Factorial Number in Tkinter Python

Factorial number in tkinter python. This program will print the factorial number in the new windows as an output Tkinter python gui program. The product of all positive integers less than or equal to a particular positive integer, represented by that integer and an exclamation point in mathematics. As a result, factorial seven is expressed as 7!, which means 1 2 3 4 5 6 7. The factorial zero is equal to one. In the assessment of permutations and combinations, as well as the coefficients of terms in binomial expansions, factorials are frequently encountered.

Resolution in GUI

The number of pixels in a digital picture or display is measured in resolution. It’s calculated as W x H, where W denotes the amount of horizontal pixels and H is the number of vertical pixels. An HDTV, for example, has a resolution of 1920 x 1080 pixels.Using this program we can execute factorial number in tkinter python.

Import Tkinter GUI in Python

The practise of importing allows Python code in one module to access code in another module. The import statement does two tasks: it looks for the named module and then binds the results to a name in the local scope.

Tk.Button in Python

Tkinter is a Python library that includes a number of functions and methods for building applications. To make a tkinter application, we usually create a tkinter frame, which is TkInterFrame (). It assists in the display of the root window and manages the rest of the tkinter application’s components.

import tkinter as tk
from tkinter.colorchooser import * 
def factorial(n): 
return 1 if (n==1 or n==0) else n * factorial(n - 1); 
def calculate():
result=factorial(int(entryText.get()))
info.config(text=result) 
mw = tk.Tk()
mw.title('Inlarn.com')
mw.geometry("200x200") 
mw.resizable(0, 0) 
entryText = tk.Entry(text=1, bg='white', fg='black')
entryText.place(x = 50, y = 25, width=100, height=25) 
btn = tk.Button(text='Calculate', command=calculate)
btn.place(x = 50, y = 75, width=100, height=25) 
info = tk.Label(text='result', bg='white', fg='black')
info.place(x = 50, y = 125, width=100, height=25) 
mw.mainloop()
