Finding an item in a set of tuples

I have the following data:

d = set(("John", "Griffin"), ("Lisa","Kane"), ("Mike", "Doyle"), ...)

How do I check this data to see if it contains the first name "Ian" where I have tens of thousands of items in my set?

I guess something like this would work:

len((i for i in d if i[0] == "Ian")) > 0

but is there a more efficient way?

`any(a == 'Ian' for a, b in d)`. – Martijn Pieters Oct 21 '17 at 11:04
Do you have to keep the data that way? A dict would be much more helpful for the particular problem you're asking. – gokhansim Oct 21 '17 at 11:05
