Python产生的输出控制台写入程序输出流sys.stdout(正常输出)和sys.stderr(错误输出，如异常回溯)。在这种情况下，我们将使用标准输出

newText = QtCore.pyqtSignal(str)
def write(self, text):
self.newText.emit(str(text))
class Window(QtGui.QMainWindow):

self.setGeometry(50, 50, 500, 300)
self.setWindowTitle("PyQT tuts!")
self.setWindowIcon(QtGui.QIcon('pythonlogo.png'))
self.home()
sys.stdout = Stream(newText=self.onUpdateText)
def onUpdateText(self, text):

cursor.movePosition(QtGui.QTextCursor.End)
cursor.insertText(text)
self.process.setTextCursor(cursor)
self.process.ensureCursorVisible()
