「數據幀」對象不是可調用的函數

的這樣的代碼，我可以得到一個CSV文件，但我得到了一些錯誤：「數據幀」對象不是可調用的函數

對方的回答也解決不了我的問題。

在url_dict.items（）中爲'name，url的第二次迭代得到這個錯誤：'-loop？ – Rojan

是的，我只收到一個csv文件。 – pang2016

您應該更改返回對象的名稱，例如：'final = final_data（url）' – Chr

在第二次迭代，final_data不被認爲是一個函數。您應該更改返回對象的名稱。

if __name__ == '__main__': 
    for name, url in url_dict.items(): 
     final = final_data(url) 
     if type(final) == str: 
      print name + 'empty' 
     else: 
      final.to_csv(name+'_{}.csv'.format(yesterday),encoding='utf-8') 
      time.sleep(8)
