Python，QT和pyQt GUI

我对python和Qt还是很陌生，距我开始学习python仅两周了。我正在做一个个人项目，机器制造处于最后阶段。这是3D绘图仪。目前，我正在手动发送gcode。我一直盯着使用python，Qt和pyQt开发一个简单的GUI。

我可以在文本框中中给出 X 和 Y 位置，然后单击 ADD 显示在坐标上；文本框。我想要的是输入第一个X，Y值，然后单击 ADD ，它应该从文本框中清除当前的X和Y值，以便我可以输入新值。目前，我手动从框中删除旧值以输入新值。另外，输入新值并添加后，它应该显示在坐标； 文本框中，在先前值下方

;remaining blocks if any

G28 X   ;end gcode

以上是我的输出应显示的样子。此代码中的块数将与添加的X，Y坐标对的数目相同。每个块之间的差异仅在于G0 X<x_coord> Y<y_coord>和G0 X<x_coord - x_offset> Y<y_coord - y_offset>

中X和Y值的变化

点击 Generate Gcode （生成Gcode）按钮时，它应该会产生一个与上述代码相似的文件（如果可能，扩展名为.gcode或.txt，在这种情况下，我将其另存为.gcode在记事本中++） ）

因此，应该如何保存通过文本框输入的X和Y坐标。元组是一个不错的选择吗？如何将输入的x和y值添加到元组？

我不是这个问题的正确平台。如果没有，请重定向我。

欢迎提出建议。
