Question about SymPy live function def

[Comer Duncan]

Today I tried defining a function while in the SympyLive shell.  That is something like:

def f(x):

      return x

But when entered, I got a complaint.  So I changed the input method to shift-enter and got it to work (ie got the def to work). When using it with such as f(1) it returned the correct answer.  However, I am now writing some documentation on my local machine and when it is made it has no errors.  When I view the html of the new stuff I am writing which includes some example code with a def f(x):

in it, when executed in SymPy  Live from the html display of the new doc, I get a failure just when the new function is defined. So it does not parse the requested code as I want. It seem that when executing the doc code on SymPy Live the apparently needed shift-enter rather than the default enter is what is encountered. So for the unsuspecting user who reads the documentation and just wants to run it, there is a problem.  How to enable the correct behavior so the user will get the code executed properly and will not have to discover the workaround. I just want the code to work with no further bother from the user.  Can someone please clue me in?

Thanks.

Hello,

Could you please be more specific about the 'complaint'? If the input method is set to 'enter', then 'shift-enter' will create a newline without submitting the expression.

For the second part of your question: as I understand, your documentation contains a function definition, but when 'Run code block in SymPy Live' is pressed, it comes up with an error? In the documentation there are examples of functions being defined that work just fine (e.g. http://docs.sympy.org/latest/tutorial/simplification.html#example-continued-fractions) - perhaps you could see how that example is formatted. Without the error message I'm not quite sure what is wrong.

Hi David,

Thanks for the github suggestions. I will do that at some point.  Given your pointer in the doc, I now see that the solution to my problem when trying to run a given segment on SymPy Live was to replace '>>>' with '...'  when defining a function. It now works as desired.

Hello Comer,

You could fork the SymPy project on Github, create a new branch, push the changes to that branch, and share the URL with us on the mailing list. That way we can see what you have and comment on it.

Thank you,

Hi David,

How can I share my work in progress so you can see better what I am seeing?  So far the new documentation is a tutorial, i.e. is a file in the tutorial subdir.  I have not made a new git project, thinking that I would like to get the writing further along before submitting a pull request. So thus far the work is only in my local machine's doc directory.

Thanks for the comments.
