Python exceptions exercises are where robust programming becomes second nature. You’ve seen the theory and built four complete programs. Now it’s time to solve challenges on your own — a password validator, a unit converter and a contact book with custom exceptions. As always: try to solve it yourself, use the hint if stuck for…
In the previous article we covered Python exceptions theory. Now it’s time to write real programs that handle errors gracefully. In this article we build four programs from scratch — a data validator, a robust calculator, a file reader and a class with custom exceptions. Each one uses exceptions in a situation where they’re the…
Python exceptions are the mechanism that lets a program handle unexpected situations without crashing. In FP1 you learned to prevent errors with if/else. In FP2 you go a step further — catching them when they happen and raising them yourself when needed. This article covers everything: try/except, specific and generic exceptions, finally, raise and assert….
