Need to generate some functions.

[Steven W. Orr]

Given a list of names

ll = ("n1", "n2", "n3", "n4")

I want to create a pair of functions based off of each name. An example of
what I want to happen would look like this:

def mkn1dict(address):
return {'Address': address, 'Control': SOME_CONST}

def mkn1Classobj(address):
return Classobj( mkn1classobj(address) )

I know how to do this in a preprocessor, but I'd like to do it directly in
python. Can this be done?

TIA

you can use the dictionary returned by the built in function vars, along
the lines of

>>> vars()["foo"] = lambda x: 3*x
>>> foo(2)

6

but polluting your name space with data counts as bad style and will
probably bite you at some point -- you probably are better of putting
closures in a dictionary:
def something():
return {'Address': address, 'Control': "SOME_CONST"}
return something

>>> mk = {}
>>> mk["n1"] = mkdict("n1")
>>> mk["n1"]()

{'Control': 'SOME_CONST', 'Address': 'n1'}
