an element from a set

[gerardob]

Hello, let S be a python set which is not empty
(http://docs.python.org/library/sets.html)

i would like to obtain one element (anyone, it doesn't matter which one) and
assign it to a variable.

How can i do this?

Thanks.

x = next(iter(s))

or you can supply a default value in case the set is empty:

x = next(iter(s), default_value)
