Learning Python for Data Science: 7 Easy Tips for

Learning Python for Data Science can really go a long way in elevating your career potential, but at first – learning to code can seem scary for most. If that’s you, don’t worry – it can be done totally, without going back to school either.

In today’s article, I’m sharing my top 7 easy tips for learning python for data science.

Be sure to read to the end because that’s where I am going to share with you the very best way to take this new skill you’re developing and use it to start attracting clients and would-be employers.

As far as why I’m qualified to give advice on learning python for data science – through my partnership with LinkedIn learning, I have successfully educated over one million of their students on how to use python for data science. So, you could say I know a thing or two about python for data science.

If you’re new around here… Hi, I’m Lillian Pierson and I support data professionals in becoming world-class data leaders and entrepreneurs.

I broke the 7 tips down into 3 types: learning tips, practice tips, and lifestyle tips. Let’s start with learning tips:

There are many amazing places to learn both Python and data science for free on the internet. There are also hundreds of videos on YouTube. In all honesty, I can’t recommend any of them because I haven’t used any of them… When I learned data science – I mostly did so through low-cost online course and books.

You want to practice coding daily. That will help developyour computational thinking abilities.

WHAT. Computational thinking is an approach to problem solving that both a human and a computer can understand.

Free resource to help get you started: Google’s Exploring Computation Thinking curriculum 

One benefit of computational thinking is that it allows you to better understand how algorithms rely on data structures.

Data structures are ways in which data is arranged. A simple example of a data structure would be the ‘list’ or ‘array’ data types. A simple example of an algorithm would be a sorting algorithm, which, for example, can reshuffle an array so that it reads from lowest to highest value.

Using computational thinking helps you write efficient algorithms. Although Python comes with basic algorithms in place, it’s important to understand the logic behind what you’re doing if you want to master the basics. The same goes for Python’s data science libraries like scikit-learn, pandas, and scipy.

Free resource – you can learn anything you need to know about data structures and algorithms simply by going over to Tutorial Point.

Once you’ve mastered the basics, it’s time to learn about Git.

Git is a tool used for collaborative projects that allows multiple people to share files and make changes to code. 

Once you’re working on larger data science projects, you’ll need Git. 

When you’re using Git, you and other developers will be making changes to aremote repository.

Think of this like a text file on Google Drive that anyone can access and edit.

Your personal saved files are called alocal repository. Git compares the local and remote repositories and shows you what changes have been made.

Git also usescommits. Commits are points at which the developer knows the project is working. The developer can return to these points if something is amiss.

Think of commits as the quicksave function in a video game. If you die it’s no problem, you can start again from your last quicksave.

GitHub is a website that gives Git a user-friendly interface, and keeps track of these commits. It has other functions as well. For example, it allows users to:

This is a key stage in learning how to code, so don’t stick to the basics for too long. In this sort of logic-driven work, learning from your own mistakes is the best and most efficient way to learn.

Whatever you do on your laptop, there are systems that need improving and that can be automated using Python. Start creating solutions that help you in your daily work and you might end up stumbling onto something that others could use.

If you need a head start on ideas for ways you can use Python to begin automating your daily work, there is a course on Udemy called “Automate the Boring Stuff with Python.”

Practice on demo problems, learn from past competitors, compete in an active competition and make some money.

The sooner you start working through your problems, the sooner the basics will become second nature.

Now, I’m going to share with you what you can do to start your newly developed skills to attract would-be employers or clients.

Practice might not make perfect, but it sure does make things easier.

Practicing daily makes writing, understanding, and problem solving in the language easier. Think of any other language. If you’re reading, writing and communicating in it every day, it quickly becomes second nature.

Because Python was designed to resemble human language, treating it as such will make the learning-process easier. Using the language in this intuitive manner will also enhance your problem-solving ability and develop your computational thinking skills.

Keeping a record of your progress in the form of ablogor personal document is a good foundation for building a portfolio. 

It also allows you to apply new knowledge to previous problems, keeping all your projects at a similar level.

A new problem might force you to refine an algorithm used in an old project.

If you still have access to the old project, you can use this as an opportunity to rethink and refine your old code.

I know that first hand, because when I first learned data science back in 2012, I didn’t know python and I was completely open about the fact that I’m teaching myself data science and I’m not experienced – that this is just me recording my learning journey.

And within just a few months, IBM was already paying me to write for them. I got a job from the United Nations doing evaluation on this entire refugee camp and Syria. It just opened up so many opportunities in my career and all I did was just blog and document my learning process!

So, if you think you want to do python, and use python for data science in a career venture in the future, document it using a blog, a coding portfolio, YouTube, something like that.
