本文介绍了'QString'对象不支持项目分配python的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
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
如果在if循环中遇到此错误,有什么解决方法吗? iam是python的新手,不胜感激....
iam getting this error in if loop, is there any solution? iam new to python any help appreciated....
谢谢
推荐答案
您的问题是您不能通过项目分配(a[2] = ' '
)更改QString
;每当尝试对不允许的对象执行操作时,都会得到TypeError
.您必须创建一个新字符串并将其分配给变量.因此,替换行
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]= ' '
带有以下内容
self.updateTime = self.updateTime[:2] + ' ' +self.updateTime[3:]
