错误 ： 属性错误： 'NoneType'对象没有属性'strip'

Question

在尝试提取一些文本并通过此站点escape characters删除它时，我遇到了一些错误，任何帮助将不胜感激。 该错误也适用于第二个循环，我正在使用strip来删除escape characters。我想将['We prepare the saddle, and the goat presents itself; is it a burden for the lineage of goats?','You have been crowned a king, and yet you make good-luck charms; would you be crowned God?','We lift a saddle and the goat (kin) scowls; it is no burden for a sheep.']附加到list，并将the text in the bracket附加到另一个list

Answer 1

append

没有return语句，因此返回None。改为对插入的值调用strip()。您还应该添加检查返回值是否str

for i in range(0,220):
# first loop
for br in soup.select('p > br:nth-of-type(2)'):
text = br.previous_sibling
if isinstance(text, str):
edu['Translation'].append(text.strip())
# second loop
for br in soup.select('p > br:nth-of-type(3)'):
text = br.previous_sibling
if isinstance(text, str):
edu['Meaning'].append(text.strip())
