from tkinter import *

# method that performs the action
def action ():
    # getting the user name
    name = entryName.get ()
    
    # Getting the user age
    age = int(entryAge.get())
    # Testing age value
    if age < 18:
        lblResult['text'] = "Welcome : " + name + " You are minor ! "
    else : 
        lblResult['text'] = "Welcome : " + name + " You are major ! "
    
# creation of the main window
root = Tk ()
root.geometry ("475x200")

# Creation of the first entry input field with the associated label
lblName = Label (root, text = "Enter your name")
lblName.place (x = 50, y = 20)
entryName = Entry (root)
entryName.place (x = 230, y = 20 , width = 200)

# Create a label and an entry to get age value
lblAge = Label (root, text = "Enter your age :")
lblAge.place (x = 50, y = 50)
entryAge = Entry (root)
entryAge.place (x = 230, y = 50 , width = 200)

# Create a label to display result
lblResult = Label (root, text = "..............................................")
lblResult.place (x = 230, y = 80)
# Creatie a button that validates the action
Validate = Button (root, text = "Validate", command = action)
Validate.place (x = 230, y = 120, width = 200)
                
root.mainloop ()
