I'm looking for some free advice. ;)
My dbf module has three basic containers, all of which support list-like
access: Table, List, and Index, each of which is filled with
_DbfRecords.
The fun part is that a _DbfRecord can compare equal to another
_DbfRecord, a _DbfRecordTemplate, a tuple with the same values in the
same locations, or a dict with the same keys/fields and values.
The really fun part is __contains__: should the __contains__ method
return True when a _DbfRecordTemplate, tuple, or dict is looked up in
the Table, List, or Index and there is a matching record?
Well, if x is in c and x == y, then y is in c. Does that help? ;-)
Heh, that's pretty much the conclusion I was coming to. As a more
concrete example:
--> x = 4.0
--> x in [1, 4, 7, 4, 9, 3, 4]
True
It's checking for equality, not identity.
Thinks for helping me think that through.
