sorry about that. I'm new to google groups. I'm trying to make sense of python's implementation of timsort through cpython: http://hg.python.org/cpython/file/default/Objects/listobject.c I was replying to Terry Jan Reedy > > http://hg.python.org/cpython/file/default/Objects/listsort.txt > > is pretty clear (to me) for most of the basics. > Though, if anyone would be interested in helping me out further -- though by all means, I'm not lazy, I can figure it myself. But, I wanted to pass in variables into listsort and watch timsort work line by line in gdb. > > listsort(PyListObject *self, PyObject *args, PyObject *kwds) > > I've never worked with Cpython source before, but it looks like PyObject is just some type of general strut.. I think anyway. How does python represent a list of ints in source? and what are the two second arguments for, assuming the first is the list strut. > On Sunday, June 16, 2013 6:08:50 AM UTC-7, mm0fmf wrote: > Answer: The lost context. > > > > Question: What makes top-posted replies harder to read than bottom-posted? > > > > > > > > alphonse23@gmail.com wrote: > > > Yes I've read it. Very interesting read. There are other resources too online that make it very clear, for instance the wikipedia articles is pretty good. > > > > > > Though, if anyone would be interested in helping me out further -- though by all means, I'm not lazy, I can figure it myself.
