To find out if 'p' is in X Python has to step through the data in X. I'm not sure that your getitem is being called, it may just be a string search operation. But I suspect it may assume the data is an iterator and repeatedly call next() till it gets a match or runs out of data. In that case getitem may well get called. a simple print statement in getitem will find out...
