How to determine the length of lists in a pandas dataframe column（3个答案）
2天前关闭。
最初有此文本df（称为train）

index                     train
0        My favourite food is anything I didn't have to...
1        Now if he does off himself, everyone will thin...
2                           WHY THE FUCK IS BAYLESS ISOING
3                              To make her feel threatened
4                                   Dirty Southern Wankers

我用这个来计算火车组中的单词：

def word_count(df):
word_count = []
for i in df['text']:
    word = i.split()
    word_count.append(len(word))
return word_count

train['word_count'] = word_count(train)

但是我忘了应用预处理了，在文本中应用预处理后，df是这样的

index                             train
0                     [favourit, food, anyth, didnt, cook]
1        [everyon, think, he, laugh, screw, peopl, inst...]
2                                     [fuck, bayless, iso]
3                                   [make, feel, threaten]
4                                [dirti, southern, wanker]

当我尝试使用def word_count(df):时，出现了一个错误：
AttributeError: 'list' object has no attribute 'split'
因为现在我有一个df，里面有列表。我怎么解决这个问题？

你不需要服装功能，而是这样做：

df['word_count'] = df['train'].apply(lambda x: len(x))
print(df)

train  word_count
0             [favourit, food, anyth, didnt, cook]           5
1  [everyon, think, he, laugh, screw, peopl, inst]           7
2                             [fuck, bayless, iso]           3
3                           [make, feel, threaten]           3
4                        [dirti, southern, wanker]           3

如果你已经有了list，使用str.len()：

df['word_count'] = df['train'].str.len()
print(df)

# Output
                                             train  word_count
0             [favourit, food, anyth, didnt, cook]           5
1  [everyon, think, he, laugh, screw, peopl, inst]           7
2                             [fuck, bayless, iso]           3
3                           [make, feel, threaten]           3
4                        [dirti, southern, wanker]           3
