Lesson Excerpts

Welcome to Python This course is going to teach you the basics of Python, how it works, and what it's capable of.

Hello World, Outputs and Variables

What is Python? Python is a high-level and general-purpose programming language. It's used on a lot of apps, like Instagram, Pinterest, and even Dropbox.

Hello World, Outputs and Variables

It's designed to be capable and fast, but also to be teachable. It's a good choice for beginners as it's lightweight and readable.

Hello World, Outputs and Variables

Python is used in many different circumstances - especially for Data Science. Even the data from CERN's Large Hadron Collider in Geneva is processed by Python.

Video

Start the Python interpreter – Idle. This will show you something that looks like this. We can type Python commands in here and interact with them but this is not where we will do most of our programming

Hello World, Outputs and Variables

Enter the code: print(“Hello world!”) in the shell and press enter and you should get the above output. Next click on the File menu and select New File. This will open the Python Editor window with a new blank file.

Hello World, Outputs and Variables

In the new blank window, type the same code as before on the first blank line. Go to the Run Menu, and click on Run Module. Of course, this will give you the same output as before. The vast majority of the code you'll write will be in the file editor - unless stated otherwise we'll be working in here.
