我是python的新手,我想做一个购物车,并且我正在使用w python,我从txt中获取数据,并且完成了window和button事件,但是当我追加数据发送到其他面板,这只能累积到一个点

inventario.txt

您的0 */2 * * * /home/username/test.sh 数据不完整或结构不正确。
我假设您收到以下错误消息:

inventario.txt

Traceback (most recent call last): File "window.py", line 22, in onButton p2sz.Add(wx.SpinCtrl(p2,label=combo.GetValue()),0,wx.EXPAND) TypeError: SpinCtrl(): arguments did not match any overloaded call: overload 1: too many arguments overload 2: 'label' is not a valid keyword argument 没有wx.SpinCtrl,但确实有label
将该行更改为:

value

声明

self.p2sz.Add(wx.SpinCtrl(p2,value=str(combo.GetSelection())),0,wx.EXPAND)
在回调self.p2sz = wx.GridSizer(len(productos),3,2,0) p2.SetSizer(self.p2sz) __init__定义中的

不是
之后,所有对p2sz的引用都应为self.p2sz
实际上,您每次单击按钮时都声明onbutton

如果您不熟悉p2sz,则可能需要查看以下说明:https://medium.com/quick-code/understanding-self-in-python-a3704319e5f0

请注意,您对self大小调整器的编码风格非常过时,我鼓励您抛弃所有正在使用的资源,寻找更现代的东西,例如https://wiki.wxpython.org/SizerTutorials
