我编写了以下代码在 Pycharm 中制作网格。无法进行数学计算

import wx
import wx.grid as grid

class MyFrame(wx.Frame):
    def __init__(self, parent, title):
        super(MyFrame, self).__init__(parent, title=title, size = (600, 800))

        #self.panel = wx.Panel (self)

        self.panel = MyPanel(self)

class MyPanel(wx.Panel) : 
    def __init__(self, parent) :
        super(MyPanel, self). __init__(parent)

        madrid  =   grid.Grid(self)
        madrid.CreateGrid(40, 8)

        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(madrid, 1 , wx.EXPAND)
        self.SetSizer(sizer)

class MyApp(wx.App):
     def OnInit(self):
         self.frame = MyFrame(parent=None, title="Electrical Sizing File")
         self.frame.Show()
         return True

app =   MyApp()
app.MainLoop()
