Coding a strategy for the Ultimatum Game

Question

I'm coding different strategies for the Ultimatum Game, which is essentially when a sum of cash is to be shared between two people and one person offers the other a percentage and they either accept or reject. In this strategy I'm assuming there is one proposer but multiple responders (so one person is offering people a percentage of money one after the other, kind of like there's a queue of people waiting to receive an offer) and the proposer starts at 50%, if their offer is accepted 3 times in a row then they lower their offer by 5% and continue offering this amount, if their offer is rejected 3 times in a row then they increase their offer percentage by 5% and continue. I've coded this strategy and, in theory, I believe it should work but it won't run, I think I've made it far more complicated than it needs to be and my python is struggling to run the code. If anyone could help simplify my code or show me a ore efficient method it would help a lot. Thanks in advance

V0.1: First version of this optimisation! Made everything a 1 liner replace while x == true with while x, while x == false become while not x, made vars like x,y=1,2 instead of 2 separate statements.
