At an attribute level, absolutely, but not at the variable level like
the OP is requesting.
It's a great package, though :)

Strictly speaking, no, but there may be a way to get something close

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

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

Hello,
Is there a way to create a C-style pointer in (pure) Python so the
following code will reflect the changes to the variable "a" in the
dictionary "x"?
For example:
>>> a = 1.0
>>> b = 2.0
>>> x = {"a":a, "b":b}
>>> x
{'a': 1.0, 'b': 2.0}
>>> a = 100.0
>>> x
{'a': 1.0, 'b': 2.0} ## at
