Generally, if you could multiply strings in the above fashion, you could
spare one more more sub loops, as in this example:
for f in ('index', 'default')*('.html', '.htm', '.shtml'):
In this case, it would be not really be better than that:
for f in 'index', 'default':
for e in '.html', '.htm', '.shtml':
The password cracking was already a better example.
But this would be only efficient if the product of two strings is
returned as a generator, not a list. And I don't know if you really
would expect that, since multiplying a string or a list with a number
does not change its type.
