Hi folks, over on the pygr list, we were recently discussing a mildly confusing edit I made: assert 'seq1' in self.db, self.db.keys() This was interpreted by someone as being assert 'seq1' in (self.db, self.db.keys()) which is very different from the actual meaning, assert ('seq1' in self.db), self.db.keys() where 'self.db.keys()' serves as the message to be printed out when the assertion fails. Apart from questions of why I was apparently out to confuse people with this edit, the question of ',' precedence came up. Looking at http://docs.python.org/ref/summary.html there's no mention of ',' binding and tuple creation vs the other operators. I'm not really sure how to think of it but it seems like this is something that could be cleared up in the docs with a brief note somewhere. Thoughts? cheers, --titus -- C. Titus Brown, ctb@msu.edu
