"Invisible Walls: Isolating Your Python"
summary
A small demo app called A Notch Above works locally but fails elsewhere until the exact interpreter and libraries are fixed: Python defaults to 2.7, a dependency breaks on Python 3.10, and the working combination is Python 3.9 plus an explicit install. Using venv/virtualenv isolates per-project site-packages and fixes pip conflicts, but C extensions like the system SSL library mismatch escape venvs, requiring deeper runtime isolation or reproducible runtimes (containers or ActiveState-style environments).
