Arrange consonants and vowels nodes in a linked list

class sll(object):
    def __init__(self,val):
        self.value = val
        self.next = None

    def __repr__(self):
        return str(self.value)

def segregate(head,vowels):
    result = sll(0)
    result.next = head
    new_head = result
    mvng_ptr = new_head
    while mvng_ptr.next:
        if mvng_ptr.next.value not in vowels:
            tmp_node = mvng_ptr.next
            mvng_ptr.next = mvng_ptr.next.next
            tmp_node.next = new_head.next
            new_head.next = tmp_node
            new_head = new_head.next
            continue
