If he did, then he must have changed his mind, because there is nothing ugly about the ternary operator we ended up with. > Guido has alwasys been > against a ternary operator but the requests kept coming.

The fact is that Guido changed his mind about ternary if after discovering that the work-around true-clause and condition or false-clause is buggy -- it gives the wrong answer if true-clause happens to be a false value like [], 0 or None. If I recall correctly, the bug bit Guido himself. The and-or hack, which was *very* common in Python code for many years and many versions, follows the same pattern as ternary if: true-clause if condition else false-clause It astounds me how the Python community changed it's collective mind from admiration of the elegance and simplicity of the expression when it was a buggy hack, to despising it when it became a bug-free language feature. Go figure. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
