title: Can't locate collections module for python 3
body: <p>I'm new to Python 3 and following a tutorial which uses a package called collections. While there is an import statement(import collections)in the program, and the program works without error I am confused. I can't locate the package, and it is not listed as one of the downloadable packages. Is it part of python 2/3, and if so where would I see it listed?</p>
