title: Why is tuple faster than list in Python?
body: <p>I've just read in <a href="https://www.cmi.ac.in/~madhavan/courses/prog2-2012/docs/diveintopython3/native-datatypes.html#tuples" rel="noreferrer">"Dive into Python"</a> that "tuples are faster than lists".</p>
  
  <p>Tuple is immutable, and list is mutable, but I don't quite understand why tuple is faster.</p>
  
  <p>Anyone did a performance test on this?</p>
