Is there a function in SageMath that gives the actual size of a variable not of a pointer to the variable? I used "getsizeof" function but the size it showed is very small comparing to the long of the equation is.

edit

Please provide an actual code illustrating the question.

.

# Measure and display the size of each function in P
for i, func in enumerate(P):
    size_in_bytes = sys.getsizeof(func)
    show(f"Size of P[{i}] (function for state {all_states[i]}): {size_in_bytes} bytes")

I am looking for alternative command of "getsizeof" as it is not measuring the actual size of my functions P. it gives all functions have same size 56 bytes which it can't be as there length are different

FWIW, the same thng happens on Python.
