Python elegant assignment based on True/False values

Question

I have a variable I want to set depending on the values in three booleans. The most straight-forward way is an if statement followed by a series of elifs:

if a a         


        

Answer 1

Here is a truth table approach:

lookup = {'000': 'eighth',
          '001': 'seventh',
          '010': 'sixth',
          '011': 'fifth',
          '100': 'fourth',
          '101': 'third',
          '110': 'second',
          '111': 'first'}

def key(a, b, c):
    return ''.join([str(a),str(b),str(c)])

name = lookup[key(0,1,1)]
