If the colon is given then either or both of the indices can be omitted.
>>> s = 'abcdefghij'
>>> s[3], s[:3], s[3:], s[-3:], s[:]
('d', 'abc', 'defghij', 'hij', 'abcdefghij')
The other nice thing about [) is that you can shuffle the indexes along
and cover the whole array, i.e. the end index last time becomes the
start index this time.
>>> s = 'abcdefghij'
>>> s[0:3], s[3:6], s[6:9], s[9:12]
('abc', 'def', 'ghi', 'j')
[) has become the norm in "new" languages?
