if __name__ == '__main__': 
    main()

，但我有這個錯誤味精

Traceback (most recent call last): 
    File "C:/Users/Alexandre/Documents/Python/FinalmenteUltimo.py", line 221, in <module> 
    main() 
    File "C:/Users/Alexandre/Documents/Python/FinalmenteUltimo.py", line 215, in main 
    Mw = ClassePrincipal() 
    File "C:/Users/Alexandre/Documents/Python/FinalmenteUltimo.py", line 14, in __init__ 
    self.setupUi(self) 
    File "C:/Users/Alexandre/Documents/Python/FinalmenteUltimo.py", line 17, in setupUi 
    MainWindow.setObjectName 
AttributeError: 'ClassePrincipal' object has no attribute 'setObjectName'

但是，我一直在閱讀有關該模塊，並有這個屬性。

有人可以幫助我，我真的是關於Python的noobo，這是我的firt程序，我不知道發生了什麼。

從現在開始，謝謝。

Ps：我用過QT設計器。

不應該''ClassePrincipal'從一些QT類繼承？ –

是的，在原始代碼中有一些導入語句 –

'__init__'中沒有第二個參數給'setupUi' – erip

由於錯誤消息暗示，第17行有錯誤：我想你錯誤地寫了'MainWindow.setObjectName'兩次，但第一次沒有參數。因此，Python會「思考」你是用這個名稱而不是方法來引用一個屬性，而底層類沒有這樣的屬性（如錯誤中所述）。

對不起，我真正的代碼沒有這條線，我錯誤地發佈，只有完整的行 –

，只是所以你知道，如果我評論這條正確的線，第二個錯誤發生，同樣的錯誤，但現在與調整大小 –

我相信這個文件是由pyuic5生成的。您應該避免手動編輯電腦生成的文件。如果你的.ui文件，你可以嘗試使用下面pyuic5鏈接可能會幫助你

http://pyqt.sourceforge.net/Docs/PyQt5/designer.html

可以讓你的類擴展的QMainWindow和與主窗口更改部分自我象下面這樣setupUi生成PY文件。如果這不起作用使用主窗口選項使用-x標誌在pyuic5上創建你的文件它會給你可執行的Python代碼，這是更好的選擇。同時下面的鏈接應該是有幫助的

self.setObjectName("MainWindow") 
    self.resize(464, 501)

我不編輯，我只是添加主要部分，以相同的方式在這個網頁上發佈。 –

我做到了，解決我只是做了

代替：

class ClassePrincipal(object):

我用

class ClassePrincipal(QMainWindow):

反正謝謝你。
