AttributeError: 'int' object has no attribute 'split' for pandas

Question

AttributeError: 'int' 对象没有属性 'split'

数据是：

print(df)


    Content               Page no
0   My name is mark       3
1   My name is jeff       3
2   My name is bill       3

密码是：

df['doc_len'] = df['Content'].apply(lambda words: len(words.split()))

它返回的错误是：

AttributeError                            Traceback (most recent call last)
<ipython-input-26-7d2f1de16b3d> in <module>
----> 1 df['doc_len'] = df['Content'].apply(lambda words: len(words.split()))

   4139 
   4140         if len(mapped) and isinstance(mapped[0], Series):

AttributeError: 'int' object has no attribute 'split'

Content列是object类型返回int对象没有属性split

Answer 1

你可以试试：

通过 str.split() 和 str.len():

df['doc_len']=df['Content'].str.split().str.len()

或

通过 str.count() 然后添加 1:

df['doc_len']=df['Content'].str.count(' ')+1
