GUI Project Application.

I am a newbie on programming world and I am trying to learn Python as it is the easiest and very strong programming language. I've learnt all basic theories and the programming syntax and then I have solved some problems from urionlinejudge. Now I'am trying to learn GUI Appliations and I am trying to learn Tkinter module of Python.

I watched some tutorials on youtube and I just made my first GUI application. I named it "Simple GUI". This is just a form and all the information you put on this form will store in "simpleGUI.txt" file after clicking on submit button. Let's check out the codes.

Importing tkinter and naming the application

import tkinter as tk
from tkinter import ttk

win = tk.Tk()
win.title('Simple GUI')

nb = ttk.Notebook(win)

page1 = ttk.Frame(nb)
page2 = ttk.Frame(nb)

nb.add(page1, text='ONE')
nb.add(page2, text='TWO')
nb.grid(row=0, column=0)

label_frame1 = ttk.Labelframe(page1, text='Enter your info')
label_frame1.grid(row=0, column=0)

Creating Labels for label_frame1

name_label = ttk.Label(label_frame1, text='Enter your name :')
name_label.grid(row=0, column=0, sticky=tk.W)

email_label = ttk.Label(label_frame1, text='Enter your e-mail :')
email_label.grid(row=1, column=0, sticky=tk.W)

age_label = ttk.Label(label_frame1, text='Enter your age :')
age_label.grid(row=2, column=0, sticky=tk.W)

gender_label = ttk.Label(label_frame1, text='Enter your gender :')
gender_label.grid(row=3, column=0, sticky=tk.W)

Creating Entryboxes for label_frame1

name_var = tk.StringVar()
name_entrybox = ttk.Entry(label_frame1, width=16, textvariable=name_var)
name_entrybox.grid(row=0, column=1)
name_entrybox.focus()

email_var = tk.StringVar()
email_entrybox = ttk.Entry(label_frame1, width=16, textvariable=email_var)
email_entrybox.grid(row=1, column=1)

age_var = tk.StringVar()
age_entrybox = ttk.Entry(label_frame1, width=16, textvariable=age_var)
age_entrybox.grid(row=2, column=1)

gender_var = tk.StringVar()
gender_combobox = ttk.Combobox(label_frame1, width=13, textvariable=gender_var, state='readonly')
gender_combobox['values'] = ('Male', 'Female', 'Other')
gender_combobox.grid(row=3, column=1)
gender_combobox.current(0)

label_frame2 = ttk.Labelframe(page2, text='Enter your info')
label_frame2.grid(row=0, column=0)

Creating label for label_frame2

Type_label = ttk.Label(label_frame2, text='Type ? :')
Type_label.grid(row=4, column=0, sticky=tk.W)

creating radiobtn for label_frame2

usertype = tk.StringVar()
radiobtn1 = ttk.Radiobutton(label_frame2, text='Student', value='Student', variable=usertype)
radiobtn1.grid(row=4, column=1)

radiobtn2 = ttk.Radiobutton(label_frame2, text='Teacher', value='Teacher', variable=usertype)
radiobtn2.grid(row=4, column=2)

creating checkbutton for label_frame2

checkbtn_var = tk.IntVar()
checkbtn = ttk.Checkbutton(label_frame2, text='Check if you want to subscribe our newsletter.', variable=checkbtn_var)
checkbtn.grid(row=5, columnspan=3)

creating Submit button

def action():
    username = name_var.get()
    userage = age_var.get()
    user_email = email_var.get()
    user_gender = gender_var.get()
    user_type = usertype.get()
    check_btn = checkbtn_var.get()
    if user_gender == 'Male':
        he = 'He'
    elif user_gender == 'Other':
        he = 'He'
    else:
        he = 'She'

    if check_btn == 1:
        Subscribed = 'subscribed'
    else:
        Subscribed = 'not subscribed'
    print(
        f'{username}\'s age is {userage}, gender is {user_gender}, email is {user_email}. {he} is a {user_type} and {Subscribed} to our newsletter.')

    with open('simpleGUI.txt', 'a') as f:
        f.write(
            f'{username}\'s age is {userage}, gender is {user_gender}, email is {user_email}. {he} is a {user_type} and {Subscribed} to our newsletter.\n')

    name_entrybox.delete(0, tk.END)
    email_entrybox.delete(0, tk.END)
    age_entrybox.delete(0, tk.END)


submit_button = ttk.Button(win, text='Submit', command=action)
submit_button.grid(row=6, columnspan= 2)

win.mainloop()

So the full code is here

from tkinter import ttk
