'sorted' from python 2.4 or 2.5 makes test on 'utils.histogram' fail #2

Closed GoogleCodeExporter closed 8 years ago

1) What steps will reproduce the problem?

$ python2.4 doctests.py -v utils.py

or

$ python2.5 doctests.py -v utils.py

2) What is the expected output? What do you see instead?

Failed example:
    histogram(vals, 1) 
Expected:
    [(200, 3), (110, 2), (160, 2), (220, 1), (100, 1)]
Got:
    [(200, 3), (160, 2), (110, 2), (100, 1), (220, 1)]

3) What version of the product are you using? On what operating system?

* Code from SVN repository.
* Debian GNU/Linux (Sid, up-to-date).

4) Please provide any additional information below.

It looks like python's sorted in 2.4 or 2.5 doesn't work exactly as the one
supplied (but I can't try that because I haven't got 2.3, and on 2.4 it
doesn't work).

I'm sure this is not a bug, but maybe you're interested in having
successful tests also on python >= 2.4.

Sorry for such a useless report, otherwise. :-)

This is really a bug in the test, not the code.  Both the "Expected" and "Got"
answers are acceptable -- they both give the 3 value first, then the 2 values, 
then
the 1 values.  They differ on how they break ties, which is acceptable.  I 
should
rewrite the test so that it does not depend on breaking ties one way or the 
other.

Changed the test and the code for histogram to return consistent results across
different Python versions.
