Type Hints for pulp variables

[davidggphy]

Let assume I import pulp as import pulp

When using type hints in pulp, should I use pulp.pulp.LpVariable or pulp.LpVariable. When using type(variable) it returns pulp.pulp.LpVariable.

I assume that the same applied to affine expressions and other pulp objects.

Both are valid. I recommend pulp.LpVariable which is what we use in documentation.
