Debugging that bugger : Cleanly handling the errors
summary
Explains how to read Python tracebacks, use try/except to catch specific errors, and when to raise your own exceptions; demonstrates why a bare except or catching Exception hides real bugs with concrete code samples. Shows using assert as a development-only sanity check that should fail fast and can be disabled, and demos the CLI debugger via pdb.set_trace() with stepping commands (n, s, p) so breakpoints and interactive inspection actually locate the failing line.
