Is there a way to create three variables dynamically inside Sum in order

I should have mentioned in my earlier response that 'variable' is a bit
vague and misleading. Python has names bound to objects.
def Sum(D) :
# Here some magic to create a,b,c from D
return a+b+c
No magic is needed.
a, b, c = D['a'], D['b'], D['c']
This is not what most people mean by 'dynamically created variables'.
The names are static, in the code, before the code is executed.
In 2.x, 'from x import *' dynamically creates local names that are not
in the code that contains the import. Dynamically creating objects is
what Python code does all the time.
