This document provides information about exception handling in Python. It begins with a disclaimer and introduction to the mentoring organization. It then defines that exceptions are events that modify program flow or control, such as errors, and can be caught using try/except blocks to handle errors gracefully or try/finally to perform cleanup. Code that may cause exceptions can be placed in a try block, followed by except blocks to handle specific exception types. The document provides an example syntax and contact information at the end.

5. EXCEPTION
 Exceptions are events that can modify the
flow or control through a program.
 They are automatically triggered on errors.
 try/except : catch and recover from raised by
you or Python exceptions
 try/finally: perform cleanup actions whether
exceptions occur or not
 raise: trigger an exception manually in your
code

6. • An exception is an event, which occurs during
the execution of a program, that disrupts the
normal flow of the program's instructions.
• In general, when a Python script encounters a
situation that it can't cope with, it raises an
exception.

7. • 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.

8. syntax
• try:
You do your operations here;
......................
except ExceptionI:
If there is ExceptionI, then execute this block.
except ExceptionII:
If there is ExceptionII, then execute this block.
......................
else:
If there is no exception then execute this block.
