Generating Random Numbers Under some constraints

I happen to have a list y = [y1, y2, ... yn]. I need to generate random numbers ai such that 0<=ai<=c (for some constant c) and sum of all ai*yi = 0. Can anyone help me out on how to code this in python? Even pseudocode/logic works, I am having a conceptual problem here. While the first constraint is easy to satisfy, I cannot get anything for the second constraint.
