I have a project of around 6000 lines where I used count() 20 times. It has 14 modules, 10 of which I needed an explicit import.
Many of the usages are of the form: for item, n in zip(items, count(N)): dostuff Around half of these are due to using pylab.subplot(x,y.n), which requires values for n>=1. So I want N=1. The enumerate builtin starts from 0. I also write out textual reports that start with n=1. I also have things like for n, component, rotations in zip(count(), sorted(tools.component_files().keys()), all_symbol_rotations) where the enumerate version just looks even more confusing and easy to mess up for n, component, rotations in enumerate(sorted(tools.component_files().keys()), all_symbol_rotations) Some more examples follow. Note that I find it more natural to specify the count last as it's usually less important than the other values. This is different from the order given by enumerate, so I'm more inclined to use count(). mutated_symbols_and_names = zip(mutated_symbols, (("<%s mutation %s>" % (component, m)) for m in count())) edge_weight=dict(zip(Intersection.types, count(1))) for (component, filename), n in zip(components, count()): for (component, filename), component_count in zip(tools.component_files().items(), count()): -- http://mail.python.org/mailman/listinfo/python-list
