Can't get rid of TypeError: 'str' object is not callable

Question

我正在尝试 make/train ipython notebook 中的 Twitter 情绪分析器，但有一段代码存在严重问题：

import csv

#Read the tweets one by one and process it
inpTweets = csv.reader(open('SampleTweets.csv', 'rb'), delimiter=',',    quotechar='|')
tweets = []
 for row in inpTweets:
    sentiment = row[0]
    tweet = row[1]
    processedTweet = processTweet(tweet)
    featureVector = getFeatureVector(processedTweet, stopwords)
    tweets.append((featureVector, sentiment));
#end loop

我收到这个错误：

TypeError                                 Traceback (most recent call last)
<ipython-input-10-bbcb1b9f05f4> in <module>()
      7     sentiment = row[0]
      8     tweet = row[1]
----> 9     processedTweet = processTweet(tweet)
     10     featureVector = getFeatureVector(processedTweet, stopwords)
     11     tweets.append((featureVector, sentiment));

TypeError: 'str' object is not callable

帮助会非常好，谢谢！

Answer 1

这里你的 processedTweet 应该是 str 因此你不能调用它。

示例 -

>>> a = 'apple'
>>> a(0)

Traceback (most recent call last):
  File "<pyshell#212>", line 1, in <module>
    a(0)
TypeError: 'str' object is not callable

但是当我使用索引时，没问题。可调用意味着您将其用作求和等函数。

>>> a[0]
'a'
