Is there a way of using lower more effectively in tkinter

Question

When asking the user for an input I would like it to be set to .lower() like in python when you do start=start.lower() for example. Is there any way I can do this in tkinter without putting Command_Line.get().lower every time due to my code having a code of inputs and me wanting to be efficient?

Answer 1

Here is a simple function and some example code that will modify the value of a string var to lower case. Just pass the stringvar to the function.

from tkinter import *

root = Tk()
#No need for the following line in your code
root.withdraw()


def lowerStringVar(var):
    """Function to convert the text in a StringVar to lower case"""
    if isinstance(var, StringVar):
        var.set(var.get().lower())

myTextVar = StringVar()
myTextVar.set("ALL UPPER CASE")
print(myTextVar.get())

lowerStringVar(myTextVar)

print(myTextVar.get())
