An Error can't be recovered as it is fatal in nature, that is different in the case of an Exception that may not be fatal in all cases. A C++ exception is a response to an exceptional circumstance that arises while a program is running, such as an attempt to divide by zero. In contrast, you can throw exceptions of any class type containing any information that you want.

Clarification: Exceptions are those which are encountered during run-time of the program. Moreover, it is not mandatory to have a finally block. Errors are also unchecked exception. However, it is possible to handle an exception in a program using keywords such as try, catch, finally. Error: This is the syntax problem, which leads to complation problem. The catch block simply throws that exception using only throw keyword (not throw e). In programming language errors can be divided into three categories as given below- 1. An error can never be recovered whereas, an exception can be recovered by preparing the code to handle the exception. C++ side needs to catch an exception of type error_already_set and use the native Python API, but you can deduct only the type and not the exception text but is in fact history exception traceback. In a broader way, these errors can be broken into two categories: Design-time errors and Logical errors.
