收银台python tkinter

以下是一个简单的收银台Python tkinter的例子：

import tkinter as tk

class Cashier:
    def __init__(self, master):
        self.master = master
        master.title("收银员1.1")
        master.geometry("400x400")

        # 创建标签和输入框
        self.label1 = tk.Label(master, text="商品名称")
        self.label1.pack()
        self.entry1 = tk.Entry(master)
        self.entry1.pack()

        self.label2 = tk.Label(master, text="商品价格")
        self.label2.pack()
        self.entry2 = tk.Entry(master)
        self.entry2.pack()

        self.label3 = tk.Label(master, text="数量")
        self.label3.pack()
        self.entry3 = tk.Entry(master)
        self.entry3.pack()

        # 创建按钮
        self.button = tk.Button(master, text="计算总价", command=self.calculate)
        self.button.pack()

        self.total_label = tk.Label(master, text="")
        self.total_label.pack()

    def calculate(self):
        # 获取输入框的值
        name = self.entry1.get()
        price = float(self.entry2.get())
        quantity = int(self.entry3.get())

        # 计算总价
        total = price * quantity

        # 显示总价
        self.total_label.config(text=f"{name}的总价为{total}元")

root = tk.Tk()
cashier = Cashier(root)
root.mainloop()

这个例子创建了一个简单的收银台界面，用户可以输入商品名称、价格和数量，然后点击“计算总价”按钮，程序会计算总价并显示在界面上。
