Tkinter yordamida bir toyifali o'lchovlar uchun konvertor oynasini tashkil etish

Tkinter yordamida bir toyifali o'lchovlar uchun konvertor oynasini tashkil etish.

Python GUI (grafik foydalanuvchi interfeysi) ni ishlab chiqish uchun bir nechta variantlarni taklif etadi. Barcha GUI usullaridan tkinter eng ko'p ishlatiladigan usul hisoblanadi. Bu Python bilan ta'minlangan Tk GUI asboblar to'plamiga standart Python interfeysi. Tkinterli Python GUI dasturlarini yaratishning eng tezkor va eng oson usulini chiqaradi. Tkinter yordamida GUI yaratish oson ish.

Tkinter yaratish uchun:

1. 
   Modulni import qilish - tkinter
   
2. 
   Asosiy oynani (konteyner) yarating
   
3. 
   Asosiy oynaga istalgan miqdordagi vidjetni qo'shing
   
4. 
   Vidjetlarda Trigger tadbirini qo'llang.
   

Python Tkinter moduli yordamida GUI asosidagi oddiy konvertor yarataylik, u asosiy arifmetik amallarni qo'shish, ayirish, ko'paytirish va bo'lishni bajarishi mumkin.

Quyida amalga oshirish:

from tkinter import *

window = Tk()

window.title("Converter")

window.geometry("500x300+500+350")

'Micrometer':0.000001, 'Mile':1609.35, 'Yard':0.9144, 'Foot':0.3048,

'Inch':0.0254}

return val*SI[unit_in]/SI[unit_out]
