python installation path

I've tried making a package for my python project, and this has an sh script that does some post install python setup.py install for some dependencies/subprojects. But turns out that MacOS installer creates it's own context and screws up some paths so going simply:

  python setup.py install - won't work

One solution that seems to help is to do:

  usr/local/bin/python setup.py install

Now I'm kind of a newbie to MacOS so here are my questions:

1. Is this the default/standard location of python? What I mean is that I plan to distribute this package so can I expect that a machine that has python installed开发者_开发问答 will have a usr/local/bin/python ?
2. In case that the answer to 1. is no, how could I get the location to their python installation? $PATH contains a lot more and $PYTHONPATH is not what I'm looking for either.

You most certainly can not assume that python is installed there. If python is properly installed, it should be in the $PATH, otherewise you just can't know. I could have installed it at /whatever/snake-program/, if it wasn't in the path, how could you guess?

EDIT: What do you mean $PATH contains a lot more by the way? As long as there aren't more than one python install, that shouldn't matter.
