iterating quickly through list of tuples

Question

I wonder whether there\'s a quicker and less time consuming way to iterate over a list of tuples, finding the right match. What I do is:

# this is a very lon         


        

Answer 1

The question is dead but still knowing one more way doesn't hurt:

my_list = [ (old1, new1), (old2, new2), (old3, new3), ... (oldN, newN)]

for first,*args in my_list:
    if first == Value:
        PAIR_FOUND = True
        MATCHING_VALUE = args
        break
