An example, including the error message, would be really helpful here. If you're having issues calling Scipy functions form standard Python, the Scipy lists may be a good place to ask as well. - Robert > > On Jul 6, 3:16 pm, Ahmed Fasih <wuzzyv...@gmail.com> wrote: >> If you're calling Scipy functions from a standard Python environment, >> you won't have the pre-processor issues, so I may be misunderstanding >> what your underlying problem is. >> >> Assuming you are in Sage (since this is a Sage mailing list) and >> calling Scipy, other options that achieve the same effect as the raw >> suffix were detailed on the FAQ: cast the types to float() >> explicitly, >> turn off the pre-processor temporarily, redefine RealNumber() and >> Integer() to float() and int(), etc. etc. >> >> If none of these answer your question, please describe what you're >> trying to do and what errors you are getting. >> >> On Jul 6, 3:57 pm, Mikie <thephantom6...@hotmail.com> wrote: >> >> >> >>> Ahmed, >> >>> Looks good, but I am creating a function in python that is called. >>> And 1r, .56r ,etc. does not pass.
