Question: When would you use a try/except block in code?

1. You use `try/except` blocks when you want to run some code, but need a way to execute different code if an exception is raised.
2. You use `try/except` blocks inside of unit tests so that the unit testes will always pass.
3. You use `try/except` blocks so that you can demonstrate to your code reviewers that you tried a new approach, but if the new approach is not what they were looking for, they can leave comments under the `except` keyword.
4. You use `try/except` blocks so that none of your functions or methods return `None`.

Answer: The correct answer of the above question is Option A:You use `try/except` blocks when you want to run some code, but need a way to execute different code if an exception is raised.
