Graceful Errors: `try-except`
What if the user types text when you expect a number? Your program crashes! Use `try` and `except ValueError` to handle this gracefully.
Focus: Robustness.
Persistent Input: `while` Loop Validation
Sometimes you need input within a specific range (e.g., 1-10). Use a `while True` loop with `if` and `break` to keep asking until the input is valid. Combine this with `try-except` for numbers!
Focus: Validation & Control Flow.
Readable Output: F-Strings
Combining strings and variables with `+` can get messy. F-strings (formatted string literals) offer a clean way! Get multiple inputs and print a neat sentence.
