prefsort 0.0.1

Sort a sequence, preferring some values

Partially sort a sequence, preferring some values.

from prefsort import prefsorted
import random

seq = list('abcde')
random.shuffle(seq)

seq2 = prefsorted(seq, 'c b')
assert seq2[0] == 'c'
assert seq2[1] == 'b'
assert set(seq2) == set(seq)

Note that this doesn’t sort the majority of the sequence in the way Python’s normal list.sort() or sorted() do. It just pulls the preferred members to the front of the list.
