python使用tkinter实现商品信息的增删改查

好的，下面是一个基于tkinter的商品信息增删改查的示例代码：

from tkinter import *
import tkinter.messagebox as messagebox

class Goods:
    def __init__(self, name, price, stock):
        self.name = name
        self.price = price
        self.stock = stock

class GoodsManagement:
    def __init__(self, master):
        self.master = master
        self.master.title("商品信息管理系统")
        self.master.geometry("500x300")

        # 商品名称
        self.label_name = Label(self.master, text="商品名称：")
        self.label_name.grid(row=0, column=0)
        self.entry_name = Entry(self.master)
        self.entry_name.grid(row=0, column=1)

        # 商品价格
        self.label_price = Label(self.master, text="商品价格：")
        self.label_price.grid(row=1, column=0)
        self.entry_price = Entry(self.master)
        self.entry_price.grid(row=1, column=1)

        # 商品库存
        self.label_stock = Label(self.master, text="商品库存：")
        self.label_stock.grid(row=2, column=0)
        self.entry_stock = Entry(self.master)
        self.entry_stock.grid(row=2, column=1)

        # 操作按钮
        self.btn_add = Button(self.master, text="添加商品", command=self.add_goods)
        self.btn_add.grid(row=3, column=0)
        self.btn_modify = Button(self.master, text="修改商品", command=self.modify_goods)
        self.btn_modify.grid(row=3, column=1)
        self.btn_delete = Button(self.master, text="删除商品", command=self.delete_goods)
        self.btn_delete.grid(row=3, column=2)
        self.btn_search = Button(self.master, text="查询商品", command=self.search_goods)
        self.btn_search.grid(row=3, column=3)

        # 商品列表
        self.goods_list = Listbox(self.master)
        self.goods_list.grid(row=4, columnspan=4, padx=5, pady=5)

        # 初始化商品数据
        self.goods_data = [
            Goods("商品1", 10, 100),
            Goods("商品2", 20, 200),
            Goods("商品3", 30, 300)
        ]
        for goods in self.goods_data:
            self.goods_list.insert(END, goods.name)

    # 添加商品
    def add_goods(self):
        name = self.entry_name.get().strip()
        price = self.entry_price.get().strip()
        stock = self.entry_stock.get().strip()

        if name and price and stock:
            new_goods = Goods(name, int(price), int(stock))
            self.goods_data.append(new_goods)
            self.goods_list.insert(END, new_goods.name)
            messagebox.showinfo("提示", "添加商品成功")
        else:
            messagebox.showwarning("警告", "请填写完整商品信息")

    # 修改商品
    def modify_goods(self):
        index = self.goods_list.curselection()
        if index:
            selected_goods = self.goods_data[index[0]]
            name = self.entry_name.get().strip()
            price = self.entry_price.get().strip()
            stock = self.entry_stock.get().strip()

            if name and price and stock:
                selected_goods.name = name
                selected_goods.price = int(price)
                selected_goods.stock = int(stock)
                self.goods_list.delete(index)
                self.goods_list.insert(index, selected_goods.name)
                messagebox.showinfo("提示", "修改商品成功")
            else:
                messagebox.showwarning("警告", "请填写完整商品信息")
        else:
            messagebox.showwarning("警告", "请选择要修改的商品")

    # 删除商品
    def delete_goods(self):
        index = self.goods_list.curselection()
        if index:
            selected_goods = self.goods_data[index[0]]
            self.goods_data.remove(selected_goods)
            self.goods_list.delete(index)
            self.entry_name.delete(0, END)
            self.entry_price.delete(0, END)
            self.entry_stock.delete(0, END)
            messagebox.showinfo("提示", "删除商品成功")
        else:
            messagebox.showwarning("警告", "请选择要删除的商品")

    # 查询商品
    def search_goods(self):
        name = self.entry_name.get().strip()
        if name:
            self.goods_list.selection_clear(0, END)
            for i, goods in enumerate(self.goods_data):
                if goods.name == name:
                    self.goods_list.selection_set(i)
                    self.entry_name.delete(0, END)
                    self.entry_price.delete(0, END)
                    self.entry_stock.delete(0, END)
                    self.entry_name.insert(END, goods.name)
                    self.entry_price.insert(END, goods.price)
                    self.entry_stock.insert(END, goods.stock)
                    messagebox.showinfo("提示", "查询商品成功")
                    return
            messagebox.showwarning("警告", "未找到该商品")
        else:
            messagebox.showwarning("警告", "请输入要查询的商品名称")


if __name__ == '__main__':
    root = Tk()
    app = GoodsManagement(root)
    root.mainloop()

该示例代码中，我们使用了一个自定义的Goods类表示商品信息，使用一个Listbox控件展示商品列表。在初始化时，我们添加了一些示例商品数据。当用户点击添加、修改、删除、查询按钮时，会调用对应的方法，并在方法中实现相应的操作。当用户选择某个商品时，我们会把该商品的信息显示在输入框中。需要注意的是，这里的添加、修改、删除、查询商品的代码需要根据具体的业务需求进行实现。
