Changes in Filter in Python3

In python3, after filter processing, it becomes an iterable object. There are 2 solutions:

① Cut into python2

② Put a layer of list outside the filter

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

change to

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
