Indexing is a fundamental concept in programming, allowing you to access and manipulate individual elements within data structures like lists, strings, and arrays. In Python, indexing starts at 0, meaning the first element has an index of 0, the second has an index of 1, and so on. This tutorial will guide you through the basics of indexing in Python with code examples.
Let's start with a simple list:
To access a specific element, use square brackets and the index:
You can also modify elements by assigning a new value to a specific index:
Strings are sequences of characters, and you can access individual characters using indexing:
Negative indexing allows you to access elements from the end of a sequence. -1 represents the last element, -2 the second-to-last, and so on:
Understanding indexing is crucial for working with data structures in Python. Whether you're dealing with lists, strings, or other sequence types, mastering indexing will empower you to efficiently manipulate and retrieve elements. Practice using these concepts in your own projects to solidify your understanding.
