[python] How to load/edit/run/save text files (.py) into an IPython notebook cell?

To write/save

%%writefile myfile.py

  • write/save cell contents into myfile.py (use -a to append). Another alias: %%file myfile.py

To run

%run myfile.py

  • run myfile.py and output results in the current cell

To load/import

%load myfile.py

  • load "import" myfile.py into the current cell

For more magic and help

%lsmagic

  • list all the other cool cell magic commands.

%COMMAND-NAME?

  • for help on how to use a certain command. i.e. %run?

Note

Beside the cell magic commands, IPython notebook (now Jupyter notebook) is so cool that it allows you to use any unix command right from the cell (this is also equivalent to using the %%bash cell magic command).

To run a unix command from the cell, just precede your command with ! mark. for example:

  • !python --version see your python version
  • !python myfile.py run myfile.py and output results in the current cell, just like %run (see the difference between !python and %run in the comments below).

Also, see this nbviewer for further explanation with examples. Hope this helps.
