I assume you're basing this on the PEP 8 recommendation: http://www.python.org/dev/peps/pep-0008/#class-names Since there's no difference between a "class" and a "variable containing a class" or a "pointer to a class" or any other such concept, it makes sense to capitalize MyClass in your example, if you are guaranteeing that they're all classes. And certainly a long-lived variable ought to be named in CapWords. However, all you're really doing is taking a bunch of callables, calling them, and making a list of the results. I'd therefore be inclined to _not_ capitalize it. YMMV though. ChrisA
