Introduction

Writing one liners are cool. Let's try some.

Installations and configuration

pip install devtools==0.7.0
pip install -U django==3.2.*

mkdir myproject && cd myproject && django-admin startproject config .

Also, you did the migration
python manage.py migrate

Hello world

python -c "print('hello world')"

Another example is as follows,

python -c "from datetime import datetime; print(datetime.now())"

# Now lets take looping example,

python -c "for i in range(10): print(f'{i} x {7} = {(i+1)*7}')"

# Now let's write this to a file

python -c "with open('myfile.txt','w') as myfile: myfile.write('Hello world')"

myfile.txt is created in same folder you run above command.

Django one liners

Print Timezone Now time with Django's default timezone
python manage.py shell -c "from django.utils import timezone; print(timezone.now())"

Create a new admin user with username and password
python manage.py shell -c "from django.contrib.auth import get_user_model; User=get_user_model(); a=User.objects.create(username='a'); a.set_password('a'); a.is_superuser=True; a.is_staff=True; a.save()"

Print a query list values
python manage.py shell -c "from django.contrib.auth import get_user_model; User=get_user_model(); print(User.objects.values_list())"

Print user count
python manage.py shell -c "from django.contrib.auth import get_user_model; User=get_user_model(); print(User.objects.count())"

Tested on Debian 11, Python 3.6
