#1

✅PYTHON PROGRAM TO CONVERT DECIMAL TO HEXADECIMAL USING WHILE LOOP

conversion_table = ['0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F']
decimal = int(input("Enter a number:"))
hexadecimal = ''
while(decimal>0):
    remainder=decimal%16
    hexadecimal=conversion_table[remainder]+hexadecimal
    decimal=decimal//16
print("Hexadecimal:",hexadecimal)

✅HOW TO REMOVE IMAGE BACKGROUND USING PYTHON LIBRARY -REMBG?

from rembg import remove
from PIL import Image
import easygui as eg
input_path = eg.fileopenbox(title=’Select image file’)
output_path = eg.filesavebox(title=’Save file to..’)
input = Image.open(input_path)
output = remove(input)
output.save(output_path)

✅WRITE A PYTHON PROGRAM TO FIND FACTORIAL OF A GIVEN NUMBER USING FUNCTIONS

Code:

def fact(n):
 return 1 if (n==1 or n==0)else n*fact(n-1)
num=5
print("Factorial of ",num,"is")
fact(num)
