Python 2.7 属性错误：使用Pandas的Python 2.7

在Windows命令面板上运行此程序时，我收到一个属性错误。我有使用Tweepy获得的json数据

import json
import pandas as pd
import matplotlib.pyplot as plt
import re

tweets_data_path = 'C:/Users/e2sn7cy/Documents/GitHub/twitter_data.txt'

tweets_data = []

tweets_file = open(tweets_data_path, 'r')

for line in tweets_file:
    try:
        tweet = json.loads(line)
    except:
        continue
    if not all([x in tweet for x in ['text', 'lang', 'place']]):
        continue
    if tweet['place'] and not 'country' in tweet['place']:
        continue
    tweets_data.append(tweet)

#print len(tweets_data)

#DataFrame
tweets = pd.DataFrame()

#adding columns

tweets['text'] = map(lambda tweet:tweet['text'] if tweet['text'] else '', tweets_data)

#tweets['text'] = [tweet['text'] for tweet in tweets_data]

tweets['lang'] = map(lambda tweet:tweet['lang'] if tweet['lang'] else '', tweets_data)

#tweets['lang'] = [tweet['lang'] for tweet in tweets_data]

tweets['country'] = map(lambda tweet: tweet['place']['country'] if tweet['place'] != None else None, tweets_data)

#Adding Charts
tweets_by_lang = tweets['lang'].value_count()

#pd.value_counts(tweets.values.flatten())

fig, ax = plt.subplots()
ax.tick_params(axis='x', labelsize=15)
ax.tick_params(axis='y', labelsize=10)
ax.set_xlabel('Languages', fontsize=15)
ax.set_ylabel('Number of tweets' , fontsize=15)
ax.set_title('Top 5 languages', fontsize=15, fontweight='bold')
tweets_by_lang[:5].plot(ax=ax, kind='bar', color='red')

属性错误：

(venv) c:\Users\e2sn7cy\Documents\GitHub\Twitter-App>python twitter_analytics.py
Traceback (most recent call last):
  File "twitter_analytics.py", line 41, in <module>
    tweets_by_lang = tweets['lang'].value_count()
  File "C:\myPython\venv\lib\site-packages\pandas\core\generic.py", line 2083, in __getattr__
    (type(self).__name__, name))
AttributeError: 'Series' object has no attribute 'value_count'

它不是

value\u count

更改为：

tweets_by_lang = tweets['lang'].value_counts()

tweets_by_lang = tweets['lang'].value_counts()
