How about using a decorator? Here is a rough version:
def checkPrivs(fn):
fnName = fn.func_name
def restricted(*args):
print "about to call function", fnName
if fnName in listOfAllowedFunctions:
return fn(*args)
else:
raise KeyError("you don't have sufficient privileges to do
THAT")
return restricted
listOfAllowedFunctions = ['add','subtract']
@checkPrivs
def add(a,b):
return a+b
@checkPrivs
def subtract(a,b):
return a-b
@checkPrivs
def multiply(a,b):
return a*b
add(1,2)
subtract(4,1)
multiply(3,2)
