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

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()
[here is the reference of the image]1

Suggest to use two StringVar to store the start date and end date, and pass the variable to calendar_view():
def calendar_view(var):
def print_sel():
# update the var
var.set(cal.get_date())
# close the calendar window
top.destroy()
top = tk.Toplevel(root)
cal = Calendar(top, font="Arial 14",selectmode='day',
cursor="hand1", year=2020, date_pattern='y-mm-dd')
cal.pack(fill="both", expand=True)
ttk.Button(top, text="ok", command=print_sel).pack()
# make window a modal window
top.grab_set()
top.wait_window(top)
Then update the creation of the two buttons:
button = tk.Button(root, text = 'Test Start Date', bg='#0073BD',height=1,width=15,padx=5,pady=2, fg="white",
command=lambda: calendar_view(startdate))
button = tk.Button(root, text = 'Test End Date', bg='#0073BD',height=1,width=15,padx=5,pady=2,fg="white",
command=lambda: calendar_view(enddate))
and associate the two variables to the two labels, so that their text are updated whenever the variables are updated:
startdate = tk.StringVar(value="<-Click to select Test Start Date")
label1 = tk.Label(root, textvariable=startdate, padx=10, pady=10, bg="#e6e9f2", font=("calibri",8))
enddate = tk.StringVar(value="<-Click to select Test End Date")
label2 = tk.Label(root, textvariable=enddate, padx=10, pady=10, bg="#e6e9f2", font=("calibri",8))

why is .grid giving me an error when I am trying to move my button

import time
import tkinter as tk
from tkinter import scrolledtext
win = tk.Tk()
win.title("My First Game")
win.configure(bg="black")
win.geometry("640x400")
label = tk.Label(win, text="test", fg="red", bg="black").pack()
canvas1 = tk.Canvas(win, width=130, height=20)
canvas1.pack()
entry1 = tk.Entry(win, font="Helvetica 10")
canvas1.create_window(65, 10, window=entry1)
entry1.insert(0, "Type here")
def shortcut():
Shortcut = tk.Label(win, fg="red", bg="black", text="test2")
Shortcut.pack()
button1 = tk.Button(win, text="Enter", fg="red", bg="black", command=shortcut)
button1.pack()
exit_button = tk.Button(win, text="Quit", padx=4, pady=2, bg="black", fg="red", command=quit)
exit_button.pack()
exit_button.grid(row=0, column=2)
win.mainloop()
Why is this giving me an error? I tried in a separate project with just a black screen and the button and it worked fine. But when I put it in the code above it doesn't work
line 42, in <module> exit_button.grid(row=0, column=2)
_tkinter.TclError: cannot use geometry manager grid inside . which already has slaves managed by pack

As #10Rep mentioned in comment - you can remove grid() to resolve problem with error.
import tkinter as tk
# --- functions ---
def shortcut():
shortcut = tk.Label(win, text="test2")
shortcut.pack()
# --- main ---
win = tk.Tk()
label = tk.Label(win, text="test")
label.pack()
canvas1 = tk.Canvas(win) #, width=130, height=20)
canvas1.pack()
entry1 = tk.Entry(canvas1)
canvas1.create_window(0, 0, window=entry1, anchor='nw')
entry1.insert(0, "Type here")
button1 = tk.Button(win, text="Enter", command=shortcut)
button1.pack()
exit_button = tk.Button(win, text="Quit", command=win.destroy)
exit_button.pack()
win.mainloop()
But I expect that you used grid() to organize two buttons in one line.
Problem is that you can't mix pack() and grid() in one window/frame and I see two solutions:
First is to use only grid() to organize all widgets
import tkinter as tk
# --- functions ---
def shortcut():
shortcut = tk.Label(win, text="test2")
shortcut.grid(row=3, column=0, columnspan=2)
# --- main ---
win = tk.Tk()
label = tk.Label(win, text="test")
label.grid(row=0, column=0, columnspan=2)
canvas1 = tk.Canvas(win) #, width=130, height=20)
canvas1.grid(row=1, column=0, columnspan=2)
entry1 = tk.Entry(canvas1)
canvas1.create_window(0, 0, window=entry1, anchor='nw')
entry1.insert(0, "Type here")
button1 = tk.Button(win, text="Enter", command=shortcut)
button1.grid(row=2, column=0)
exit_button = tk.Button(win, text="Quit", command=win.destroy)
exit_button.grid(row=2, column=1)
win.mainloop()
Second is to put Frame (using pack()) and put buttons inside this frame using grid()
import tkinter as tk
# --- functions ---
def shortcut():
shortcut = tk.Label(win, text="test2")
shortcut.pack()
# --- main ---
win = tk.Tk()
label = tk.Label(win, text="test")
label.pack()
canvas1 = tk.Canvas(win) #, width=130, height=20)
canvas1.pack()
entry1 = tk.Entry(canvas1)
canvas1.create_window(0, 0, window=entry1, anchor='nw')
entry1.insert(0, "Type here")
# - frame with grid -
f = tk.Frame(win)
f.pack()
button1 = tk.Button(f, text="Enter", command=shortcut)
button1.grid(row=0, column=0)
exit_button = tk.Button(f, text="Quit", command=win.destroy)
exit_button.grid(row=0, column=1)
# -
win.mainloop()
or using pack(side=...)
import tkinter as tk
# --- functions ---
def shortcut():
shortcut = tk.Label(win, text="test2")
shortcut.pack()
# --- main ---
win = tk.Tk()
label = tk.Label(win, text="test")
label.pack()
canvas1 = tk.Canvas(win) #, width=130, height=20)
canvas1.pack()
entry1 = tk.Entry(canvas1)
canvas1.create_window(0, 0, window=entry1, anchor='nw')
entry1.insert(0, "Type here")
# - frame with pack(side=...) -
f = tk.Frame(win)
f.pack()
button1 = tk.Button(f, text="Enter", command=shortcut)
button1.pack(side='left')
exit_button = tk.Button(f, text="Quit", command=win.destroy)
exit_button.pack(side='left')
# -
win.mainloop()

How do I use Tkinter buttons to open webrowsers properly?

Everything looks right, but when I run the program the buttons and the websites open at the same time and then the buttons don't work?
import webbrowser
from tkinter import *
from tkinter import ttk
root = Tk()
style = ttk.Style()
open_facebook = webbrowser.open('http://www.facebook.com')
open_google = webbrowser.open('http://www.google.com')
open_yahoo = webbrowser.open('http://www.yahoo.com')
open_youtube = webbrowser.open('http://www.youtube.com')
style.configure("TButton",
font="Serif 18",
padding=10)
main_frame = Frame(root)
main_frame.grid(row=0, columnspan=4)
button_facebook = ttk.Button(main_frame, text='Facebook', command=open_facebook).grid(row=1, column=0)
button_google = ttk.Button(main_frame, text='Google', command=open_google).grid(row=1, column=1)
button_yahoo = ttk.Button(main_frame, text='Yahoo', command=open_yahoo).grid(row=1, column=2)
button_youtube = ttk.Button(main_frame, text='Youtube', command=open_youtube).grid(row=1, column=3)
root.mainloop()

I couldn't manage to make it work with the code you had presented, but I could make it work using lambda in the command portion of the button. This was the only way I could ensure that the web browser didn't open the sites until the buttons were pressed.
import webbrowser
from tkinter import *
from tkinter import ttk
root = Tk()
style = ttk.Style()
style.configure("TButton",
font="Serif 18",
padding=10)
main_frame = Frame(root)
main_frame.grid(row=0, columnspan=4)
button_facebook = ttk.Button(main_frame, text='Facebook', command= lambda:
webbrowser.open('http://www.facebook.com'))
button_google = ttk.Button(main_frame, text='Google', command= lambda:
webbrowser.open('http://www.google.com'))
button_yahoo = ttk.Button(main_frame, text='Yahoo', command= lambda:
webbrowser.open('http://www.yahoo.com'))
button_youtube = ttk.Button(main_frame, text='Youtube', command= lambda:
webbrowser.open('http://www.youtube.com'))
button_facebook.grid(row=1, column=0)
button_google.grid(row=1, column=1)
button_yahoo.grid(row=1, column=2)
button_youtube.grid(row=1, column=3)
root.mainloop()

How to design GUI properly

I'm new to python and I don't understand how do I configure the resolution of the font, I wanted to design it but it keeps on expanding, because of the grid(?), Thanks in advance
Here's my code:
import tkinter
from tkinter import ttk
selection=('Weight','Volume','Length')
length = ('mm', 'cm', 'inches','feet', 'yards', 'meter', 'km', 'miles')
weight=('mg','lb','g','kg','oz','ton')
volume=('ml','l','gal','pt','qt')
#title
window = tkinter.Tk()
window.title("Conversion APP")
window.configure(background='#a1dbcd')
title=tkinter.Label(window,text='Welcome to the Converter APP!', fg="#383a39", bg="#a1dbcd", font=("Helvetica",16))
title.grid(row=0,column=2)
title.config(width=100)
window.geometry("300x200")
#1st
labelOne = ttk.Label(window,text='Enter Value',background='blue')
labelOne.grid(row=1,column=0)
to_be_converted = ttk.Combobox(values=length, width=10)
to_be_converted.grid(row=1, column=2)
#2nd
labelTwo = ttk.Label(window, text="Convert To",background='blue')
labelTwo.grid(row=2,column=0)
converted = ttk.Combobox(values=length, width=10)
converted.grid(row=2, column=2)
#input
userName = tkinter.DoubleVar()
userEntry = ttk.Entry(window, width=5, textvariable = userName)
userEntry.grid(row=1, column=1)
#button to convert
btn = ttk.Button(window, text='Convert!', command=convert_length or convert_weight or convert_volume)
btn.grid(row=1, column=4)
#button to exit
exit= ttk.Button(window, text='Quit', command=exit_converter)
exit.grid(row=2, column=4)
window.mainloop()

AttributeError in Tkinter while working with control variables in radiobuttons

I'm trying to get the value of the radiobutton selcted and storing this int into a varable. It's my first tkinter project, so I'm sorry for my probably stupid mistakes...
from tkinter import *
from tkinter import ttk
select = "A"
def begin():
grand = Tk()
grand.title("Converter")
window.destroy()
frame = Frame(grand)
option = IntVar()
-> AttributeError: 'NoneType' object has no attribute '_root'
grandlabel = Label(frame, text="Choose the grand").grid(row=0, sticky=N, padx=5)
grand1 = Radiobutton(frame, text="Speed", variable=option, value=1, command=sel).grid(row=1, sticky=W)
grand2 = Radiobutton(frame, text="etc", variable=option, value=2, command=sel).grid(row=2, sticky=W)
submitgrand = Button(frame, text="Ok", command=unit).grid(row=3, sticky=W)
frame.pack()
grand.mainloop()
def sel():
global option
global select
select = option.get()
option = StringVar()
def unit():
unit = Tk()
global select
select = grandchosen
if (grandchosen == "Speed"):
Label(unit, text="Test").pack()
else:
Label(unit, text="Test2").pack()
unit.mainloop()
root = Tk()
frame = Frame(root)
welcome = ttk.Label(frame, text="Welcome!").grid(row=0, sticky=N, padx=10, pady=3)
okbutton = Button(frame, text="Ok", width=15, command=begin).grid(row=1, sticky=S, padx=20, pady=30)
frame.pack()
style = ttk.Style()
style.configure("TLabel", foreground="midnight blue", font="Times 19")
root.mainloop()
Would be great to get some help, thank you!
