这是一个关于PYTHON 的PYQT5问题

            self.signal.emit(str(datetime.datetime.now()))




if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    window = Mywindow()
    window.show()


    sys.exit(app.exec_())

上面是我写的窗体连接代码 。 窗体 代码没写,但是 看名字应该可以看出来是什么部件的 对吧 。
有个很奇怪的问题 ,我单步调试的时候,程序就没有问题
如果直接运行程序吗,图片说明

就产生了这个错误,这是为什么呢?

1个回答

datetime.datetime.now()
看看是不是这里,连续运行的时候,产生的时间相等,无法区分
