Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "You can deactivate your environment at any time with the deactivate command."

A block of code is set as follows:

from django.contrib import admin
from .models import Post

admin.site.register(Post)

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

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'blog.apps.BlogConfig',
]

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

$ python manage.py startapp blog

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Fill in the form and click on the SAVE button."
