This is a book (often) about code, so you need to setup your coding environment. Since you already know how to code a little, I assume you know how to use a text editor, change a file and run commands, and have Python 3.6 or later installed.

Get the code

For this part of the book, we have a single folder with all the example code.

It's available in GitLab: part1 example code or just download it in a zip file

Setup a virtual environment

Use your favourite tool, setup a virtualenv and activate it. If you have no idea what I mean, do this:

1$ cd code
2$ python -m venv venv
3$ source venv/bin/activate

After you run the source command, your prompt will say "venv". That means you are working in an isolated environment and when you install / uninstall python packages you are not breaking your system.

To go back to the real world, you can use the deactivate command.

Install dependencies

$ pip install -r requirements.txt

Check it worked

1$ python
2Looks good!

If it gives an error instead, there is a problem and we have to fix it.

You are now ready to move on to the real work. Have fun!
