[Image-SIG] assigning commands to a variable

is it possible to assign a string to a variable and then make python 
understand that it is not just text but a command?

The actual problem is that I want to use the PIL filters, which are called


filter_type can be a number of different filter types, like for example 
My user chooses the filter type and then I have to put it in the function

a = "BLUR"
and then


but of course that does not work, as "a" is not recognized as a ImageFilter 
module and also assigning

a = "ImageFilter.BLUR"

does not work.  Is there a trick? (I am obviously not an ace as programmer)

Thank you,
Francesco Pirotti
