self.date = QtCore.QDate.currentDate()
self.time = QtCore.QTime.currentTime()
self.updateTime = QtCore.QString(self.time.toString("hh:mm:ss AP"))
if ((self.time.second() % 2) == 0):
self.updateTime[2]= ' '
self.label.setText(self.updateTime)
Error: TypeError: file line 54: 'QString' object does not support item assignment
iam getting this error in if loop, is there any solution? iam new to python any help appreciated....
thank you
回答1:
Your problem is that you cannot change the the QString by item assignment (a[2] = ' '); you get a TypeError whenever you try to do something to an object that isn't allowed. You have to create a new string and assign it to the variable. So, replace the line
self.updateTime[2]= ' '
with the following
self.updateTime = self.updateTime[:2] + ' ' +self.updateTime[3:]
