The setup.py script is really just an arbitrary program that can do anything and can create files in any location it chooses. Mostly setup.py files have a standard behaviour which is to install files in the site-packages folder for your Python installation (unless you provide command line options indicating an alternative location) and to install executables so that they will be available on PATH. So usually if I have a project called project_name then it will create a folder called project_name in the site-packages folder and then fill that folder with Python files and maybe some other data files. Really though it could do anything so if you need to know exactly what it's doing then you'll need to read the setup.py and understand distutils and setuptools. For example in my system the site-packages folder is called /usr/lib/python2.7/dist-packages For some reason Ubuntu calls it dist-packages but in most Python installations it is called site-packages. If I install ipython by running its setup.py then I will have an egg-info file called: /usr/lib/python2.7/dist-packages/ipython-0.12.1.egg-info and also a folder called /usr/lib/python2.7/dist-packages/IPython which contains all of the Python files for ipython. It also installs an executable file called ipython which is found at /usr/bin/ipython The exact details of what files are installed and where they go can vary depending on what operating system and Python version you are using. -- Oscar ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

However, the desire to do such a thing often means that your real problem is that you are using python setup.py to install packages. This can be ok if that is what you want to do, but it may be that in your case what you want to do instead is to make a virtual environment and install your package(s) there. This means you can keep your system, global-wide environment pure, uncluttered with packages, and have a separate virtualenv for each combination of python packages you want to work with together. And you don't have to worry about which things got installed globally at all -- because none of them do.

[Tutor] Regarding installing a python package
Hi, Could any one please help me understand the following: Suppose I install a python package using python setup.py install provided by the developer of a package. I need to track that changes in my file system.. meaning what new directories and files got created? Also, what is the concept of the egg file that gets created? What would be the location of this egg file and how would it be named .egg? Also, the ***.egg-info directory? Thanks in advance. -- Chirag ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
