Even when using Python this is easier said then done. One should be very carefull as details lies in tiny details. Wich I discovered to my shame.
Normally I work on a desktop, this box listenst to the name of Ultra 10, so it is a UltraSparc architecture as developed by Sun Microsystems. Sometimes however, like the last few days, I do use a Compaq Armada M700, which is a Intel i386 architecture. So today I started to work again on the U10, looking where I am I run the unit test suite
test_hpstats.py. Normally I'll have one test failing, this then is the feature I was working on. Two tests failed however.
So why did that test I've forgotten about two days ago sudenly fail? After jotting in some
d.values()[-1][-1]. Very fine, but in one case
d.values() looked like
[[10, 11, 12], [0, 1, 2]] and in the second it was
[[0, 1, 2]]. However as it seemed, when I changed from architecture the order in wich
d.values() is sorted in is changed!
Cheeky. One should be very carefull not to run into traps like this. With reflection I say, "Of course, dictionaries are not sorted!" But the error is made so easily!
