In this part of our python tutorials series, you will learn about the error handling in python. Errors can happen anywhere inside your code. There are times that you know where the problem comes from. There are also times that errors in some part of your code happen for an unknown reason at least until it gets solved. You can use try and except to handle these errors and not allow them to interfere the operation of the rest of your code at the time of running. Using the error handling will also let you know if a certain type of error occurs. You can also create your custom error and raise it when a specific event happens.
