Difference between Syntax Error and Exceptions Syntax Error: As the name suggests this error is caused by the wrong syntax in the code.Exception handling syntax is the set of keywords and/or structures provided by a computer programming language to allow exception handling, which separates the handling of errors that arise during a program's operation from its ordinary processes.Handling an exception. If you have some suspicious code that may raise an exception, you can defend your program by placing the suspicious code in a try: block. After the try: block, include an except: statement, followed by a block of code which handles the problem as elegantly as possible. It will be skipped by the C++ compiler. Use the try statement to catch an exception. The { marks the beginning of the body of try/catch block. The code added within the body will become the protected code.

Exceptions get triggered automatically on finding errors in Python. These exceptions are processed using five statements. These are: try/except: catch the error and recover from exceptions hoist by programmers or Python itself.Exception handling uses the try, catch, and finally keywords to try actions that may not succeed, to handle failures when you decide that it's reasonable to do so, and to clean up resources afterward.
