Hi all, I'm in the process of learning Python by writing a job queue program. Nothing fancy, mind you, just read from a table, shell out to a program, write back to the table.
I'm working off of the tutorial listed here (amongst many places): http://www.devx.com/dbzone/Article/22093 In my Jobs class I have: def __iter__(self): "creates a data set, and returns an iterator (self)" q = "select * from %s" % (self.name) self._query(q) return self # an Iterator is an object # with a next() method def next(self): "returns the next item in the data set, or tells Python to stop" r = self.dbc.fetchone() if not r: raise StopIteration return r which works well, but what if I want to modify the __iter__ query? I want to be able to do something like this (and I know this is not the right syntax but you'll get my drift): for job in jobs: print job # which the above code does for job in jobs("status = running"): print job for job in jobs("jobid = 4"): print job What's the pythonic way of doing this? -- Regards, Faber -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. -- http://mail.python.org/mailman/listinfo/python-list
