Tim Peters ea76c98014 Implemented <, <=, >, >= for sets, giving subset and proper-subset 
meanings.  I did not add new, e.g., ispropersubset() methods; we're
going nuts on those, and, e.g., there was no "friendly name" for
== either.

Tim Peters 93d8d48c15 TestSubset(): Generalized the framework to support testing upcoming 
<, <=, etc methods too.

Tim Peters 62c62438ff Simplified construction of the test suite. 2002-08-25 17:49:04 +00:00
Tim Peters de830ca4eb Simplified code building sets of characters. 2002-08-25 17:40:29 +00:00
Tim Peters a777799040 Ack! Virtually every test here relied on an assert stmt. assert stmts 
should never be used in tests.  Repaired dozens, but more is needed.

Tim Peters 0bbb30830c Simplified the setup for is-subset testing. 2002-08-25 17:22:23 +00:00
Raymond Hettinger e87ab3fefe Removed < <= > >= from the API. Implemented as comparisons of the 
underlying dictionaries, there were no reasonable use cases (lexicographic
sorting of a list of sets is somewhat esoteric).  Frees the operators
for other uses (such as strict subset and superset comparisons).

Updated documentation and test suite accordingly.

Raymond Hettinger 1b9f5d4c1a At Tim Peter's suggestion, propagated GvR's binary operator changes to 
the inplace operators.  The strategy is to have the operator overloading
code do the work and then to define equivalent method calls which rely on
the operators.  The changes facilitate proper application of TypeError
and NonImplementedErrors.

Added corresponding tests to the test suite to make sure both the operator
and method call versions get exercised.

Add missing tests for difference_update().
