[Tutor] Is there a test for hashability?

2011-09-01 Thread Richard D. Moores
The glossary defines "hashable" as: hashable An object is hashable if it has a hash value which never changes during its lifetime (it needs a __hash__() method), and can be compared to other objects (it needs an __eq__() method). Hashable objects which compare equal must have the same hash value.
