# This can be a solution: from operator import itemgetter seq1a = ([2] * 4) + ([1] * 4) seq2a = [complex(3-el,7-el) for el in range(1, 9)] assert len(seq1a) == len(seq2a) print seq1a, seq2a, "\n"
mix = zip(seq1a, seq2a) # mix.sort() # Not possible mix.sort(key=itemgetter(0)) # If you need tuples output: seq1b, seq2b = zip(*mix) print seq1b, seq2b, "\n" # Alternative, lists output: seq1b = [el[0] for el in mix] seq2b = [el[1] for el in mix] print seq1b, seq2b, "\n" Bye, bearophile -- http://mail.python.org/mailman/listinfo/python-list
