我正在尝试在python中创建一个链表，并且想打印出所有内容，但将其打印为内存位置。我们已经学会了如何在课堂上解决此问题，但目前尚处于半学期，没有人问。
我当前得到的例子：
List: <__main__.LinkedList object at 0x02EA0100>
index: 0 data: 1 item: <__main__.Node object at 0x02EA00D0> pointer: <__main__.Node object at 0x02EA0148>
index: 1 data: 6 item: <__main__.Node object at 0x02EA0148> pointer: <__main__.Node object at 0x02EA0190>
index: 2 data: 3 item: <__main__.Node object at 0x02EA0190> pointer: None
这对我不是很有用。
我用来获得该母胶的方法：
def PrintList(self):
item = self.list_start
index = 0
print(f"List: {self}")
while item:
print(
f"\t index: {index}\t data: {item.data}\t item: {item}\t pointer: {item._get_pointer()}"
)
item = item._get_pointer()
index += 1
我肯定在打印行中出现了问题，我无法发现它。
我知道您不应该在此处放置大量代码，但我需要提供上下文
节点类：
class Node:
def __init__(self,data=None,pointer=None):
self.data = data
self.poiner = pointer
def PrintNode(self):
print(f"Node Data: {self.data}\t self: {self}\t pointer: {self.pointer}\n")
def _set_pointer(self,pointer):
self.pointer = pointer
def _get_pointer(self):
return self.pointer
LinkedLis类别：
class LinkedList:
def __init__(self):
self.list_start = None
def PrintList(self):
item = self.list_start
index = 0
print(f"List: {self}")
while item:
print(
f"\t index: {index}\t data: {item.data}\t item: {item}\t pointer: {item._get_pointer()}"
)
item = item._get_pointer()
index += 1
def _isleagl(self,node):
if node is None:
print(f"node' is None")
return False
elif type(node) != Node:
print(f"'node' has worng type: {type(node)}")
return False
else:
return True
def AppendNode(self,node):
if self._isleagl(node):
if self.list_start == None:
self.list_start = node
node._set_pointer(None)
else:
item = self.list_start
while item:
if item == node:
node = copy.deepcopy(node)
elif item._get_pointer() is None:
item._set_pointer(node)
node._set_pointer(None)
break
else:
item = item._get_pointer()
def DeleteNode(self,node):
if self._islegal(node):
if self.list_start == node:
self.list_start = node._get_pointer()
else:
item = self.list_start
while item:
if item._get_pointer() == node:
item._set_pointer(node._get_pointer())
break
item = item._get_pointer()
