Hello Tutors, I was just wondering if you have a dictionary key is it faster to do: if dict['key'] == 'foo': ... or is this faster: if 'foo' in dict['key']: ... Or is there any difference and I'm chasing ghosts? Thanks, T -- C.T. Matsumoto Claes de Vrieselaan 60a III 3021 JR Rotterdam The Netherlands tel.: +31 (0)6 41 45 08 54
