help with assignment

[Mof44]

Here's what I've done so far...

def print_segment(n, total_width):
    for size in range(1, n+1, 2):
        print((size * "X").center(total_width))

def print_spruce(size):
    for i in range(3, size+1, 2):
       print_segment(i, size)

print("Write the size of the spruce:")
n = int(input())
print_spruce(n)
