Hello!
Someone knows if it's possible to make this __iter__ function with just
one 'yield' intead of two?
Is there some simpler way to make this __iter__ iter through all nodes?
Thanks!
class Node:
def __init__(self, data=None):
self.childs=[]
self.data=data
def appendNode(self, n):
node=Node(n)
self.childs.append(node)
return node
def __str__(self):
return '<'+str(self.data)+'>'
def __iter__(self):
yield self #1
for n in self.childs:
for nn in n.__iter__():
yield nn #2
n=Node()
n.appendNode(1).appendNode(2).appendNode(3).appendNode(4)
n.appendNode(11).appendNode(22).appendNode(33).appendNode(44)
for node in n:
print node
