[Tutor] Sorting more than one list

[py]

An alternative way of doing this (if you have python 2.4):

>>> ppl =   ['john', 'mary', 'lary', 'jane']
>>> age =   [15, 30, 23, 25]
>>> height= [160, 165, 178, 170]

>>> sortby = lambda a, b: [a[b.index(x)] for x in sorted(b)]
>>> sortby(ppl, age)
['john', 'lary', 'jane', 'mary']
>>> sortby(ppl, height)
['john', 'mary', 'jane', 'lary']

>>> age    # age is not changed
[15, 30, 23, 25]
