Python 3.x 如何将此代码转换为PyQt5？

我有这个代码我想把这个代码从PyQt4转换成PyQt5

这是密码

import sys
from PyQt4 import QtGui, QtCore

class Example(QtGui.QWidget):
 def __init__(self):
    super(Example, self).__init__()
    self.initUI()

 def initUI(self):     
    hbox = QtGui.QHBoxLayout(self)
    left = QtGui.QFrame(self)       
    left.setFrameShape(QtGui.QFrame.StyledPanel)
    right = QtGui.QFrame(self)
    right.setFrameShape(QtGui.QFrame.StyledPanel)
    splitter = QtGui.QSplitter(QtCore.Qt.Horizontal)
    splitter.addWidget(left)
    splitter.addWidget(right)
    splitter.setStretchFactor(1, 1)
    splitter.setSizes([125, 150])
    hbox.addWidget(splitter)
    self.setLayout(hbox)
    QtGui.QApplication.setStyle(QtGui.QStyleFactory.create('Cleanlooks'))
    self.setGeometry(300, 300, 300, 200)
    self.setWindowTitle('QtGui.QSplitter')
    self.show()

def main():
  app = QtGui.QApplication(sys.argv)
  ex = Example()
  sys.exit(app.exec_())

if __name__ == '__main__':
  main()

如何将此代码转换为pyqt5

试试看：

import sys
#from PyQt4 import QtGui, QtCore
from PyQt5 import Qt

class Example(Qt.QWidget):
 def __init__(self):
    super(Example, self).__init__()

    self.initUI()

 def initUI(self):     
    hbox = Qt.QHBoxLayout(self)
    left = Qt.QFrame(self)       
    left.setFrameShape(Qt.QFrame.StyledPanel)
    left.setStyleSheet('background-color:lightblue; color: white; font-weight: bold;')
    labelLeft = Qt.QLabel(" \n left = Qt.QFrame(self)", left)

    right = Qt.QFrame(self)
    right.setFrameShape(Qt.QFrame.StyledPanel)
    labelRight = Qt.QLabel(" \n right = Qt.QFrame(self)", right)

    splitter = Qt.QSplitter(Qt.Qt.Horizontal)
    splitter.addWidget(left)
    splitter.addWidget(right)
    splitter.setStretchFactor(1, 1)
    splitter.setSizes([125, 150])
    hbox.addWidget(splitter)
    self.setLayout(hbox)

    Qt.QApplication.setStyle(Qt.QStyleFactory.create('Cleanlooks'))
    self.setGeometry(300, 300, 300, 200)
    self.setWindowTitle('Qt.QSplitter')
    self.show()

def main():
  app = Qt.QApplication(sys.argv)
  ex = Example()
  sys.exit(app.exec_())

if __name__ == '__main__':
  main()

将

从PyQt4导入QtGui、QtCore

更改为

从PyQt5导入QtWidgets、QtGui、QtCore

和

QtGui.Q..

更改为

QtWidgets.Q..
