# Importing parts of Packages

Some programming languages offer the possibility of importing a single function from a library, as in

from x import y

I'm looking to import only one function (GraphCoordinates) from the GraphUtilities package.

The following commands do not work:

<< GraphUtilitiesGraphCoordinates

Needs["GraphUtilities", "GraphCoordinates"]

The former gives an error, while the latter loads the entire GraphUtilities package.

How should I proceed?

-

Block[{$ContextPath}, Needs["GraphUtilities"]] (see this answer for an explanation), and then refer to your function by its long name: GraphUtilitiesGraphCoordinates You can then go further and create an alias in your current context, if you don't want to type the long name: GraphCoordinates = GraphUtilitiesGraphCoordinates Since the loaded package is not on the$ContextPath, this will not lead to shadowing. Note however that such aliases will work most of the time, but not always.
