try . . except blokiga else blokini ham qo'shish mumkin. Bu blok hech qanday istisno yuz bermaganda ishga tushadi.

Istisnolarni raise operatori yordamida tegishli xatolik/istisno nomini bergan holda chaqirish mumkin.

Misol: (raising.py nomi bilan saqlang)

class ShortInputException(Exception):

'''Foydalanuvchi klass exceptioni.'''

def __init__(self, length, atleast):

Exception.__init__(self)

self.length = length

self.atleast = atleast

try:

text = input("Nimadir kiriting --> ")

if len(text) < 3:

raise ShortInputException(len(text), 3)

# Bu yerda kerakli amallar bajarilishi mumkin.

except EOFError:

print("Nega EOF qildingiz?")

except ShortInputException as ex:

print("ShortInputException: Kiritilgan satr uzunligi -- {0}; minimum {1} kutilgan edi".format(ex.length, ex.atleast))
