Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "If you just have one or two settings, you can use the following pattern in your models.py file."

A block of code is set as follows:

# magazine/__init__.py
# -*- coding: UTF-8 -*-
from __future__ import unicode_literals
default_app_config = "magazine.apps.MagazineAppConfig"

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

# magazine/__init__.py
# -*- coding: UTF-8 -*-
from __future__ import unicode_literals
default_app_config = "magazine.apps.MagazineAppConfig"

Any command-line input or output is written as follows:

(myproject_env)$ python
>>> import sys
>>> sys.path

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "For example, we added a phone icon to the Phone field and an @ sign for the Email field".

Note

Warnings or important notes appear in a box like this.
