In the sense you mean, no it doesn't.

Python 2.3.4 (#1, Jun  8 2004, 17:41:43) 
[GCC 3.3.3 20040217 (Gentoo Linux 3.3.3, propolice-3.3-7)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> a = 'a'
>>> a
'a'
>>> id(a)
1074037376
>>> a += 'b'
>>> a
'ab'
>>> id(a)
1074272448

Note the two different id numbers. 'a' and 'ab' are not the same string.
