I need this a lot: a one line way to do a n-ary and or 'or'.
Here's a one-liner for the n-ary and:
bool(min(bool(x) for x in L))
py> bool(min(bool(x) for x in [1, 1, 1, 0]))
False
py> bool(min(bool(x) for x in [1, 1, 1, 1]))
True
py> bool(min(bool(x) for x in ['a', '', 'b', 'c']))
False
py> bool(min(bool(x) for x in ['a', 'b', 'c', 'd']))
True
Another alternative:
not False in (bool(x) for x in L)
py> not False in (bool(x) for x in [1, 1, 1, 0])
False
py> not False in (bool(x) for x in [1, 1, 1, 1])
True
py> not False in (bool(x) for x in ['a', '', 'b', 'c'])
False
py> not False in (bool(x) for x in ['a', 'b', 'c', 'd'])
True
Note that this should short-circuit, where min won't.
