You are getting closer. A better analogy is that using a dict is like transporting passengers along an autobahn in an aeroplane or helicopter that never leaves the ground.
It is not a bad idea to transport passengers in an airplane, but then the airplane should not follow an autobahn, but use the shortest way -- at an appropriate altitude. Translated back to Python dicts, this would mean that using a dict for my purposes is a good idea, but that I do not make use of its full capabilities -- in other words, I should rewrite my code -- still using dict but in a better way. Or do you mean that for 10 kilometers of autobahn, an airplane would be overkill?
Maybe I am a bit biased by my PHP background, but { name: regex, ... } looks simpler to me than [ ( name, regex ), ... ], because the former is not a nested structure, while the latter would be a 2D-array in PHP.
Suppose I use the dict and I want to access the regex associatetd with the token named "tokenname" (that is, no iteration, but a single access). I could simple write tokendict["tokenname"]. But with the list of tuples, I can't think of an equally easy way to do that. But then, as a beginner, I might be underestimating Python.
