Many of us who are familiar with programming languages like C, C++ etc. will have an answer like “String is a collection or array of characters.”

Well in Python also, we say the same definition for String data type. String is array of sequenced characters and is written inside single quotes, double quotes or triple quotes. Also, Python doesn’t have character data type, so when we write ‘a’, it is taken as a string with length 1.

Python is an object-oriented language and almost every entity in Python is an object, which means that programmers extensively use classes and objects while coding in Python. Objects in Python are basically an encapsulation of Python variables and functions, that they get from classes.

A class is simply a logical entity that behaves as a prototype or a template to create objects, while an object is just a collection of variables and Python functions. Variables and functions are defined inside the class and are accessed using objects. These variables and functions are collectively known as attributes.

Before discussing slice notation, we need to have a good grasp of indexing for sequential types.

In Python, list is akin to arrays in other scripting languages(Ruby, JavaScript, PHP). It allows you to store an enumerated set of items in one place and access an item by its position — index.

Let’s take a simple example:

>>> colors = [‘red’, ‘green’, ‘blue’, ‘yellow’, ‘white’, ‘black’]

Here we defined a list of colors. Each item in the list has a value(color name) and an index(its position in the list). Python uses zero-based indexing. …
