Day 3

Getting Started

Y ou will run the first Python script, hello world.py, in this chapter. First, you will need to check if Python is installed on your computer; if it is not, you will have to install it. You can also need a text editor for your Python programs to work on. Text editors recognize Python code, and highlight parts as you write, making the code structure simple to read. Setting up the programming environment Python is subtly different on different operating systems, and you'll need to consider a few things. Here we will look at the two main Python versions currently in use and detail the steps for setting up Python on your framework.

Python 2 and Python 3

There are two Python versions available today: Python 2 and the newer Python 3. Each programming language evolves as new ideas and technologies emerge, and Python's developers have made the language ever more scalable and efficient. Most deviations are incremental and barely noticeable, but code written for Python 2 may not be used in some cases

Function properly on installed Python 3 systems. Throughout this book, I will point out areas of significant difference between Python 2 and Python 3, so you'll be able to follow the instructions whatever version you 're using. Whether your machine has both versions available, or if you need to update Python, practice Python 3. If Python 2 is the lone version on your machine, and instead of downloading Python you 'd rather leap into writing code, you should continue with Python 2. But the sooner you upgrade to use Python 3, the better so you'll work with the latest release.

Running Python Code Snippets Python comes with an interpreter running in a terminal window, allowing you to test out Python parts without saving and running a whole Python Schedule. You'll see fragments throughout this novel, which look like this:

u >>> print("Hello Python interpreter!")
