Similar to other programming languages, Python has gone through a few iterations, otherwise known as versions. Before you can fully understand the possibilities of Python, you need to understand the different versions and know which version you are using. The different versions of Python roaming the world prompt many a beginner to wonder things like Why are there different versions of Python?

The Python standard library is basically all the stuff you get when you get the Python languages. That includes all the Python data types like string, integer, float, and Boolean. Every instance of those data types is actually an instance of a class defined in the Python standard library.For this reason, the terms type, instance, and object are often used interchangeably.

is any list of data items, separated by commas, inside square brackets. Typically, you assign a name to the Python list using an = sign, just as you would with variables. If the list contains numbers, then don't use quotation marks around them. For example, here is a list of test scores:scores = [88, 92, 78, 90, 98, 84]If the list contains strings then, as always, those strings should be enclosed in single or double quotation marks, as in this example: in your code after defining that list shows this on the screen.

Python supports the concept of anonymous functions, also called lambda functions. The anonymous part of the name is based on the fact that the function doesn't need to have a name (but can have one if you want it to). The lambda part is based on the use of the keyword lambda to define them in Python. Lambda is also the 11th letter of the Greek alphabet.

You can use the Python language to build neural networks, from simple to complex. For you to build a neural network, you first need to decide what you want it to learn. For this simple Python tutorial, put your eyes on a pretty simple goal: implement a three-input XOR gate. (That’s an eXclusive OR gate.) The table below shows the function you’re going to implement in table form.

Before you can get going here, make sure you have your Raspberry Pi computer set up and running on your monitor, keyboard, and mouse. If not, go do that now The next few paragraphs are going to be lots more fun with a computer to work with!The Raspberry Pi is the perfect platform to do physical computing with Python because it has a multiscreen environment, lots of RAM and storage to play with and all the tools to build fun projects.

The first thing to know about I2C is that every device on the I2C bus has an address. For example, an HDC1080 temperature and humidity sensor that you can easily make has an address of 0x40. What does the “0x” mean in this address? It means that the number that follows is in hexadecimal notation, base 16 instead of base 10 (our normal numbering system).
