Class vs. Dictionary; or, An Example of Space–Time Tradeoff in Python

Conclusions; or, tl;dr

struct-like objects, i.e. ones that are largely the same as a C struct instance, win in the memory department.
- These tests do not try to determine what is best for very large sets of values, however; I direct the reader to http://stackoverflow.com/a/2670191 for an insight into that scenario when using a dictionary.
Dictionaries beat out objects in access times.
According to Wikipedia, the Python dictionary is highly optimised because it is used internally to implement namespaces. [citation needed]
