Question

I’m trying to learn the best way to arrange/define code. Taking the below as an example, I have to write the tkMessageBox command twice. I did try to create a def within getText() and refer to that, but it didn’t work.

Questions therefore please

1) How could I arrange the code such that I can place the tkMessageBox command in a def or something and refer to it even within getText()

2) Considering best practice, should this code be layed out differently? If so how/why?

Thank you in advance

import Tkinter as tk
import tkMessageBox
import base64

myText = 'empty'

def getText():
    global myText
    myText = inputBox.get()
    entered = "You entered: " + myText
    encoded = "We encoded: " + base64.encodestring(myText)
    Button1 = tk.Button(root, command = tkMessageBox.showinfo("Press me", entered))
    Button1.pack()
    Button2 = tk.Button(root, command = tkMessageBox.showinfo("Press me", encoded))
    Button2.pack()
    root.destroy()

root = tk.Tk()

# Text label
simpleTitle = tk.Label(root)
simpleTitle['text'] = 'Please enter your input here'
simpleTitle.pack()

# The entry box widget
inputBox = tk.Entry(root)
inputBox.pack()

# The button widget
button = tk.Button(root, text='Submit', command=getText)
button.pack()

tk.mainloop()

I am not sure if you are asking about refactoring your code or not, but the ultimate style guide for laying out/formatting Python code is PEP 8 — Style Guide for Python Code.
