sorting multiple lists based on a single list in python

Question

I\'m printing a few lists but the values are not sorted.

for f, h, u, ue, b, be, p, pe, m, me in zip(filename, human_rating, rating_unigram, percentage_error         


        

Answer 1

How about this: zip into a list of tuples, sort the list of tuples, then "unzip"?

l = zip(filename, human_rating, ...)
l.sort()
# 'unzip'
filename, human_rating ... = zip(*l)

Or in one line:

filename, human_rating, ... = zip(*sorted(zip(filename, human_rating, ...)))

Sample run:

foo = ["c", "b", "a"]
bar = [1, 2, 3]
foo, bar = zip(*sorted(zip(foo, bar)))
print foo, "|", bar # prints ('a', 'b', 'c') | (3, 2, 1)
