Actually, you don't need to know operator precedence here because the notation isn't ambiguous in those 2 examples. Of course, it takes some time to understand the thing but it has more to do with the excessive amount of "logic" in one line than with the syntax. -- http://mail.python.org/mailman/listinfo/python-list
