In this particular case, you should instead use .belongs(): query = db.product.id.belongs([list of ids])
It's an interesting problem, though. A somewhat hackish solution would be: query = ' OR '.join(str(db.product.id == i) for i in [list of ids]) The problem is that OR and AND operators always wrap the operands in parentheses, even when not necessary. The result is the nesting you observe when using reduce() or appending in a loop. Perhaps there should be a way to suppress the parentheses when not needed.
