Anatomy of Full Handling
Now let's look at the full structure including `else` and `finally`. Click each part.
Identify all 15 parts!
Predict the Execution Flow
Consider the `else` and `finally` blocks. What sequence of messages will be printed? Choose the correct output.
Refine Generic Handling
Using a broad `except Exception:` can hide bugs. Refine the code below to catch `ValueError` and `TypeError` specifically, each printing a distinct message. Add an `else` block to print "Conversion successful!" if no error occurs.
Build the Handling Structure
Drag the code blocks from the top into the correct zones below (`try`, `except`, `else`, `finally`) to build a logical error handling structure.
Advanced Mini Missions
Combine your skills! Use multiple handlers, `else`, and `finally`.
Mission 1: File Handling Simulation
Simulate opening and reading a file. Use `try`. Catch `FileNotFoundError` (print "File not found.") and `PermissionError` (print "Permission denied."). Use `finally` to always print "File operation finished.".
Mission 2: Robust Division Calc
Get two inputs (numerator, denominator). Convert both to floats. Catch `ValueError` for invalid inputs (print "Invalid number."). Catch `ZeroDivisionError` (print "Cannot divide by zero."). Use `else` to print the division result ONLY if both conversions and the division are successful.
