未找到Python類導入屬性

Question

我是新來的python，我試圖創建一個非常簡單的API調用到REST服務。我需要這些數據才能將其導入到僅支持python的另一個應用程序中。我的問題是我創建了一個python類，並試圖將其導入到我的應用程序中。我有幾個錯誤，然後修改我的類文件，包括添加一個名爲parse_json的新函數。當我現在運行我的應用程序時，它說對象沒有屬性parse_json。當我直接在類中運行代碼時，它運行的是從單獨的文件運行並導入該類給我上面的錯誤。運行

當>我的測試文件

# Import required libraries 
from meetupapi import MeetupAPI 

Meetup = MeetupAPI(
    '/2/members', 
    'xxxxxxx', 
    'xxxxxxx' 
) 
mids = Meetup.get_mid('member') 
group = Meetup.get_gid() 
gid = Meetup.parse_json(group, 'id') 

for mid in mids: 
    member = Meetup.profile(mid, gid) 
    profile = Meetup.parse_json(member) 
    print profile

請記住，我從來沒有在Python中寫過類，所以我可能會錯過一些非常簡單的東西。我查看了所有爲我能找到的其他人提供的答案，但似乎沒有任何結果。任何幫助你可以提供將不勝感激。

檢查lib目錄中的meetupapi.pyc（注意「c」）並將其刪除。然後再次嘗試導入模塊。導入時將模塊編譯爲字節碼。如果您修改文件，則應自動完成新編譯，但可能不會。
