How to load edit run save text files py into an IPython notebook cell

Question

I ve recently moved over to using IPython notebooks as part of my workflow   However  I ve not been successful in finding a way to import  py files into the individual cells of an open IPython notebook so that they can edited  run and then saved  Can this be done   I ve found this in the documentation which tells me how to import  py files as new notebooks but this falls short of what I want to achieve   Any suggestions would be much appreciated

I have found it satisfactory to use ls and cd within ipython notebook to find the file  Then type cat your file name into the cell  and you ll get back the contents of the file  which you can then paste into the cell as code

EDIT  Starting from IPython 3  now Jupyter project   the notebook has a text editor that can be used as a more convenient alternative to   load edit save text files    A text file can be loaded in a notebook cell with the magic command  load   If you execute a cell containing    load filename py   the content of filename py will be loaded in the next cell  You can edit and execute it as usual   To save the cell content back into a file add the cell-magic   writefile filename py at the beginning of the cell and run it  Beware that if a file with the same name already exists it will be silently overwritten   To see the help for any magic command add a    like  load  or   writefile    For general help on magic functions type   magic  For a list of the available magic functions  use  lsmagic  For a description of any of them  type  magic name   e g    cd     See also  Magic functions from the official IPython docs

I have not found a satisfying answer for this question  i e how to load edit  run and save  Overwriting either using   writefile or  save -f doesn t work well if you want to show incremental changes in git  It would look like you delete all the lines in filename py and add all new lines  even though you just edit 1 line
