Python wxpython 写一个计算器

好的，我可以为您提供一个 Python wxpython 写的计算器的代码示例：

import wx

class Calculator(wx.Frame):
    def __init__(self, parent, title):
        super(Calculator, self).__init__(parent, title=title, size=(300, 250))

        self.InitUI()
        self.Centre()
        self.Show()

    def InitUI(self):
        vbox = wx.BoxSizer(wx.VERTICAL)

        self.display = wx.TextCtrl(self, style=wx.TE_RIGHT)
        vbox.Add(self.display, flag=wx.EXPAND | wx.TOP | wx.BOTTOM, border=4)

        grid = wx.GridSizer(5, 4, 5, 5)

        grid.AddMany([(wx.Button(self, label='7'), 0, wx.EXPAND),
                      (wx.Button(self, label='8'), 0, wx.EXPAND),
                      (wx.Button(self, label='9'), 0, wx.EXPAND),
                      (wx.Button(self, label='/'), 0, wx.EXPAND),
                      (wx.Button(self, label='4'), 0, wx.EXPAND),
                      (wx.Button(self, label='5'), 0, wx.EXPAND),
                      (wx.Button(self, label='6'), 0, wx.EXPAND),
                      (wx.Button(self, label='*'), 0, wx.EXPAND),
                      (wx.Button(self, label='1'), 0, wx.EXPAND),
                      (wx.Button(self, label='2'), 0, wx.EXPAND),
                      (wx.Button(self, label='3'), 0, wx.EXPAND),
                      (wx.Button(self, label='-'), 0, wx.EXPAND),
                      (wx.Button(self, label='0'), 0, wx.EXPAND),
                      (wx.Button(self, label='.'), 0, wx.EXPAND),
                      (wx.Button(self, label='C'), 0, wx.EXPAND),
                      (wx.Button(self, label='+'), 0, wx.EXPAND),
                      (wx.Button(self, label='='), 0, wx.EXPAND)])

        vbox.Add(grid, proportion=1, flag=wx.EXPAND)
        self.SetSizer(vbox)

        for i in range(0, 16):
            self.Bind(wx.EVT_BUTTON, self.OnButtonClick, id=i)

    def OnButtonClick(self, event):
        button = event.GetEventObject()
        label = button.GetLabel()
        prev = self.display.GetValue()

        if label == '=':
            try:
                result = str(eval(prev))
            except:
                result = 'Error'
            self.display.SetValue(result)
        elif label == 'C':
            self.display.SetValue('')
        else:
            self.display.SetValue(prev + label)

if __name__ == '__main__':
    app = wx.App()
    Calculator(None, title='Calculator')
    app.MainLoop()

希望这个代码能够帮到您！
