Python Tutorial For Beginners: A Comprehensive Guide (2021)


The Python tutorial for beginners teaches all the Python concepts explaining what exactly Python is.

Python is a free-to-use and open-source programing language. So all that you need to do is to install Python and begin to work on it. You are also free to contribute your Python code to the community.

Python is a language that is cross-platform compatible. This means that you can install and then run Python on various operating systems. It could be on Mac, Windows, or Linux. Python will run on all of these seamlessly.

A python is also an efficient tool for visualization. It offers libraries like bokeh, seaborn, and matplotlib that help create amazing visuals. Here, we’ll walk you through the basics of Python Tutorial for Beginners.

In this article let us look at:

  1. Why learn Python?
  2. Career Opportunities
  3. Python Installation
  4. Variables in Python
  5. Data Types in Python
  6. Exception Handling

1. Why learn Python?

  • The main reason why developers learn Python is because it is simple and easy to learn this language. In comparison to the other languages like Java and C Python has a very easy syntax which makes it simple to use. There is also no need for a semicolon in the end.
  • Python just needs a single line but if it is Java then the same code will need many lines.
  • Another reason why one should learn Python is because Python opens up many career opportunities. This is something that we will be discussing in the next section.
  • There is a large open-source community in Python. If you start to work on any Python project and get stuck up then this is not at all a trouble. It is because Python has a huge community that is always there to help. In case you face any queries all that you need to do is to get help from the Python community members.

2. Career Opportunities

Let us now understand the various career opportunities that open up for you when you learn Python. Python professionals have a lot of demand in the IT industry. Whether it is a startup or a multi-national firm, they need to use Python to run various applications. So if you know Python and have taken the relevant Python tutorial for beginners then you will be sought after in varied domains like cloud infrastructure, machine learning, testing, website designing, etc.

3. Python Installation

What point is a python tutorial for beginners if we don’t address this; It could be a pain to install any programming language but not when you are using Python. Here is the step-by-step approach of how to install Python.

  • Go to the website
  • Click on the tab where you see downloads and choose the operating system that you have to use and the version of Python.
  • Now you have installed Python and you can go ahead and start programming

Installing Python is thus a cakewalk and can be done by anyone.

4. Variables in Python

A variable is nothing but a temporary space for storage and you can keep changing the values here. You will learn this in the Python tutorial for beginners.

Suppose you have a basket and you store an apple in it. After a while, you remove the apple and then place a banana here instead. After a few more moments you take out the banana and place a mango in its place.

The basket here is the variable that stores values that can keep changing.

Now that you know what variables are let us see how Python lets you assign a value to the variable. The assignment (=) operator is used to assign the value to a variable in Python. You can store a numerical value to the variable and then store a string value to it.

Now let us find out about the data types in Python.

5. Data Types in Python

Every variable has a data type and here we cover the varied data types that are used in python.

  • Numbers in Python

The number could be any integer, a complex number, or a floating-point number.

Python strings are anything written in a single or a double quote

  • Python Tuples

When you have a collection of many immutable objects in Python that is written within parenthesis then this is a Python Tuple. The Tuple elements could be of the same or different types of data

  • Python Lists

An ordered element collection is the Python list and this can contain many different types of data unlike the arrays

  • Python Sets

Python sets are the collection of unindexed and unordered items. Each element is unique in the set and it can contain duplicate values. Sets are used in mathematical calculations like differences, union, and intersection

  • Python Dictionary

 In an ordered data collection, the Python dictionary is stored as a key: value pair where the value can be of any kind and the key should not be mutable.

6. Exception Handling

The exception is any error or an abnormal condition that occurs when the program is executed. When there is an exception in the program then this causes the program execution to halt and this does not let the future instructions to be executed. These executions have to be handled for normal program execution.


Python is a popular language that is used for deep learning and machine learning. All the popular organizations today invest in Python to implement machine learning into their back end. It is thus recommended to attend the  Python tutorial for beginners.
