Hi Matthias ipynb is what I was looking for. I noticed two small problems. (I am not sure where/how to report them)
1) You can not import functions that have doc strings in them. Here is the error msg File "<unknown>", line 13 """uses Gauss's method for summing integers http://wmueller.com/precalculus/advanced/hint4_3_6.html"""; ^IndentationError: unexpected indent 2) I needed to use import 'as'. I think the https://github.com/ipython/ipynb readme.md needs to be update. Here is an example import ipynb.fs.defs.myMathFunctions as mmf mmf.quickSum(5) many thanks On Thursday, April 13, 2017 at 7:17:45 PM UTC-7, Matthias Bussonnier wrote: > > Hi Andy, > > I would suggest to look at https://github.com/ipython/ipynb , which is > supposed to do what you want by walking the AST. > We need to polish it and advertise it more, feedback (and > contributions) would be welcome. > -- > Matthias > > On Thu, Apr 13, 2017 at 5:28 PM, Andy Davidson > <[email protected] <javascript:>> wrote: > > Hi > > > > I have a couple of python functions defined in one notebook that I would > > like to reuse in another.
