Question

python2的代码怎么改一下用在python3中

def trainquery(self,wordids,urlids,selectedurl):
# generate a hidden node if necessary
self.generatehiddennode(wordids,urlids)
self.setupnetwork(wordids,urlids)
self.feedforward()
targets=[0.0]*len(urlids)
targets[urlids.index(selectedurl)]=1.0
error = self.backPropagate(targets)
self.updatedatabase()

def updatedatabase(self):
# set them to database values
for i in range(len(self.wordids)):
for j in range(len(self.hiddenids)):
self.setstrength(self.wordids[i],self. hiddenids[j],0,self.wi[i][j])
for j in range(len(self.hiddenids)):
for k in range(len(self.urlids)):
self.setstrength(self.hiddenids[j],self.urlids[k],1,self.wo[j][k])
self.conn.commit()

看下python2To3，不过你的代码如果像上面的话，
其实改不了什么的，我发现变化的部分，我们几乎用不到。
