Learn R, Data Science,python for Free – List of Free Courses

We are living in an era of open-source technologies. With open source becoming a talk of the past as now we have also entered the age where Anyone can learn Anything from Anywhere across the globe (The AAAs). With so many skills and jobs being created in the industry today, there is a clear gap between what we studied and what we are working on. To fill this gap is where the internet has a major role to play.

As we move ahead, we dive deep into the free courses out there to learn Python, R language and Data Science.

What are R and Python?

When comes to programming you already have heard about python as a popular language. Programming in R, which started as ‘r-project’ is language and an environment used extensively in statistical computing and graphics. Data science thrives on programming and modelling of the solution and is built and fine-tuned by programming. Many professionals prefer python and some R as programming. So, it is expected out of a Data scientist to have a tech-proficiency of any of the two languages.

Now let us explore how you can start this journey of learning these open-source technologies for free.

Free resources for Python:

1. Python Fundamentals for Beginners (Great Learning)

The Great Learning Academy offers a free online course by which one can get familiarised with python. This course is targeted at beginners. Detailed lectures have been provided, which are easy to comprehend making it easier for beginners to grasp. The quiz is provided at the end of the topic to gauge and consolidate the knowledge. One important thing here to note is it provides in-depth knowledge and hands-on experience on advanced concepts of python programming.

2. w3schools Python Tutorial

Well, this platform has way more than just python. They have exercises, examples and a bunch of tutorials ranging from some of the basic concepts to some of the advanced ones as well. What makes it more interesting is they have touched upon some of the popular python packages such as Numpy, Matplotlib, Scipy and Machine learning concepts as well. This will not guard you to a larger project but is a great launchpad.

3. The official Microsoft course on learning python is on Youtube.

This is one of the best resources on YouTube and is completely free.

If you are a visual learner, consider hitting this up. They give small exercises in the middle and go over the solutions in the next video. It might go a bit too fast in the beginning but it can become your primary resource easily.

4. Automate the boring stuff with python

Automate the boring stuff by a python! Is an online project which has a free book by the name. written by Al Sweigart this website has the whole readable copy of the book in hyperlinks. The best thing about this is it has touched upon the practicality of python as a language. With some cool examples of web scraping, sending email and text messages this book adds a ton of interest to the learners. The book also talks about the type of errors and has a good emphasis on debugging as well. Though this will cover the tip of the ice-burg getting to the many tips is what becomes important to many enthusiast learners and this book does the job well.

5. Python.org

Yes, last but not least we should not forget the core of python that is the documentation in python.org. This documentation is written by the people who made it and given an extremely detailed manner. The tutorial section in python.org has different levels classification as Beginner, Moderate, Advanced and General. This will help everyone democratize the learning process and raise the learning curve to rise. It has also the examples given to add to the weightage. There is more to it, with the Audio Visuals and a Podcast on Python and about those who make python great. This might appeal a little to the beginner initially as it has poor UI as well.
