If you're going to use 'all', why use a set?
return all(f(x) for f, x in zip(c,

Ok, I have understood now, I didn't noticed it was a set and not a list.

What are the restrictions on the constraints them

Hello,
I need to implement a function that returns 1 only if all the values in a list
satisfy given constraints (at least one constraint for each element in the
list), and zero otherwise.
For example, I may have a list L = [1, 2, 3, 4] and the following constraints:
L[0] >= 1
L[1] <= 3
L[2] ==
12 matches
