Mistakes in documentation

[Paul Volkov]

Where can I submit little mistakes in Python documantation?
I found one while browsing tutorial.pdf (Python 3.3.2):

Section 3.1 says (on page 12):

word[2:5] # characters from position 2 (included) to 4 (excluded)

’tho’

Shouldn't the comment say "5 (excluded)" or "4 (included)" instead?
