The Python Debug Build document lists changes compared to a release build: https://docs.python.org/dev/using/configure.html#python-debug-build
Sometimes, I'm confused that "./python" (Python built locally in debug mode) displays warnings, whereas "python" (Fedora package) doesn't. See also the Python Development Mode: https://docs.python.org/dev/library/devmode.html#devmode The documentation starts with: "The Python Development Mode introduces additional runtime checks that are too expensive to be enabled by default."
