If you want to start programming, or if you’re already a programmer and have been using Python for a while but have no idea what syntax is, then this cheat sheet is for you. It explains the basics of the language in plain language, including the difference between strings, lists, tuples, modules, classes and functions.

If you’re new to computers or programming at all, then the best way to learn is by doing. This cheat sheet is designed to help with that–to show you what Python looks like when you write it yourself.

The beauty of Python is that it can be learned in a few hours. There are no deep philosophies to learn, no magic formulas to memorize. All you have to do is learn a few key concepts and then write some code.

But if you’re new to the language, it’s not easy. When I first started learning it, there was nothing available that explained what Python was actually doing under the hood. The best books were like long lists of examples with little insight into how they fit together or what they meant.

I spent lots of time making half-baked attempts at reading through those books, but I never did get them down cold. It seemed like there were always more questions to answer than explanations to offer. I needed a cheat sheet for myself, so I wrote one for anyone else who had the same problem.

If you want to learn Python, you need a cheat sheet. It helps to have one when you’re learning new things. If you don’t have a cheat sheet when you are learning, you’ll waste a lot of time and get confused.

But the best cheat sheets aren’t just lists of things to do or steps to follow. They are references, which help you remember the things that are important to remember. I have seen too many people who wanted to learn programming but didn’t know why they needed it or what it might be useful for, or even that there was any reason in the first place for anyone to learn programming. They would ask their friends for advice, and the friend would say “You need Python.”

Python is useful for learning programming, because it is powerful and flexible enough to let you write programs that can do almost anything.

Python 3 is a good language to start with because it has a clear style and does a lot of the work for you. You won’t need to think about memory management or event handlers or Unicode support or all the other things that make programming in C, C++ and Java not just difficult but also awkward.

Python is an excellent language for beginners.

I’m not going to write a book about Python, because I don’t have time. So I’ll keep it simple.

I don’t want you to believe everything you read. You are smarter than that. In fact, you are much smarter than that. But if you look at the world with a skeptical eye and ask yourself, “How would I do this?” every now and then, you will be amazed at how much of what you think is true is actually wrong.

In some areas of life people have been taught that more means better. If they have been taught that, they are likely to think that the sky is closer than it is, and the grass is greener on the other side of the fence. They are likely to believe things they really should not believe. In others, people have been taught that less is better: less clutter, less noise, less hardness, less danger.

You know what both of these attitudes are? They’re Pythonic.
