os.walk 没有看到文件夹中的文件

Question

我前段时间在一个涉及解析推文的项目中使用了以下代码。现在，我想提取更多与这些推文相关的特征，并在我之前解析的相同文件上重新运行它；但是，收到意外错误。错误 中提到的文件 1.json 在目录中 （以及其他数百个 json）。我做错了什么？

import os
import json
import pandas as pd
import numpy as np
from collections import defaultdict

elements_keys = ['created_at', 'text', 'lang', 'geo', 'location', 'quote_count', 'reply_count', 'retweet_count', 'favorite_count', 'in_reply_to_screen_name', 'screen_name', 'description', 'verified', 'followers_count', 'friends_count', 'listed_count', 'favourites_count', 'statuses_count']
elements = defaultdict(list)

for dirs, subdirs, files in os.walk('/Users/user/Desktop/'):
    for file in files:
        if file.endswith('.json'):
            with open(file, 'r') as input_file: # print (tweet.keys())
                for line in input_file:
                    try:
                        tweet = json.loads(line)
                        items = [(key, tweet[key]) for key in elements_keys] # should raise error if any key is missing
                        for key, value in items:
                            elements[key].append(value)
                    except:
                        continue

df=pd.DataFrame({'created_at': pd.Index(elements['created_at']),
                 'text': pd.Index(elements['text']),
                 'lang': pd.Index(elements['lang']),
                 'geo': pd.Index(elements['geo']),
                 'location': pd.Index(elements['location']),
                 'quote_count': pd.Index(elements['quote_count']),
                 'reply_count': pd.Index(elements['reply_count']),
                 'retweet_count': pd.Index(elements['retweet_count']),
                 'favorite_count': pd.Index(elements['favorite_count']),
                 'in_reply_to_screen_name': pd.Index(elements['in_reply_to_screen_name']),
                 'screen_name': pd.Index(elements['screen_name']),
                 'verified': pd.Index(elements['verified']),
                 'followers_count': pd.Index(elements['followers_count']),
                 'friends_count': pd.Index(elements['friends_count']),
                 'listed_count': pd.Index(elements['listed_count']),
                 'favourites_count': pd.Index(elements['favourites_count']),
                 'statuses_count': pd.Index(elements['statuses_count'])})

df.to_csv('df.csv')

Answer 1

哦，我想我刚刚弄明白了：

for dirs, subdirs, files in os.walk('/Users/user/Desktop/*.json'):

我已经有一段时间没用了Python。对不起:)

os.walk 没有看到文件夹中的文件

os.walk does not see files that are in the folder

parsing

os.walk
