    I assumed you had to preserve the integrity of the data in the list, I did this as a joke lol

    def has_cycle(head):
    if head is None: 
        return 0
    
    while(True):
        if head.data == "foo": 
            return 1
        
        if head.next is None:
            return 0
        head.data ="foo"
        head = head.next

    Though replace foo with something cruder...
