def my_map(function, iterable):

    for element in iterable:
        result = function(element)
        output.append(result)

    return output

# ------
# If you make a separate method:

def numbers_to_tuples(x):

    output = (x, NAMES[x])
    return output

results2 = my_map(numbers_to_tuples, NUMBERS)

print results
print '-' * 10
print results2
