เปิด python manage.py shell

The Django shell is an interactive Python session that already knows about your project, so you can test ideas live without writing a file. 🧪

Plain python can not import your models, because Django settings are not loaded. The shell command wires everything up for you first.

You launch it through manage.py, the same script you use for everything else. It loads settings, then drops you into Python.

Run the command in the folder that holds manage.py. From there Django can find your settings and apps with no extra setup.

Once it starts, you see the familiar Python prompt with three chevrons. Anything you type runs instantly and shows its result.

Because settings are configured, you can read project values right away. Try printing your DEBUG flag to confirm the shell sees them.

Now any model or utility is one import away. The shell is perfect for poking at code before you commit it to a file.

You are not limited to one-liners. Start a loop or function and the prompt switches to dots until the block is complete.

When you are done, type exit() or press Ctrl-D to return to your normal terminal. Nothing you typed is saved to disk.

Treat the shell as a scratchpad. It is ideal for experiments, but real changes belong in views, models, or scripts you can rerun.

One caution: queries hit your real database. Saving an object in the shell changes data for good, so be careful on production.

Why use the Django shell instead of plain python?

You learned that manage.py shell opens an interactive Python session with your project loaded, perfect for quick experiments before writing real code. 🎉
