Python3中的 Filter的改變__Python

在python3中，filter處理之後，變成了一個可迭代對象，解決辦法有2中：

① 切成python2

② 在filter外面套一層list

df = df.dropna()lines=df.content.values.tolist()sentences=[]for line in lines:    try:        segs=jieba.lcut(line)        segs = filter(lambda x:len(x)>1, segs)        segs = filter(lambda x:x not in stopwords, segs)        sentences.append(segs)    except Exception,e:        print line        continue

改成

df = df.dropna()lines=df.content.values.tolist()sentences=[]for line in lines:    try:        segs=jieba.lcut(line)        segs = list(filter(lambda x:len(x)>1, segs))        segs = list(filter(lambda x:x not in stopwords, segs))        sentences.append(segs)    except Exception:        print(line)        continue
