Defining multiple functions in the same def process

[ndc85430]

Is what you really want to do to write a generic function where the thing that varies is a function that's called inside? If so, look into the idea of higher order functions - in Python, functions are values and can be passed around like other things. A higher order function is one that takes another function as a parameter (or returns one, but the former case sounds more useful for you right now). An example of such a thing is the built in map function:

>>> xs = [1, 2, 3]
>>> list(map(lambda x: x * 2, xs))
[2, 4, 6]
>>> words = ["foo", "bar", "baz"]
>>> list(map(lambda w: w.upper(), words))
['FOO', 'BAR', 'BAZ']

map takes a function as its first argument and applies it to each item of the iterable passed as its second argument. In the two examples, I pass in two different functions: one that doubles the argument that I use with the list of ints and one that turns its argument to uppercase, which I use with the list of strings.
