Something like 

def func(my_func,seq):
    return seq, [my_func(n) for n in seq]

or

def func(my_func,seq):
    return [(my_func(n),n) for n in seq]

... your description is not very clear in that regard.

What's being used here is a list comprehension. my_func is called once for every element in seq and should return the function value for this element.
