In some cases, we need to define our own exceptions and throw

Define an error First:

1 class Myerror (baseexception): 2     def __init__ (self): 3         Pass

The above defines a class called Myerror, which inherits from Baseexception. In Python, all errors are inherited from Baseexception, which is equivalent to all exceptions in C # that inherit from exception. Next, an empty constructor is defined.

So how do we throw this exception?

In Python, use the Raise keyword, which is equivalent to throw in C #.

1 Raise Myerror ()

This will allow you to throw an exception.
