How to Fix: Better to 'try' something and catch the exception or test if it's possible first to avoid an exception?

When deciding between testing if something is valid or trying to do it and catching the exception, there isn't a clear consensus in Python documentation. However, both approaches have their own advantages.

🔍 Why This Happens

• Testing if something is valid allows you to handle the situation gracefully and avoid exceptions, which can be useful in certain situations.
• Trying to do it and catching the exception can lead to unexpected behavior or errors if not handled properly.

✨ Wrapping Up

In conclusion, both approaches have their own merits. Defensive programming provides a more robust and predictable way of handling invalid inputs, while error handling can be useful in situations where the input is valid but still requires special treatment.
