作爲OOP的第一個項目,我正在研究一個鏈表oop類,得到了大部分的方法,但remove節點方法不起作用。 當我運行代碼,我得到這個錯誤:如何從鏈表中刪除節點?
AttributeError的:「節點」對象有沒有屬性「VAL」
我想不出我在做什麼錯呢!
class Node():
def __init__(self, val):
self.value = val
self.next = None
class Linked_list():
def __init__(self):
self.next = None
nextnode=self.next
def insert(self, val, loc):
p = self
for i in range(0, loc):
p = p.next
tmp = p.next
newNode = Node(val)
p.next = newNode
newNode.next = tmp
def find(self, val):
p = self.next
# loc = 0 # in case we want to return the location
while p != None:
if p.value == val:
return p
else:
p = p.next
#loc=loc+1 # in case we want to return the location
return None
def remove_node(self, node):
current = self.next
previous = None
found = False
while not found:
if current.val == node:
found = True
else:
previous = current
current = current.next
if previous == None:
self.next = current.next
else:
previous.current.next
def __eq__(self, other):
cnt=0
s=self.next
p=other.next
if Linked_list.length(self)!=Linked_list.length(other):
return False
if s.value==p.value:
for i in range(Linked_list.length(self)-1):
p=p.next
s=s.next
if s.value==p.value:
cnt+=1
if cnt==Linked_list.length(self)-1:
return True
else:
return False
