So, these are the other best data science course for specific skills in the “Best Online Data Science Courses List”. Now, let’s see the step-by-step Data Science Roadmap with Python Programming-

Data Science Roadmap and Essential Skills

A data scientist requires an in-depth knowledge of the following skills-

1. Programming Skills
2. Statistics or Probability
3. Machine Learning
4. Multivariate Calculus and Linear Algebra
5. Data wrangling.
6. Data Visualization.
7. Database Management
8. BigData

Step 1- Learn Python First

If you are a complete beginner and don’t have Python Programming knowledge, then first learn Python

Step 2- Learn Math & Statistics

To learn data science, you should have a good understanding of Statistics and mathematics.

Step 3- Familiar with Python Libraries

Now, you need to know how to deal with data. And for this, Python has a rich set of libraries to perform data manipulation, analysis, and visualization.

Step 4- Brush Up on SQL Skills

You should know how to store and manage your data in a database. That’s why you should have an understanding of SQL.

Step 5- Learn Machine Learning Algorithms

At this step, you need to learn the basics of Machine Learning and the Types of Machine Learning algorithms( Supervised, Unsupervised, Semi-Supervised, Reinforcement Learning).

Step 6- Build Your First Machine Learning Model with scikit-learn

Now, you know how to perform data manipulation, analysis, and visualization. It’s time to predict something and find interesting patterns from the data. 

Step 7- Take Part in Data Science Competitions

Now it’s time to practice and check your command in Data Science. The best way to practice is to take part in competitions.

As a Data Science learner, you might have a question-“What is the Best Programming Language for Data Science?”. So, let’s see the best programming language for data science-

Best Programming Language for Data Science

To answer this question, I will compare the three most used programming languages for Data Science- Python, R, and Julia.

Python vs R vs Julia

Criteria	Python	R	Julia
Usage-	Python is a general-purpose programming language.	R is used for Data Analysis, Statistical Analysis, and Data Visualization.	Julia is used for Scientific computing.
Speed and Performance–	Python has average speed and performance.	R is a slow programming language.	Julia has high speed and performance similar to C language. Due to its high speed, there are approximately 13M downloads happening till May 2020.
Community-	Python has a huge community. That means, there is a huge Python community that can help you when you are stuck at some point.	R has also a huge community but not huge as Python.	Julia has a small community because it’s a new language. It might take 3 to 4 years to build a huge community.
Libraries available	Python has more than 200k libraries. This is quite huge.	R has approximately 15000 libraries.	Julia has approximately 3000 libraries.

So, this is the basic comparison between Python, R, and Julia. But the final conclusion has still not been drawn. For that, I will answer this question-

When to use Julia?

As I mentioned earlier, Julia has high speed and performance. So, If you have a huge data set, and you want a faster result, then only you should use Julia.

The next question that may come to your mind is, “Should I learn Julia or not?

The answer to this question depends upon your experience level. So I will explain both cases-

For Experienced-

If you are an experienced person, that means you have enough knowledge of Python or R. And you have done various data science tasks in Python or R, then you can learn Julia in order to enhance your skills. Knowledge of Julia will give you more privilege as a data scientist.

For Freshers-

If you are fresher and planning to start your career as a Data Scientist, then you shouldn’t start with Julia. For freshers, it is better to start with Python. Once you are familiar with Python and perform some data science projects in Python, then you can learn Julia.

Now, you got a clear answer for both cases. The next question is, “Python or R, Which should I use for Data Science?”

Python or R

If you are a beginner then the answer is Python. Why?. because Python is easy to understand language. You can perform all data science tasks easily with the help of Python. That means, starting your data science journey with Python.

As a fresher, you should have knowledge of only two programming languages- Python and SQL. That is enough for you. Once you cleared this level, then you can learn any other language.

If you are an experienced person, then knowledge of both (R and Python) is beneficial for you. Becoming an expert requires constant learning. The more knowledge you have, the more options you can create for yourself.

I hope, now you got an answer to all your questions. 

Now, you might have a question, “Which MOOC Platform is Best for Data Science?”.

Which MOOC Platform is Best for Data Science?

Let’s have a quick comparison between Coursera, edX, Udacity, Udemy, and DataCamp-

	Coursera	edX	Udacity	Udemy	DataCamp
Price	$39/month	Free to Audit, but for full material and certificate it cost around $50 to $300.	$399/month.	$10 to $199	Free account ($0), the Standard ($25 a month), or the Premium ($33.25 a month)
Mode of Learning	Self-paced videos with scheduled learning	A mix of self-paced or instructor-paced classes.	Most of the Udacity courses are self-paced.	Self-paced videos	Self-paced videos
Languages	Many Languages	English	Mostly English	Wide range of languages	English
Certificate Accreditation	Accredited certificates	Accredited certificates	Not Accredited	Not Accredited	Not Accredited
Course structure	Video Lectures, Quizzes, and assignments	Short videos, interactive learning exercises	Nanodegree programs and Free Online Courses	Video lectures	Video lectures
Best For-	Those who are looking for more detailed, structured, and credible courses from Top Universities.	Anyone who is looking to earn accredited certificates or university degrees.	Those who are looking for more real-world project-based advanced data science training.	Those who are looking for short courses that provide enough information in a short amount of time.	DataCamp is for those who are new in the field of Data Science and want to learn the basics of Data Science.
