Python's equivalent of "EQUIVALENCE" concept in Fortran?

Question

I am interested in rewriting an old Fortran code to Python. The code was for solving any general field variable, call it F (velocity, temperature, pressure, etc). But to solve each variable we have to define EQUIVALENCE of that variable to F .

For example, something like this:

EQUIVALENCE (F(1,1,1),TP(1,1)),(FOLD(1,1,1),TPOLD(1,1))

Is there a Python version of the above concept?

Answer 1

To my knowledge, there is no way to manipulate the memory usage in python. You can perhaps simply use a list.

F=[]

and

FOLD=[]

When you do

F=FOLD 

F and FOLD will point to the same data. I would suggest to use numpy and scipy to create solvers and use python concepts to make it efficient instead of trying to mimic fortran concepts. Especially very old ones.
