Icon is a language that share some similarities with Python:

During the execution of a Icon script there are ways to visualize the
memory:

I'd like to know if for Python there is a similar program to
dynamically see the memory in a similar way.
If such tool doesn't exist yet, I'd like to know if it may be diffifult
to create it.
