In your Python journey, you’ll come across situations where you need to signal that something is going wrong in your code. For example, maybe a file doesn’t exist, a network or database connection fails, or your code gets invalid input. A common approach to tackle these issues is to raise an exception, notifying the user that an error has occurred. That’s what Python’s raise statement is for. Learning about the raise statement allows you to effectively handle errors and exceptional […]

Or at least, that’s the theory. In practice, your initial Numba code may be no faster than the NumPy equivalent. But you can do better, once you […]
