My Learning Journey
I started learning Python 4 to 5 years ago. I was interested in Machine Learning, particularly Computer Vision and Natural Language Processing. I did a lot of research on how and from where to start. I don’t want others to go through the same, so wrote this article. Here’s how I self-taught Python in just a couple of months.
Follow these steps exactly, and I guarantee you that they will help you advance your coding journey.
- I signed up for a Python Course on Codecademy and spent 1 hour a day. Doing just the course won’t help you, so keep reading below and follow the other steps as well! After going through each Module in the course, I watched YouTube videos by CS Dojo and Corey Schafer, both of them have outstanding videos.
- I then read a book called, "Python Crash Course" on the topic I learned from the Course and Videos (30 mins). This book is wonderful, it has everything from complete basics of Python to topics like Data Visualisation, APIs, Web Development (Django), etc.,
The book had 1-2 projects to practice. This book teaches you stuff that the course and videos don’t, so make sure to read everything. You will pace through the book easily because you already know a lot from the course and videos.
I later solved challenges from Hackerrank for 10 minutes to make sure that I understood the concepts that I learned. I spent around 2 hours a day. Not only that, but I took notes for everything so that I can go through everything once in a while (which was very helpful later).
After doing everything above, I started doing projects from the book Automating The Boring Stuff With Python (which is a fantastic book!).
- Later I started to learn Algorithms and Data Structures. I used the book called, Introduction to Algorithms. It’s a beginner’s friendly book but contains advanced stuff in later chapters. I spent around 1–2 hours a day and took a few months to complete. If you are into DevOps or SRE, you can skip this step. But it’s always good to know DSA. CS Dojo has a big playlist of videos on DSA. By the way, if you are interested in learning DSA, subscribe to my Newsletter on my Website – Narasimman Tech. I will be publishing many Data Structures and Algorithms articles with in-depth explanations.
- After learning Data Structures and Algorithms, I started my Machine Learning and Deep Learning journey, which is the reason I learned Python. Kaggle has free courses, like Python, Data Visualisation, ML, Neural Networks, and a lot. Check it out:

Career Specific Paths and Resources
Python is a multipurpose language. You can use it to automate in DevOps, Develop Web Apps, create CLI Applications, build Machine Learning Models, use it for Data Analysis, and more.
DevOps and SRE:
Why Python for DevOps?
Python is a popular programming language because of its simple syntax, which makes it easy to learn. Python comes pre-installed in almost all Operating Systems, so it's easy to run Python programs. It also has a massive collection of powerful libraries and a large community.
Resource and Tips:
I’m a DevOps Engineer by profession currently. I use Python Scripts to automate countless tasks daily. You don’t have to learn everything about Python, learn the basics that I mentioned above and some libraries. I read a wonderful book called, Python for DevOps: Learn Ruthlessly Effective Automation. This book teaches everything that you need to learn about Python for DevOps. I highly recommend this book to anyone interested in DevOps.
If you want to learn about DevOps tools and Technologies, follow me and subscribe to my newsletter because I will be publishing many articles about DevOps in the upcoming months. Also, take a look at my other article,
Python is very popular for web development. Companies like Google, Spotify, IBM, Instagram, and other big corporations use Python Frameworks to build their applications. Python offers many frameworks, among them there are two popular Python Frameworks - Flask and Django. Flask is a lightweight Framework whereas, Django is a full-stack Framework. I would suggest you learn Django first as it comes with numerous features and widely used than Flask.

Artificial Intelligence - Machine Learning, Deep Learning and Neural Networks
I started learning Python for Machine Learning and Deep Learning, and I spent a year building ML models. Python is the de-facto programming language for any AI technology. There are two popular Python Frameworks you might want to consider learning if you want to become an ML Engineer or Deep Learning Engineer:
If you don’t know, TensorFlow was created by Google, and now it is open-sourced. The official TensorFlow website has a learning path that you can follow. I enrolled in a Course on Coursera called TensorFlow Developer Professional Certificate. Additionally, I read a book called Hands-On Machine Learning with Scikit-Learn, Keras, and TensorFlow. This book is wonderful, you can easily understand concepts with basic python knowledge, and you have to know how to use NumPy, matplotlib, and pandas.
PyTorch was developed by Meta (formerly Facebook) and now it is open-sourced as well. One of the best resources is tutorials from the official website:
I would recommend you to read the book, Deep Learning with PyTorch by Eli Stevens, Luca Antiga, and Thomas Viehmann. This book is fantastic for advanced learners, tho’.
Learn any one of the Framework first and try to master it, it may take a couple of months or years, and you may learn the other Framework. If you are getting started, I would suggest you learn TensorFlow first, because it has many beginner-friendly resources and is a little easy to get started. Additionally, you can get an official Google TensorFlow Developer Certificate to verify your skills. It costs $100 to register for the exam. I used the same TensorFlow course from Coursera that I mentioned above to prepare for the exam:
Here’s a course if you are ready to learn advanced concepts in TensorFlow:
- Read the book Deep Learning by Aaron Courville, Ian Goodfellow, and Yoshua Bengio. This book is one of my favorite and the first book when I was getting started with ML and Deep Learning. This book starts with basics and covers advanced topics and algorithms. These books have everything to get started with AI.
- As I have mentioned above, Kaggle has many free courses to get started with Machine Learning and Deep Learning. https://www.kaggle.com/learn
- Learn a Database, start with Postgresql or MySQL and then MongoDB or Apache Cassandra and Graph-based database like Neo4j.
- Learn Data Visualization and Data Manipulation tools that I have mentioned above.
Data - Science, Analysis, and Engineering
Python is also popular among Data Scientists, Data Analysts, Data Engineers, and other Data related roles. There are numerous libraries and tools available like pandas for data manipulation and analysis, matplotlib, and seaborn for data visualization. I did a Data Engineering Professional course on Coursera by IBM 6 months ago:
It was nice and easy to get started. I sat for around 2 hours daily, and I completed the course in 3 months. This course is sufficient to get started, if you want to do a portfolio project, browse through this course:
I completed a Data Science course on Coursera 2 years back. This course is for someone who wanted to get started as a Data Scientist:
Data Analytics Course:
