setattr() won't work because that's only for objects which have
attributes.  you're talking about creating a (global or local)
variable.  i will also recommend you use a dictionary too... it's
flexible and powerful.

but if you *have* to do it, to paraphrase jonathon's example:

>>> myString = 'rotationalSpeed'
>>> exec '%s = 4500' % myString
>>> print rotationalSpeed
4500

it's ugly but works. this example is more useful if you're planning on
dynamically-generated lots of Python code to execute, not just a
single assignment like this.

good luck!
