Ask for Forgiveness or Look Before You Leap?

This article discusses two fundamental programming paradigms: 'Look Before You Leap' (LBYL), which involves preemptive checks before actions, and 'Easier to Ask for Forgiveness than Permission' (EAFP), which relies on exception handling. It uses Python examples, like reading a file, to illustrate the trade-offs in code simplicity, error coverage, and potential performance implications between the two approaches.
