I want to be able to accumulate a string with +=, not by going

think the latter is ugly. There are also times when I'd like to use
the string as a modifiable buffer.

See the StringIO, cStringIO, and array modules.

l=[[None]*5 for i in range(5)]

This is the usual way.

I think this is normally not done.
