Forget all the fancy introductions, this book dives immediately into learning the Python programming language. You will know the Python programming language within a day, even if you have never programmed before. Every lesson is simply explained and shown, so you have a real hands on learning experience. At the end of every lesson there are practice activities, then a full answer code in case you get stuck. A fast-paced, no-nonsense guide to programming in Python.
Since Python is widely used in the world of data science and only growing in its popularity, it is an important tool for anyone getting started in data science. Learning Python as part of a wider data analytics skill set will make you a stronger candidate, as data analysts are expected to have a wide array of skills.
Many of today’s most successful tech companies use Python for the back-end of their website. Let’s take a look at a couple websites built using Python:
Instagram, the world’s biggest online photo-sharing app, uses Python on its backend.
Google is the most widely used search engine in the world with over 75% of the market share.
Longtime Google engineer, Alex Martelli, explained how Google got started using Python in their tech stack…
It all got started, I believe, because the very earliest Googlers (Sergey, Larry, Craig, …) made a good engineering decision: “Python where we can, C++ where we must.”
Spotify allows instant listening to specific tracks or albums with virtually no buffering delay.
The app was launched in 2008 and has since then has reached over 75 million paid subscribers.
Spotify’s backend consists of many interdependent services, connected by [its] own messaging protocol over ZeroMQ. Around 80% of these services are written in Python.
Netflix is the world’s leading internet television network with more than 33 million members
in 40 countries enjoying more than one billion hours of TV shows and movies per month.
Developers at Netflix have the freedom to choose the technologies best suited for the job. More and more, developers turn to Python due to its rich batteries-included standard library, succinct and clean yet expressive syntax, large developer community, and the wealth of third party libraries one can tap into to solve a given problem.
Uber, the ridesharing service, completes over 15 million trips daily.
At the lower levels, Uber’s engineers primarily write in Python, Node.js, Go, and Java. We started with two main languages: Node.js for the Marketplace team, and Python for everyone else. These first languages still power most services running at Uber today.
So, do you want to make some noise? Then lets learn some Python!
Python is a fun and powerful language to learn. In my book I hold your hand through the entire process, in a fun way, so that you will fully understand the basics of this amazing programming language.
