Python - How To Get The Sum, Max, Min, Avg Value Of A TreeView Column Using Python Tkinter
In This Python Tutorial We Will See How To Get The Average, Max, Min, Sum Value From Specific Treeview Column And Display Them In TextBoxes Using Python Programming Language.
Project Source Code:
import tkinter as tk
from tkinter import *
from tkinter import ttk
root = Tk()
root.title("MAX-MIN-SUM-AVG")
frame_container = tk.Frame(root, padx=10, pady=10, bg='#badc58')
frame_fields = tk.Frame(frame_container, bg='#badc58')
# create treeview
trv = ttk.Treeview(frame_container, columns=(1,2,3,4), show='headings')
trv.column(1, anchor='center', width=100)
trv.column(2, anchor='center', width=100)
trv.column(3, anchor='center', width=100)
trv.column(4, anchor='center', width=100)
trv.heading(1, text='ID')
trv.heading(2, text='Name')
trv.heading(3, text='Quantity')
trv.heading(4, text='Price')
# add items to the treeview
trv.insert("",'end', iid=1, values=(1,"Product 1",100, 10))
