When I enter a decimal integer the program should display the corresponding hexadecimal value.

And this is what I got so far.....

decimal = eval(input("Enter an integer: "))
   
n = decimal

while n != 0:  
    if n % 16 == 10:
        hexadecimal = 'A'
    elif n % 16 == 11:
        hexadecimal = 'B'
    elif n % 16 == 12:
        hexadecimal = 'C'
    elif n % 16 == 13:
        hexidecimal = 'D'
    elif n % 16 == 14:
        hexadecimal  = 'E'
    elif n % 16 == 15:
        hexadecimal = 'F'
    else:
        hexadecimal = n % 16
    
    hexadecimal = hex(n)
    

print("The", str(n) + "its corresponding to", hexadecimal)

For example decimal of 15 will be F (hex)
29 will be 1D (hex)

Apparently, my code is not working.

can anyone help!

Im no expert but I did notice you are in an infinite while loop. Since your code does nothing to modify n, n will always not equal 0. Also, I noticed your using the hex() function anyway so... why not just take the string the user inputs, convert it to an int and then use the hex() functions?

decimal = input('Please type an integer: ')
hexadecimal = hex(int(decimal))

print(decimal + ' is equivlent to ' + hexadecimal)

If im missing something please let me know. Im just not sure why you want to go through all that extra code when you use hex() anyway.

I have to use the loop, and I don't know how to use a loop to write a decimal to hexadecimal code.

Sorry for the delay, I figured your problem had been solved since you didnt answer for a while.
So if you HAVE to use a loop and your code needs to turn a decimal number into hex then...

#Declaring all my global variables here
decimal = ''
hexadecimal = ''
answer = ''
playAgain = True #Assigned true at the begining so program will run.

#Beginning of Program
print('Welcome! Please enter a number you would like converted into hexadecimal: ')
decimal = input()

while playAgain = True:
    hexadecimal = hex(int(decimal)) #Assign the variable hexadecimal the value of the conversion of the integer decimal.
    print(decimal + ' is equivlent to ' + hexadecimal)
    print('Would you like to try again? (y/n)')
    answer = input().lower()

#Now that the program is finished, lets see if the user is done.
    
    if answer != 'y' or 'yes':
        playAgain = False #If the user enters anything other than 'y' or 'yes', playAgain turns to False. Ending the while loop.

Im at work so I have no way to test this code. But that's the idea.
Hope this helps!
