sorting on keys in a list of dicts

[J Berends]

Suppose I have a list of dictionaries and each dict has a common keyname 
with a (sortable) value in it.

How can I shuffle their position in the list in such way that they 
become sorted.

Maybe I am doing it wrongly and you would say: why don't you get 
yourself a (slimmed-down) implementation of a database class. But then 
please guide me on the right path without having to install a xxSQL 
server for my multiplatform code.
