Hello,
Is there a way to create a C-style pointer in (pure) Python so the

For example:
a = 1.0
b = 2.0
x = {a:a, b:b}

{'a': 1.0, 'b': 2.0}

1.0 to 100.0 is reflected in the dictionary. I would like to use
simple datatypes such as floats, rather than numpy arrays or classes.

No, Python doesn't do pointers. Rather, objects have references and
that's how the

You can get the same effect with a float by putting it in a container
