The document introduces IPython and its notebook, highlighting its evolution from a simple interactive Python interpreter to an extensive tool for scientific computing with features like code execution, rich text integration, and collaboration. It provides installation instructions and usage tips for both IPython and the notebook interface, detailing how to leverage their functionalities for tasks like debugging and teaching. Additionally, it notes a grant received from the Alfred P. Sloan Foundation to enhance the development of IPython notebook for collaborative scientific work.
![Hands On IPython
- Shell
$ ls, pwd, !vim
- Code completion
$ import os
$ os.[press tab]
- Introspection
$ os?
$ os??
- History
> use the key up and down
- Execute previous command
$ _i, _ii, _iii : Previous, next previous, next next previous input
- Load Code > %loadpy
- Traceback and Debugger %pdb](https://image.slidesharecdn.com/introductiontoipythonnotebook-130207051314-phpapp02/85/Introduction-to-IPython-Notebook-6-320.jpg)
![Notebook - Django Extension
Notebook is not only for Physicists !!!
- Use it with Django:
https://github.com/django-extensions/django-extensions/pull/234
$ ./manage.py shell_plus --notebook
There is a little bug with the last IPython, that you can fix easily:
export PYTHONPATH=/home/areski/public_html/django/MyProjects/newfies-dialer
Add this in your settings.py:
IPYTHON_ARGUMENTS = [
'--ext', 'django_extensions.management.notebook_extension',
'--debug'
]](https://image.slidesharecdn.com/introductiontoipythonnotebook-130207051314-phpapp02/85/Introduction-to-IPython-Notebook-12-320.jpg)

- 2. Introduction to IPython - Fernando Perez started IPython in 2001, he wanted a better interactive Python interpreter - 259 lines of code, written in few hours https://gist.github.com/1579699 - Today: 78,481 lines of code & more than 100 contributors in the last 12 months http://www.ohloh.net/p/ipython
- 3. What is IPython? IPython is an interactive shell for Python ● additional shell syntax ● introspection ● tab completion ● rich history ● better debugging ● parallel computing
- 5. Install IPython http://ipython.org/ipython- doc/stable/install/install.html $ mkvirtualenv testipython $ pip install ipython - You could also use easy_install, but do you want to, really?
- 6. Hands On IPython - Shell $ ls, pwd, !vim - Code completion $ import os $ os.[press tab] - Introspection $ os? $ os?? - History > use the key up and down - Execute previous command $ _i, _ii, _iii : Previous, next previous, next next previous input - Load Code > %loadpy - Traceback and Debugger %pdb
- 7. Integration with your IDE - Vim https://github.com/ivanov/vim-ipython - Sublime Text https://github.com/iambus/SublimeIPython - TextMate http://wiki.ipython. org/Cookbook/Using_IPython_with_TextMate
- 8. NOTEBOOK
- 9. What is Notebook? A web-based application that can execute code and also contain rich text and figures, mathematical equations and arbitrary HTML - a web-based shell to an IPython - a mix of notes, code, html, images, video, ... - a great tool for debugging, teaching - has ability to save, edit and delete “notebooks”
- 10. Install Notebook Let's forget about easy_install, seriously? $ pip install ipython $ pip install pyzmq $ pip install tornado $ ipython notebook For some of the online examples : $ pip install numpy $ apt-get install libatlas-base-dev gfortran $ pip install scipy $ pip install matplotlib
- 11. Hands on Notebook $ ipython notebook - Cell-based execution workflow - Load previous code - Share IPython Notebook http://nbviewer.ipython.org/
- 12. Notebook - Django Extension Notebook is not only for Physicists !!! - Use it with Django: https://github.com/django-extensions/django-extensions/pull/234 $ ./manage.py shell_plus --notebook There is a little bug with the last IPython, that you can fix easily: export PYTHONPATH=/home/areski/public_html/django/MyProjects/newfies-dialer Add this in your settings.py: IPYTHON_ARGUMENTS = [ '--ext', 'django_extensions.management.notebook_extension', '--debug' ]
- 13. Conclusion - IPython Introspection, additional shell, tab completion, rich history, parallel computer, etc... - Notebook All the benefits of IPython on the web IPython received a Grant Sloan Foundation grant: IPython has been awarded a $1.15 million grant from the Alfred P. Sloan Foundation. This will support several core developers, allowing them to focus on building the IPython Notebook into a tool for open, collaborative, reproducible scientific computing. The Future is Bright !!!
