Refeing to substring in list of strings

[David Fisher]

Referencing a substring works fine for me:

>>> ll = ['1234','asdf','qwer']
>>> for i in range(len(ll)):
    for j in range(len(ll[i]) - 1):
        print ll[i][j:j+2]


12
23
34
as
sd
df
qw
we
er
>>>

If you're trying to assign to the substring, like s[1:2] = 'e',  you can't,
strings are immutable.
