Creating the ATM app

Each app that we write in Django consists of a Python package, and we can use Django to automatically generate the basic app directory structure. One Django project can include many apps and configurations for a particular website, and an app can be included inside multiple projects. 

 Let's start by creating our own ATM app with the help of the following command:

(venv) [root@ip-172-31-95-213 django_app]# cd atmproject
(venv) [root@ip-172-31-95-213 atmproject]# python3.7 manage.py startapp atmapp

The following is the structure of an app:

(venv) [root@ip-172-31-95-213 atmproject]# tree atmapp
 atmapp
 ├── admin.py
 ├── apps.py
 ├── __init__.py
 ├── migrations
 │   └── __init__.py
 ├── models.py
 ├── tests.py
 └── views.py

In the console, the preceding structure will appear...
