How to separate numbers from an iterable in two lists of even and odd numbers?

Question

The function is supposed to take a list of numbers, and then generate two new lists separating even and uneven numbers in each one.

def separate(list):
    evenList = []
    unevenList = []
    for e in list:
        if e % 2 == 0:
            evenList.append(e)
        elif e % 1 == 0:
            unevenList.append(e)

    print(f"The even list is ", evenList)
    print(f"The uneven list is ", unevenList)        

I notice when my argument ends in an even number, it appends everything into the even list, and same if it ends in an uneven number with the uneven list. I just need a way to iterate based on the conditional, and append only those number that meet the criteria to each new list.

You can do it with two list comprehensions (also, you shouldn't overwrite the builtin python list):

even_lst = [i for i in lst if not i % 2]
odd_lst = [i for i in lst if i % 2]
