遍历节点列表的问题可以通过以下几种方式解决，下面给出了几种常见的方法及其代码示例：

1. 使用循环遍历节点列表：

class ListNode:
    def __init__(self, val=0, next=None):
        self.val = val
        self.next = next

def traverse_list(head):
    current = head
    while current:
        print(current.val)
        current = current.next

# 创建一个节点列表
node1 = ListNode(1)
node2 = ListNode(2)
node3 = ListNode(3)
node1.next = node2
node2.next = node3

# 遍历节点列表
traverse_list(node1)

2. 使用递归遍历节点列表：

class ListNode:
    def __init__(self, val=0, next=None):
        self.val = val
        self.next = next

def traverse_list(head):
    if head:
        print(head.val)
        traverse_list(head.next)

# 创建一个节点列表
node1 = ListNode(1)
node2 = ListNode(2)
node3 = ListNode(3)
node1.next = node2
node2.next = node3

# 遍历节点列表
traverse_list(node1)

3. 使用生成器遍历节点列表：

class ListNode:
    def __init__(self, val=0, next=None):
        self.val = val
        self.next = next

def traverse_list(head):
    current = head
    while current:
        yield current.val
        current = current.next

# 创建一个节点列表
node1 = ListNode(1)
node2 = ListNode(2)
node3 = ListNode(3)
node1.next = node2
node2.next = node3

# 遍历节点列表
for val in traverse_list(node1):
    print(val)
