""" Define the get_evens_at_back() function which is passed a list of
integers as a parameter. The function returns a new list with all the
odd numbers from the parameter list (in sorted order) at the front and
all the even numbers from the parameter list (in sorted order) at the
back of the list.  If the parameter list is empty, the function should
return an empty list. For example, the following code:

print("1.", get_evens_at_back([-1, 2, -3, 4, -2, 3, 5]))
print("2.", get_evens_at_back([1, 2, -3, 4, 7, 4, -6, 3, -1]))
print("3.", get_evens_at_back([-4, -2, 6, 8, 6, 2]))
print("4.", get_evens_at_back([-3, -1, 3, 1, 7, 9]))
print("5.", get_evens_at_back([]))

prints:

1. [-3, -1, 3, 5, -2, 2, 4]
2. [-3, -1, 1, 3, 7, -6, 2, 4, 4]
