用python编写超市购物结算器

首先输入你拥有的钱数，然后输入要你买的水果序号和购买的水果的数量，点击结算按钮就可以查看支付的金额数和所剩余的金额

import tkinter as tk
from tkinter import ttk

window=tk.Tk()
window.title("超市")
window.geometry("600x600")

#实例化一个标签
stort1=tk.Label(window,text='水果很贵超市\n-------------------------------------------',font="Arial",bg="red",fg="yellow").pack()


#创建水果列表
f_name=['西瓜','苹果','香蕉','榴莲','橙子','红枣','芒果','哈密瓜']
#创建水果对应列表
f_price_num=[10,20,12,50,13,14,20,9]
#创建序号列表
f_list=[1,2,3,4,5,6,7,8]

#创建表格
columns=("水果名字","水果价格(美元)","序号")
treeview=ttk.Treeview(window,height=10,show="headings",columns=columns)
treeview.heading("水果名字",text="水果名字") #显示表头
treeview.heading("水果价格(美元)",text="水果名价格(美元)")
treeview.heading("序号",text="序号")
treeview.place(x=10,y=80)
#设置宽度
treeview.column("水果名字", width=120, anchor='center')
treeview.column("水果价格(美元)", width=130, anchor='center')
treeview.column("序号", width=130, anchor='center')

#插入函数数据
def test():
    for i in range(min(len(f_name),len(f_price_num),len(f_list))):
        treeview.insert('',i,values=(f_name[i],f_price_num[i],f_list[i]))
Button1=tk.Button(window,text="查看水果",width=20,height=2,fg='pink',bg='black',command=test)
Button1.place(x=150,y=330)




h=tk.Label(window,text="你有多少钱",bg='white')
h.place(x=400,y=200)
h1=tk.Label(window,text="序号",bg='white')
h1.place(x=400,y=170)
h2=tk.Label(window,text="数量",bg='white')
h2.place(x=400,y=220)
h=tk.Entry(window)
h.place(x=500,y=200,width=100)
h1=tk.Entry(window)
h1.place(x=500,y=170,width=100)
h2=tk.Entry(window)
h2.place(x=500,y=220,width=100)

stort2=tk.Label(window,text='购物车\n-------------------------------------------',font="Arial",bg="green",fg="yellow").place(x=100,y=400)


text=tk.Text(window,bg='gray')
text.place(x=10,y=450,width=390,height=300)

def settle_accounts():
    e1 = int(h.get())
    e2 = int(h1.get())
    e3 = int(h2.get())
    total_price=int(e3*f_price_num[e2-1])
    if e1>=total_price:
        text.insert("end","你要购买的水果-------------"+str(f_name[e2-1])+"\n")
        text.insert("end","你需要支付的金额------------"+str(total_price)+"\n")
        text.insert("end","你剩余的金额为--------------"+str(e1-total_price)+"\n")

    else:
        text.insert("end", "钱不够")

butt=tk.Button(window,text="结算",width=18,height=2,bg="black",fg="orange",command=settle_accounts)
butt.place(x=530,y=510)
window.mainloop()

运行结果：
