There are tools in the python ecosystem that know how to build stand alone apps for python. These tools can figure out the minimum set of python and .so/.dylib/.dll that are needed.
I use these tools when building apps for Windows and macOS where I do not require that python is pre-installed. You can use the same technics for unix systems. 1. Start with standard python 2. pip install deps 3. run tool to create minimum app If you build multiple apps then you can share common files to cut down size as well.
