How to return a new list that contains just odd elements from data using only recursion

I have been asked to:

Write a function odds(data) that takes a list of ints, data, as a parameter and returns a new list that contains just the odd elements from data, i.e. those elements that are not exactly divisible by two. Your code must not use for or while and must not import anything.

This is my current code:

def odds(data):
    """Returns a new list that contains just the odd elements from the data"""
    odd_nums = []
    if len(data) == 1:
        return []
    
    if data[0] % 2 != 0:   
        odd_nums.append(data[0])
    return odds(data[1:])

Test codes:

print(odds(\[0, 1, 12, 13, 14, 9, -11, -20\]))

---\> \[1, 13, 9, -11\]

I am not sure how to recursively keep adding to the odd_nums list.

>Solution :

def odds(data):
    head = [ data[0] ] if data[0]%2==1 else []
    if len(data)>1:
        return head + odds (data[1:])
    else:
        return head
    
print(odds([0, 1, 12, 13, 14, 9, -11, -20]))

You almost had it. Just combine lists. potentially empty lists are fine
