Question $7$: Converting Decimals to Hexadecimals

Design a Python program to convert a decimal number to a hexadecimal

number? To convert a decimal number $d$ to a hexadecimal number is to

find the hexadecimal digits $h_n,h_{n-1},h_{n-2},$dots,$h_2,h_1,$ and $h_0$ such that

$d=h_n{16}^n+h_{n-1}{16}^{n-1}+h_{n-2}{16}^{n-2}+$dots$+h_2{16}^2+h_1{16}^1+h_0{16}^0$

These hexadecimal digits can be found by successively dividing $d$ by

$16$ until the quotient is $0.$ The remainders are $h_0,h_1,h_2,$dots,$h_{n-2},h_{n-1}$ and

$h_n.$
