10) D:\Python_classes>py test.py
11) Enter First Number: 10
12) Enter Second Number: 0
13) ZeroDivisionError:Can't divide with zero

14)

15) D:\Python_classes>py test.py
16) Enter First Number: 10
17) Enter Second Number: ten
18) Default Except:Plz provide valid input only

• **Note: If try with multiple except blocks available then default except block should be last,otherwise we will get SyntaxError. Eg:

1) try:
2) print(10/0)
3) except:
4) print("Default Except")
5) except ZeroDivisionError:
6) print("ZeroDivisionError")

7)

8) SyntaxError: default 'except:' must be last

Note:

The following are various possible combinations of except blocks

• except ZeroDivisionError:
• except ZeroDivisionError as msg:
• except (ZeroDivisionError,ValueError) :
• except (ZeroDivisionError,ValueError) as msg:
• except : finally block:
• It is not recommended to maintain clean up code(Resource Deallocating Code or Resource Releasing code) inside try block because there is no guarentee for the execution of every statement inside try block always.
• It is not recommended to maintain clean up code inside except block, because if there is no exception then except block won't be executed. Hence we required some place to maintain clean up code which should be executed always irrespective of whether exception raised or not raised and whether exception handled or not handled. Such type of best place is nothing but finally block. Hence the main purpose of finally block is to maintain clean up code. try: Risky Code except: Handling Code finally: Cleanup code The speciality of finally block is it will be executed always whether exception raised or not raised and whether exception handled or not handled. Case-1: If there is no exception

Case-2: If there is an exception raised but handled:

Case-3: If there is an exception raised but not handled:

• ** Note: There is only one situation where finally block won't be executed ie whenever we are using os._exit(0) function. Whenever we are using os._exit(0) function then Python Virtual Machine itself will be shutdown.In this particular case finally won't be executed.

Note:

os._exit(0)

where 0 represents status code and it indicates normal termination

There are multiple status codes are possible.

Control flow in try-except-finally:

try:

stmt-1

stmt-2

stmt-3

except:

stmt-4
