Fortran Routine calling a Python Function

[LucasCampos]

I have been trying to merge some python with fortran, to build a nice interface but still be fast. I spent the last two days learning how to use f2py, buy everything would be so much easier if I could call a Python function from Fortran instead of doing the other way around.

Anyone know how to do something like that, if it's even possible?

For example

Subroutine Example (var1,var2)
Implicit None
Real, Intent(in) :: var1,var2
Real :: var3,var4
command1
command2
.
.
.
pythonfunction(var3,var4)
.
.
.
commandn
EndSubroutine

I found several articles that discussed fortran mixed-languague programming (my search string was 'fortran "mixed language" programming'. One article that showed up showed how to call a C function from fortran (http://www.vni.com/company/whitepapers/StandardizedMixedLanguageProgrammingforCandFortran.pdf , page 10).

It might be more difficult to call a python function from fortran, unless the python code could be compiled, instead of being interpreted, which is the usual case, I believe.

Thanks for the answer, but I've given up all hope to call python from fortran. I remade my fortran program to be used with python. Took me the whole afternoon, far less than I expected, and the result was quite nice.

Python is quite a cool language to use with fortran. I wouldn't even think of doing a GUI on fortran, and on python took me just one afternoon, learning included!
