- 3. EXCEPTION Error caused by not following the proper structure(syntax) of the language is called syntax error. Errors are also occur at runtime and these are called exception They occur, for example, when we try to open file and it not exist (file not FoundError),dividing a number by Zero(Zero DivisionError). When ever these type of run error occour, python creates an exception object.

- 6. Raising Exceptions The raise statement in Python is used to raise an exception. The raise keyword is typically used inside a function or method, and is used to indicate an error condition. We can throw an exception and immediately halt the running of your programme by using the raise keyword.
- 7. Finally Block finally block is always executed after leaving the try statement. In case if some exception was not handled by except block, it is re-raised after execution of finally block. finally block is used to deallocate the system resources.
- 8. User define function Functions that we define ourselves to do certain specific task are referred as user- defined functions. Functions that readily come with Python are called built-in functions.
