python - 無法從pyuic4生成的文件中導入名稱

Question

我有以下兩個腳本，其中第一個是使用pyuic4 for Windows生成的，並且未被修改。

textedit.py：

# -*- coding: utf-8 -*-

start.py：

#! /usr/bin/env python3.4 

import sys 
from PyQt4 import QtCore, QtGui 
from textedit import UI_notepad 

class StartQT4(QtGui.QMainWindow): 
    """docstring for StartQT4""" 
    def __init__(self, parent=None): 
     QtGui.QMainWindow.__init__(self, parent) 
     self.parent = parent 
     self.ui = UI_notepad() 
     self.ui.setupUi(self) 

if __name__ == '__main__': 
    app = QtGui.QApplication(sys.argv) 
    myapp = StartQT4() 
    myapp.show() 
    sys.exit(app.exec_()) 

我如何導入作品相當好理解，但無論我嘗試，我總是得到錯誤：

Traceback (most recent call last): 
    File "E:\Python\Text Editor\start.py", line 5, in <module> 
    from textedit import UI_notepad 
ImportError: cannot import name 'UI_notepad' 

Answer 1

您需要小寫i在from textedit import Ui_notepad

您使用from textedit import UI_notepad和你的類是：

class Ui_notepad(object) < - i沒有I
