Get the output label of calender toplevel from the master window having "Select Date" button, tkinter

Question

I have a doubt, how to get the top-level value in the master window's label. I mean like i couldn't return the entered value from toplevel window to main's self. I tried other ways and it didn't work

import tkinter as tk
from tkinter import ttk
from tkinter import filedialog
from tkcalendar import Calendar, DateEntry
  
class Application(tk.Frame):
    
    def _init_(self,master):
        Frame._init_(self,master)
        self.master=master
        self.label=Label(text="",font=("Georgia,12"))
        self.label.place(x=50,y=80)
        self.create_widgets() 
    

def calendar_view():
    def print_sel():
        return cal.get()
        
    top = tk.Toplevel(root)
        
    cal = Calendar(top,
                   font="Arial 14",selectmode='day',
                    cursor="hand1", year=2020)         
    cal.pack(fill="both", expand=True)
    ttk.Button(top, text="ok", command=print_sel).pack()                   
root=tk.Tk()

s = ttk.Style(root)
s.theme_use('clam')
root.title("Date")
root.geometry("800x500")

button = tk.Button(root, text = 'Test Start Date', bg='#0073BD',height=1,width=15,padx=5,pady=2, fg="white",command=calendar_view)
button.place(x=500,y=100)
label1 = tk.Label(root, text="<-Click to select Test Start Date", padx=10, pady=10, bg="#e6e9f2", font=("calibri",8))
label1.place(x=630,y=100)

button = tk.Button(root, text = 'Test End Date', bg='#0073BD',height=1,width=15,padx=5,pady=2,fg="white",command=calendar_view)
button.place(x=500,y=150)
label1 = tk.Label(root, text="<-Click to select Test End Date", padx=10, pady=10, bg="#e6e9f2", font=("calibri",8))
label1.place(x=630,y=150)

app=Application(root)
root.configure(bg='#e6e9f2')
root.mainloop()

@acw1668 Here is the updated code, can you send me your version updated code

import tkinter as tk

        self.label.place(x=50,y=80)
        self.create_widgets() 
    
caldate1 = " "
caldate2 = " "
    
def calendar_view1():
    def print_sel1():
        global caldate1
        caldate1 = cal1.selection_get()
        label1.config(text = caldate1)
        return caldate1
    
    top1 = tk.Toplevel(root)
    cal1 = Calendar(top1,
