RE: Which is faster? (if not b in m) or (if m.count(b) > 0)

Two additional things beyond the important lesson to always time things: 1. Be careful with operator precedence. In this case, people got lucky: not b in m has the precedence: not (b in m) 2. Python has a "not in" operator: b not in m which is the clearest and fastest way to test
