[issue7915] A lists which list.sort seems to leave out of order.
New submission from Alex Coventry throwa...@mit.edu:
I feel like I must be on crack, here. I apologize if so. English version:
sorting this long list leaves in place element 580395, which is less than
element 0. Restricting to a list of just those two elements, sorting does what
I'd expect.

t = cPickle.load(os.popen('gunzip -c list.pickle.gz')) # Load the pickle
in. It's a list of pairs of numbers
t.sort() # Sort the pickle
t[580395] t[0] # It's not in order!
True
u = [t[0], t[580395]] # Make a list of
just the two compared elements and sort
u.sort()
u == [t[580395], t[0]] # Now it's in order!
True

[issue7915] A lists which list.sort seems to leave out of order.
Alex Coventry throwa...@mit.edu added the comment: No. It's 10M, gzipped. It's constructed from genome-wide association data, which is also huge, intrinsically complex, and protected by rules regarding research on humans. If the bug tracker won't take it do I have any other options? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7915 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
