Understanding how to configure INSTALLED_APPS is a basic skill for Django developers working on real projects.

1

Create the initial INSTALLED_APPS list

Create a list called INSTALLED_APPS with these exact strings: 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes'

Django

# Create the INSTALLED_APPS list with three default apps
# Your code here

Need a hint?

Use square brackets [] to create a list and include the exact app names as strings.

2

Add a custom app name variable

Create a variable called custom_app and set it to the string 'myapp'

Django

INSTALLED_APPS = ['django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes']
# Create a variable custom_app with value 'myapp'
# Your code here

Need a hint?

Assign the string 'myapp' to the variable custom_app.

3

Add the custom app to INSTALLED_APPS

Update INSTALLED_APPS by adding the custom_app variable as a new item using list concatenation

Django

INSTALLED_APPS = ['django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes']
custom_app = 'myapp'
# Add custom_app to INSTALLED_APPS using list concatenation
# Your code here

Need a hint?

Use INSTALLED_APPS = INSTALLED_APPS + [custom_app] to add the custom app as a list item.

4

Add the final app to INSTALLED_APPS

Add the string 'django.contrib.sessions' to the INSTALLED_APPS list using the append() method

Django

INSTALLED_APPS = ['django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes']
custom_app = 'myapp'
INSTALLED_APPS = INSTALLED_APPS + [custom_app]
# Add 'django.contrib.sessions' to INSTALLED_APPS using append()
# Your code here

Need a hint?

Use INSTALLED_APPS.append('django.contrib.sessions') to add the app at the end of the list.
