问题[pyqt]

给出此错误名称 'Translate_points' 是参数和全局的。计数器不工作。如何使函数工作的结果可供下一个函数读取？

    import random
     def V1_inputf1(Translate_points):
        print(Translate_1,'рандомный глагол')
        Infinitive_input=input("введите инфинитив ",)
        if Infinitive_input==Infinitive[index_Translate]:
            Translate_points += 1
            return Translate_points
        else:
            Translate_points -= 1
            return Translate_points
    def V2_inputf1(Translate_points):
        print(Translate_1,'рандомный глагол')
        Past_Simple_input=input("Введите вторую форму ",)
        global Translate_points
        if Past_Simple_input==Past_Simple[index_Translate]:
            Translate_points += 1
            return Translate_points
        else:
            Translate_points -= 1
            return Translate_points
     def THE_END():
       print("______________________________________________________________________________")
       print("______________________________________________________________________________")  





while Translate_points<15:
    Translate = ['гнуть', 'строить', 'золотить', 'одалживать', 'отправлять', 'тратить', 'разгибаться']
    Infinitive = ["bend", "build", "gild", "lend", "send", "spend", "unbend"]  # Инфинитив
    Past_Simple = ["bent", "built", "gilt", "lent", "sent", "spent", "unbent"]  # Вторая форма
    Participle_2 = ["bent", "built", "gilt", "lent", "sent", "spent", "unbent"]  # Третья форма
    Translate_1=random.choice(Translate)
    print(Translate_1,'рандомный глагол')
    index_Translate=Translate.index(Translate_1)
    print(Infinitive[index_Translate],'-',Past_Simple[index_Translate],'-',Participle_2[index_Translate])

  print(V1_inputf1(Translate_points))
  print(V2_inputf1(Translate_points))

在我的帮助下，我StyleSheet添加了一张图片作为背景，将窗口的大小调整为这张图片的大小。但是图像的一部分（标记为红色）有一定的边界。

问题 - 如何删除此边框？

鼠标悬停时，背景只在按钮文字后面发生变化，但按钮本身的边框明显变大了。

为什么会发生这种情况，我还没有弄清楚。我想改变按钮的整个背景，就像第二张图片一样（但是，背景必须是纯色的）。

以下是styleSheet按钮：

QPushButton{
    background: rgba(0, 0,0,0);
    margin: 20, 20, 0, 0
}

QPushButton:hover{
    background:rgba(0, 0, 0,30)
}

我不明白如何使它在您单击时item添加一个子item项，否则它会被添加到根目录item中。

# path = os.path.dirname(__file__)
path = os.path.dirname(os.path.dirname(__file__))


class Conv(QDialog):
    def __init__(self):
        super().__init__()
        self.resize(500, 400)

        self.tree = QTreeWidget(self)
        self.tree.header().hide()

        self.btn = QPushButton('Add', self)
        self.btn.move(300, 200)
        self.btn.clicked.connect(self.addy)

        # self.fileTree()
        self.items()

    def items(self):
        item = QTreeWidgetItem()
        item.setText(0, 'Начало')
        self.tree.addTopLevelItem(item)
        q = QTreeWidgetItem(item)
        q.setText(0, 'Hello')



    def addy(self):
        if self.tree.selectedItems():
            b = QTreeWidgetItem(self.tree)
            b.setText(0, 'New')

写了一个程序来计算面积。没有错误，但是当我点击计算区域时，结果没有显示在按钮旁边的标签中。

我做错了什么？
