I do not think that the Python support in this regard is as sophisticated as in the Java world. Have a look at "distribute/setuptools". It supports (a) and (b) (event though you must write a "setup.py" without the help of an UI) and allows to state the dependencies (part of (c)). It can generate a so called "egg" (a distribution unit) representing one distributable component. On installation, you still need a local Python (with its runtime environment) and the installation process will try to resolve the stated dependencies - potentially requiring internet access. In order to get one executable containing the Python interpreter and all required packages, there is "freeze" (and when I remember right a solution provided by "eGenix"). However, you must manually prepare the application such that "freeze" learns about the "required packages". "freeze" is likely too old that it already would interprete the dependency declarations. You might also have a look at "zc.buildout". Its primary task is to ensure the setup of a consistent development/deployment environment across different environments (hosts). It relies on a local Python installation - but can handle almost everything else. Again - without UI support. -- https://mail.python.org/mailman/listinfo/python-list
