Top 7 Free and Best DataCamp Courses to learn Python, SQL and Data Science

Hello guys, if you are looking for the best Datacamp courses to learn Python and SQL and become a Data Scientist in 2021, then you have come to the right place. In the past, I have shared the best udemy courses to learn Python and the best courses for data science. In this article, I will share both free and best Datacamp courses for Python developers and Data Science learners. Yes, you read it write, Datacamp also offers free courses and they are quality courses which you can take to learn at the skill on your own. If you don't know, Datacamp is a great platform to learn Data skills, and it has the best courses to learn Data skills like SQL, Data Science, and Python. 

They are like Codecademy for Data skills. They have interactive lessons, quizzes, video lectures, and creative exercises to teach key data skills, and that's why it's one of the best places to learn Python and SQL for data science. 

Data science is a big field where the student needs to have many programming languages like python language and R. Also, he needs to learn math and statistics, and they are mandatory to be a data scientist and maybe need to learn machine learning and deep learning to make predictions and all of these skills can be learned from one place called DataCamp.

Data nowadays is the core that keeps companies running and makes decisions based on the analysis of these data. This is the role of a data scientist. The DataCamp platform helps companies and individuals deal and work with data using many different tools and apply machine learning algorithms to these data. 






7 Free and Best Datacamp Online Courses to Learn Python, SQL, R and Data Science in 2021

Here is my list of best Datacamp courses people can take to learn essential tech skills like Python and SQL and become Data scientists in 2021. There is a lot of demand for Data Scientists and Backend engineers with Python and SQL, and these Datacamp courses will teach you those from scratch. 

From my 20 years of experience in tech, I can say that learning Python and SQL is the best decision of your life; unlike many frameworks and programming languages, Python and SQL have been around for more than 25 years, and there is still a great demand for them. Learning them is a good investment for life. 

The first three courses on this list are free and you can use them to learn Python, SQL, and R. Rest of them are not free because they are very specialized and high-quality courses and you would need a Datacamp subscription to access those courses, but you can always check the first chapter for free by using free Datacamp account


1. Introduction to Python [Free Course]

Python programming language is the language of the future since it is used in too many different industries like web development with Flask and Django frameworks also in data visualization with matplotlib library.

It also covers artificial intelligence using Tensorflow and Pytorch frameworks and Datacamp has created a course for learning this language from the beginning by understanding first the basics of this language like variables and data types, python lists, then moving to functions and importing packages and finally, working with arrays using NumPy.

The best thing about this Datacamp course is that its free, all chapters are free and you can access them by creating a free account.

2. Introduction to SQL [Free Course]

If you are looking to be a database administrator or a data scientist, or even a web developer, then you need to learn the SQL language, which is the language that is used to communicate with the database and extract and filter the data to use it. 

Datacamp has created an entire course teaching you the structure of the database and how to perform simple SQL queries, learn how to use comparison operators, use the aggregator functions, and finally, sort and group your results.

This is also one of the best free courses from Datacamp and if you are looking for free resources to learn SQL then you should check out this highly engaging SQL course on Datacamp.

3. Introduction to R [Free Course]

This is another free course from Datacamp to learn the R programming language for beginners.

 Data scientists need to learn maths and statistics to work with data and perform analysis, so alongside learning python, they also need to learn the R language, which is considered easy to learn like python but used a lot in the statistics field and analysis and data visualization. 

DataCamp offers a course in the R language, starting by learning the basics like arithmetic and variables and vectors, then learning metrics and performing computation with them, and more.

4. Introduction to Deep Learning in Python

If you want to be an AI engineer or a data scientist, you should definitely learn deep learning used in many fields such as robots, self-driving cars, natural language processing, and more. 

DataCamp has created a course that teaches you these skills using the Python language and Keras library, starting with the basics of neural networks and their concepts like the activation function. Then, it will learn how to optimize your model. Later create a neural network with Keras and evaluate your model.

5. Introduction to Data Visualization with Matplotlib

Data visualization is where you can convert the data into plots and charts to understand more about your data in one picture. This skill is mandatory if you want to be a data scientist, data analyst, or even an AI engineer. 

DataCamp has created a course that teaches you this skill using Python and matplotlib. It starts by understanding the matplotlib interface, creating some plots and customizing them, plotting time-series data and bar charts, and statistical plotting.

6. Supervised Learning with scikit-learn

In supervised learning, you use labeled data to train your model and make prediction, so you have to learn machine learning if you are planning to be a data scientists and this course teach you how to perform this using the sci-kit-learn and starting by learning how to solve classification problems then moving to solve problems with regression. Later, learn how to evaluate your model and improve it.

7. Unsupervised Learning in Python

Unsupervised learning is another type of machine learning that you need to learn. Here, the model will analyze and cluster unlabeled datasets and be used in customer segmentation and grouping your data according to its similarity. 

DataCamp has created a course on unsupervised learning using the sci-kit-learn and scipy, starting by learning the clustering techniques and applying them to the stock market prices, then learning how to visualize hierarchy and learn the dimension reduction techniques more.
