Howdy,

Is it possible to create a python extension function that takes an integer for the first parameter, and then a variable parameter for a second parameter, like I can do with a coffee extension function?

For instance if I want the first parameter to be an ID, and then the second parameter to be either a bool, integer or float. Is that possible?

Adios

Howdy,

OK, never mind. I took an educated guess and it worked perfectly:

LONG id;
GeData gdata;
  
const CHAR *kwlist[] = {"integer", "gedata", NULL};
if(!pylib.ParseTupleAndKeywords(args, keywords, "iG", kwlist, &id, &gdata)) return pylib.ReturnPyFALSE();
  
if(gdata.GetType() != DA_LONG && gdata.GetType() != DA_REAL) return pylib.ReturnPyFALSE();

The last line checks the type, so the function only accepts a bool, int or float (a bool is actually an int). 

Adios,

Hi,

Yes, using a GeData is the way to go in Python to parse a parameter that can be of various types.

Howdy,

Well, the educated guess was mainly in the use of the string "gedata". I sort of knew that a GeData was the way to go.

That's why I asked in the other thread if you could post a complete list of parameters for the different types. 

Adios,
