Python中的关键错误，使用Pycharm和Pandas

Question

我是一个Python新手，在解决一个关键错误时遇到了困难。我已经检查了类似的问题，但仍然无法解决我的问题。下面是错误，后面是代码。如果有任何见解，我将不胜感激

Error (in line 61): 

KeyError: "['Major Office Locations', 'Major Office', '# of International Offices', '# of Attorneys', 'Major Departments', '# of U.S offices'] not in index"

代码：

import requests
import json
import pandas as pd
from bs4 import BeautifulSoup

import concurrent.futures
import sys

URL = 'https://www.vault.com/vault/api/Rankings/LoadMoreCompanyRanksJSON'
pg = 0

year = input('Which Year?  ')
filename = input('Filename? ')

    pg += 1
    params = {'rank': rank,
              'year': year,
              'category': 'LBACCompany',

    response = requests.get(URL, params=params)

        break
    print(pg)
    info = info + json.loads(response.content)

with concurrent.futures.ThreadPoolExecutor(max_workers=100) as executor:
    executor.map(run, list(range(len(info))))

df = pd.DataFrame(data=info)
df = df[['Year', 'Title', 'Rank', '# of U.S offices',
         '# of International Offices', 'Major Office', 'Major Office Locations',
         'Major Departments', '# of Attorneys']]
df.to_excel(filename, index=False)
print('DONE!!!!!!!!!!!!!!!!!!')

看起来您正在尝试设置数据帧的标题（如果我猜对的话）。如果是这种情况，您可以在创建数据帧时通过传入columns关键字参数传入名称，如下所示：

df = pd.DataFrame(data=info, columns=['Year', 'Title', 'Rank', '# of U.S offices', '# of International Offices', 'Major Office', 'Major Office Locations', 'Major Departments', '# of Attorneys'])
