cookie['lastvisit'] is a string.

Here you're using the string 'expires' as an index into the
string returned by str(time.time()).  You can only index into
strings using integers.

What do you expect the following statement to do?

    '1260910829.18'['expires'] = <whatever>

You took the string returned by str(time.time()) and tried to
use 'expires' as an index into that time string.  You can't use
a string to index into a string.  You can only use integers.
That's what is mean't by the error message:

    TypeError: string indices must be integers
