Web Scraping - 股票价格，quandl

Question

我有一个简短的问题。我的代码如下所示：

import quandl

names_of_company = ['KGHM','INDYKPOL','KRUK','KRUSZWICA']

for names in names_of_company:
    x = quandl.get('WSE/{names_of_company}', start_date='2018-11-26', 
    end_date='2018-11-29')

我试图在一个输出中获取所有数据，但我无法一个接一个地更改每家公司的名称。你有什么想法吗？

感谢帮助

Answer 1

除非我遗漏了什么，看起来你应该能够做一个非常基本的 for 循环。是语法不正确。

import quandl
import pandas as pd

names_of_company = ['KGHM','INDYKPOL','KRUK','KRUSZWICA']

results = pd.DataFrame()

for names in names_of_company:
    x = quandl.get('WSE/%s' %names, start_date='2018-11-26', 
    end_date='2018-11-29')
    x['company'] = names
    results = results.append(x).reset_index(drop=True)
