I hate "List index out of range"

[perfringo]

I can't understand the logic of the "index out of range" error

What specifically is beyond your understanding? If you count all items in object starting from zero and get 0, 1, 2 then what should happen if you are looking for item 4? To put it another way - if you have deck of 5 cards what should you say (or do) if somebody asks to give 6th card in the deck?

Slices can be out of range without raising error:

>>> s = 'abc'
>>> len(s)
3
>>> s[3]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IndexError: string index out of range
>>> s[3:]
''
>>> s[100:120]
''
>>> l = [1, 2, 3]
>>> l[3:]
[]
