Quick Answer
Handle exceptions: try/except/else/finally blocks. Catch specific exceptions (except ValueError as e). Custom exceptions: class ValidationError(Exception): pass - inherit from Exception or a more specific base. Add custom attributes in __init__. Re-raise with raise (no args) inside except. Exception chaining: raise NewError() from original_error. Always clean up in finally.
Answer
Use try/except/finally. Create custom exceptions by subclassing Exception. raise MyError("msg"). Ensures clean error handling.
