Exception handling 29 Jan 2018

Exception_Handling.py

What is Exception?
An exception is an error that happens during execution of a program. When that
error occurs, Python generate an exception that can be handled, which avoids your
program to crash.
Why use Exception?
Exceptions are convenient in many ways for handling errors and special conditions
in a program. When you think that you have a code which can produce an error then
you can use exception handling
Raising an exception breaks current code execution and returns the exception
back until it is handled.

Some common Exceptions:
  IOError
If the file cannot be opened.

ImportError
If python cannot find the module

ValueError
Raised when a built-in operation or function receives an argument that has the
right type but an inappropriate value

KeyboardInterrupt
Raised when the user hits the interrupt key (normally Control-C or Delete)

EOFError
Raised when one of the built-in functions (input() or raw_input()) hits an
end-of-file condition (EOF) without reading any data
