Python 2.7 Unicode 字典

我想知道如何在 Python 2.7 中对 Dict 进行编码。当我执行以下操作时:

# coding=ISO-8859-1 
Programmer = {'v': ["1","2x","3","4","5"]} 
Programmer.update({'x': ["1","2x","3","4","5"]}) 
Programmer.update({'y': ["1","2x","3","4","5"]}) 
Programmer.update({'z': ["1","2x","3","4","5"]}) 
Programmer.update({'æ': ["1","2x","3","4","5"]}) 
Programmer.update({'ø': ["1","2x","3","4","5"]}) 
Programmer.update({'å': ["1","2x","3","4","5"]}) 
print Programmer 

我得到:

{'v': ['1', '2x', '3', '4', '5'], '\xe5': ['1', '2x', '3', '4', '5'], '\xf8': ['1', '2x', '3', '4', '5'], '\xe6': ['1', '2x', '3', '4', '5'], 'y': ['1', '2x', '3', '4', '5'], 'x': ['1', '2x', '3', '4', '5'], 'z': ['1', '2x', '3', '4', '5']} 

我想要的是:

{'v': ['1', '2x', '3', '4', '5'], 'å': ['1', '2x', '3', '4', '5'], 'ø': ['1', '2x', '3', '4', '5'], 'æ': ['1', '2x', '3', '4', '5'], 'y': ['1', '2x', '3', '4', '5'], 'x': ['1', '2x', '3', '4', '5'], 'z': ['1', '2x', '3', '4', '5']} 

编辑:

这是我的工作代码:

# -*- coding: cp1252 -*- 
from PyQt4 import QtCore, QtGui 
import locale 
 
global Programmer 
Programmer = {u'v': ["1","2x","3","4","5"]} 
Programmer.update({u'x': ["1","2x","3","4","5"]}) 
Programmer.update({u'y': ["1","2x","3","4","5"]}) 
Programmer.update({u'z': ["1","2x","3","4","5"]}) 
Programmer.update({u'æ': ["1","2x","3","4","5"]}) 
Programmer.update({u'ø': ["1","2x","3","4","5"]}) 
Programmer.update({u'å': ["1","2x","3","4","5"]}) 
 
class Dialog(QtGui.QDialog): 
    NumGridRows = 3 
    NumButtons = 3 
 
    def __init__(self): 
        super(Dialog, self).__init__() 
        styleComboBox = QtGui.QComboBox() 
        styleComboBox.addItem("UI Item01") 
        styleLabel = QtGui.QLabel("&UI Text:") 
        styleLabel.setBuddy(styleComboBox) 
        opgaveComboBox = QtGui.QComboBox() 
        opgaveComboBox.addItem(u"v") 
        opgaveComboBox.addItem(u"x") 
        opgaveComboBox.addItem(u"å") 
 
        opgaveLabel = QtGui.QLabel("&Opgave:") 
        opgaveLabel.setBuddy(opgaveComboBox) 
 
        self.programComboBox = QtGui.QComboBox() 
        self.programComboBox.addItem("UI item02") 
        programLabel = QtGui.QLabel("&Program:") 
        programLabel.setBuddy(self.programComboBox) 
 
 
        opgaveComboBox.activated[str].connect(self.changeOpgave) 
 
        topLayout = QtGui.QHBoxLayout() 
        topLayout.addWidget(styleLabel) 
        topLayout.addWidget(styleComboBox) 
        #topLayout.addStretch(1) 
 
        topLayoutB = QtGui.QHBoxLayout() 
        topLayoutB.addWidget(opgaveLabel) 
        topLayoutB.addWidget(opgaveComboBox) 
        #topLayoutB.addStretch(1) 
 
        topLayoutC = QtGui.QHBoxLayout() 
        topLayoutC.addWidget(programLabel) 
        topLayoutC.addWidget(self.programComboBox) 
 
 
 
        mainLayout = QtGui.QGridLayout() 
        mainLayout.addLayout(topLayout, 0, 0, 1, 2) 
        mainLayout.addLayout(topLayoutB, 1, 0, 1, 2) 
        mainLayout.addLayout(topLayoutC, 2, 0, 1, 2) 
        mainLayout.setRowStretch(1, 1) 
        mainLayout.setRowStretch(2, 1) 
        mainLayout.setColumnStretch(0, 1) 
        mainLayout.setColumnStretch(1, 1) 
        self.setLayout(mainLayout) 
 
 
 
        self.changeStyle('Cleanlooks') 
        self.setWindowTitle("temp test") 
 
    def changeOpgave(self, opgaveName): 
        self.programComboBox.clear() 
        print "begin 01" 
        print Programmer[opgaveName] 
 
        if not opgaveName in Programmer: 
            print "begin 02" 
            self.programComboBox.addItem("Andet") 
        else: 
            print "go" 
            for item in Programmer[opgaveName]: 
                self.programComboBox.addItem(item) 
 
    def changeStyle(self, styleName): 
        QtGui.QApplication.setStyle(QtGui.QStyleFactory.create(styleName)) 
        self.changePalette() 
 
    def changePalette(self): 
        QtGui.QApplication.setPalette(QtGui.QApplication.style().standardPalette()) 
 
if __name__ == '__main__': 
 
    import sys 
 
    app = QtGui.QApplication(sys.argv) 
    dialog = Dialog() 
    dialog.show() 
    sys.exit(dialog.exec_()) 

我明白了

KeyError: PyQt4.QtCore.QString(u'v') 
KeyError: PyQt4.QtCore.QString(u'x') 
KeyError: "PyQt4.QtCore.QString(u'\xe5') 

尝试从“opgave”列表中选择时 (在第 79 行抛出错误)

请您参考如下方法:

组合框回调传递给 PyQt4.QtCore.QString() 对象，而不是 unicode 字符串。另一方面，您的字典应该使用 unicode() 键(这是正确的做法)。

首先将QString()对象转换为unicode值:

def changeOpgave(self, opgaveName): 
    opgaveName = unicode(opgaveName) 

这是有效的，因为 QString() 对象已经保存了 unicode 数据，并为 Python 提供了正确的钩子(Hook)来进行这种转换，而无需使用显式编解码器重新编码数据。

一旦 opgaveName 值是一个 unicode 键，您就可以使用它来将它与您的字典进行比较。

请注意，您可以只定义字典而无需 .update() 调用:

Programmer = { 
    u'v': ["1","2x","3","4","5"], 
    u'x': ["1","2x","3","4","5"], 
    u'y': ["1","2x","3","4","5"], 
    u'z': ["1","2x","3","4","5"], 
    u'æ': ["1","2x","3","4","5"], 
    u'ø': ["1","2x","3","4","5"], 
    u'å': ["1","2x","3","4","5"], 
} 

global 关键字在您使用它的地方没有任何意义；该关键字仅在函数内部有意义，在这里是多余的。
