How can I use assertions to prevent ValueError in my code?

How can I use assertions to prevent ValueError in my code?

You can use assertions to check conditions that must be true before executing a piece of code. If the condition is false, it raises an AssertionError.

Can you give me an example of how to implement this?

Sure! For instance, if you're expecting a variable to be a positive integer, you can use: assert x > 0, 'x must be positive'.

What happens if the assertion fails?

If the assertion fails, it raises an AssertionError and stops the execution of the program, helping you catch issues early.

Are assertions a good practice in production code?

Assertions are mainly for debugging and should not be used for handling runtime errors in production. Use them to catch programming errors.
