这是一个刽子手游戏项目，我正在使用Windows 7机器上的PyQt5和Python。我已经使用相同的设置创建了两个小项目（硬币翻转模拟器和模具辊模拟器）。我还是初学者，这是我的第三个也是最近的＃34;主要＆＃34;项目。我无法得到单词的空白版本与主窗口的中心对齐，似乎无法弄明白。欢迎任何帮助/建议。：）

我认为你遇到的问题是你没有给你的标签明确宽度，因此它只是使用它需要的任何空间。我将标签宽度设置为主要的小部件宽度，然后仅垂直移动，即：

self.blank_word_label = QLabel(blank_word, self)
self.blank_word_label.setFixedWidth(162)
# Or, if you reorder your code so that your self.setGeometry(1427, ...) line occurs before this code, you could do directly:
# self.blank_word_label.setFixedWidth(self.width())
self.blank_word_label.move(0, 200)
self.blank_word_label.setAlignment(Qt.AlignCenter)

或者，我认为你可以让标签自动调整，然后根据宽度和父宽度调整左边。无论如何，要使它居中，你应该始终确保 label.width() + 2 * label.left() == form.width()。即使label.left（）为负数/ label.width（）由于某种原因高于form.width（），这也应该有效。

如何在PyQt5中居中对齐QLabel？
