning a new value to a specific index.
Remember that lists are mutable, so these changes directly affect the original list.
In conclusion, understanding list indexing and slicing is crucial for working with Python lists efficiently. You can use these techniques to access, manipulate, and extract elements from lists, making them a versatile data structure in Python.
