If/elif condition not triggered when it should in recursive function

I am trying to write code to find whether a given number is odd or even using recursion in Python.

When I execute my code, the recursive function descends down to 0 correctly but then doesn't halt, and keeps going with negative values. I expect it to stop when it reaches 0.

How to make sure the function returns after it reaches zero?

My code:

def odeven(n):
    if n%2 == 0:
        print("even no. : ",n)
    elif n%2 != 0:
        print("odd no. : ",n)
    elif (n == 0):
        return 0
        
    return odeven(n-1)

result = odeven(10)

print("result odd ={}".format(result))
