ThePython Interactive Shell is an interactive interpreter that can executePython commands.

You can invoke it from your default shell —zsh,bash,fish etc.:

$python# or for a specific python version$python3.9

Also you can run interactive shell with a module/file like below:

$python-i somefile.py

Use Case

Thanks python, however I can't say I enjoy your default shell. I need morecapable,colorful interactive shell likeIPython,bpython.

It's easy to achieve this inDjango. It's well documented indjango-shell:

# IPython$django-admin-i ipython# bpython$django-admin-i bpython

Well, how can we achieve it inPython?

Solution

Python's way is kind of similar; you invoke it with somemodule using-m flag:

ForIPython run:

$python-m IPython-i# with module/file$python-m IPython-i somefile.py

Forbpython run:

$python-m bpython-i# with module/file$python-m bpython-i somefile.py

NOTE
In order to be able to useIPython and/orbpython first you have to install them:

$python-m pipinstallipython$python-m pipinstallbpython

Yes, it's that easy and now we can take advantage of amazing features like below:

• In-line syntax highlighting
• Readline-like auto-complete with suggestions displayed as you type
• Expected parameter list for any Python function, etc.

Probably it would be better to have them as aliases:

# .aliasesaliaspi='python -m IPython -i'aliaspib='python -m bpython -i'

All done!
