Bool Flag Handler execute 2 functions on 1st Click, then execute only 2nd function on subsequent clicks

Question

I'm trying to:

open a file and randomly pick values and display them in textbox on 1st click of a button,
then on every subsequent clicks of same button on display new random values — without new prompts for opening file.

My Script:

from tkinter import *
from tkinter import filedialog
from random import sample

root = Tk()
root.title('Name Picker')
root.iconbitmap('c:/myguipython/table.ico')
root.geometry("400x400")

text_file = 0
step1 = text_file
somebool = False

def handler():
    if somebool == False:
        open_txt()
        pick()
    elif somebool == True:
        pick()

def open_txt():
    global text_file
    text_file = filedialog.askopenfilename(initialdir="C:/myguipython/", title="Open Text File", filetypes=(("Text Files", "*.txt"), ))
    name = text_file
    name = name.replace("C:/myguipython/", "")
    name = name.replace(".txt", "")
    
    text_file = open(text_file, 'r')

    somebool = True

def pick():
    global text_file
    step1=text_file.read().strip('"').split('","')
    step2=[]
    for a in step1:
        step2.append(a)
    print(step2)
    
    entries_into_list = step2
    number_of_items = 2

    string_data = [str(data) for data in step2]

    rando = sample(string_data, number_of_items)
    rando1 = sample(string_data, number_of_items)

    my_text.delete(1.0, END)
    my_text.insert(INSERT, " ".join(rando + rando1))

topLabel = Label(root, text="Picked Names", font=("Helvetica", 24))
topLabel.pack(pady=20)
winButton = Button(root, text="pick names", font=("Helvetica", 24), command=handler)
winButton.pack(pady=20)
my_text = Text(root, width=40, height=10, font=("Helvetica", 18))
my_text.pack(pady=10)
root.mainloop()

I used with handler() and command=handler and somebool from those ideas

How to control the events of clicking on a button in tkinter

Using global variables in a function

On 1st he script prompts a 1st time and displays random 1st draws as intended, but on subsequent clicks it still prompts for file opening despite somebool set to True at end of open_txt() function (Handler should not run it again after 1st time, I expect only pick() to run when somebool set to True). Why it is open_txt() still running after somebool set to True? Your help is appreciated.
