self.value = value
这样就行了撒。
PS：以后贴代码记得把缩进对齐。。。
class Node(object):def __init__(self, value):
self.left = None
self.right = None
self.value = value
class MyBST(object):
def __init__(self):
self.empty = True
def add(self, value):
if self.empty:
self.root = Node(value)
self.empty = False
cur = self.root
while (True):
if not cur:
cur = Node(value)
break
if value >cur.value:
if cur.value != None:
cur = cur.right
else:
newNode = Node(value)
cur.right = newNode
break
elif value <cur.value:
if cur.value != None:
cur = cur.left
else:
newNode = Node(value)
cur.left = newNode
break
else:
cur.value = value
break
在while(True)循环里添加一个if条件判断
