キャンバスにグリッドを描画して、データの入力を促す方法は？

Question

統計機能が必要なので、私はアナコンダの使い方を学んでいます。しかし、tkinterを使ってキャンバス上で作業とデータ入力をすべて行いたいと思います。結局、正規分布を引きます。私はキャンバス上にグリッドを描画し、4つのセルにデータを入力してキャンバス上ですべてのデータを処理するようにユーザーに促す方法を確信しています。私はこれが最終的にスタンドアローンのプログラムになることを望みます。

import tkinter as tk 
import numpy 
import math 

def fishers(): 
    cell_a = input("Enter Cell A value: ") 
    cell_b = input("Enter Cell B value: ") 
    cell_c = input("Enter Cell C value: ") 
    cell_d = input("Enter Cell D value: ") 
cell_a = float(cell_a) 
cell_b = float(cell_b) 
cell_c = float(cell_c) 
cell_d = float(cell_d) 
fenum = math.factorial(cell_a+cell_b)*math.factorial(cell_c+cell_d)* 
math.factorial(cell_a+cell_c)*math.factorial(cell_b+cell_d) 
feden = 
math.factorial(cell_a)*math.factorial(cell_b)*math.factorial(cell_c)* 
math.factorial(cell_d)*math.factorial(cell_a+cell_b+cell_c+cell_d) 
fe = fenum/feden 
print ("Fishers Exact: =\t {:>8.4f}\n".format(fe)) 
#This is test code to see if I can write into the canvas   
self.fishers.canvas.create_text(100,10,fill="darkblue",font="Times 20 
italic bold", text="We will enter the data here.")

    self.master.title("Quick-Statistics Calculator") 
    self.master.geometry("1000x800") 
    self.pack() 

def widgets(self): 
    main_menu = tk.Menu(self.master, tearoff=0) 
    self.master.config(menu=main_menu) 

    # Create File Menu and Drop Down

    file.add_command(label="Save") 
    file.add_separator()

    means.add_command(label="Group t") 
    means.add_command(label="Paired t")

    means.add_separator() 
    means.add_command(label="Mann-Whitney U") 
    means.add_command(label="Wilcoxon rank sum") 
    main_menu.add_cascade(label="Means", menu=means) 

    #Create Chi-square Analysis Menus and Drop Down 
    chi = tk.Menu(main_menu, tearoff=0) 
    chi.add_command(label="Chi-Square 2x2 table") 
    chi.add_command(label="Chi-Square for larger table") 
    chi.add_separator() 
    chi.add_command(label="McNemar's Test") 
    chi.add_command(label="Fisher's Exact", command=fishers) 
    main_menu.add_cascade(label="Tables", menu=chi) 

    #Create Help Menu 
    help = tk.Menu(main_menu, tearoff=0) 
    help.add_command(label="Means Analysis") 
    help.add_command(label="Chi-Square Analysis") 
    main_menu.add_cascade(label="Help",menu=help) 

main = tk.Tk() 
comm_prog = Window(master=main) 
main.mainloop()

あなたは値を取得するEntry()とButton()でウィンドウを作成するためにToplevel()を使用することができます。

ボタンOKをクリックすると、それが何かを計算すると、キャンバスの上にテキストを配置するためにあなたのコードを使用しています。
