Program to convert a decimal number to hexadecimal in Python

The python program to convert decimal to hexadecimal using while loop is as follows:

# Owner : TutorialsInhand Author : Devjeet Roy

def decimal_to_hexadecimal(n):
    result = list()
    while n:
        res = n % 16
        n = n // 16
        if res < 10:
            result.append(res)
        else:
            result.append(chr(res+55))
    return result[::-1]


if __name__ == "__main__":
    number = int(input("Enter a number: "))
    ans = decimal_to_hexadecimal(number)
    for i in ans:
        print(i, end="")

The output of python program to convert decimal to hexadecimal using while loop is as follows:

 

PS C:\Users\DEVJEET\Desktop\tutorialsInHand> python code.py
Enter a number: 123
7B

Few important points about this program

1. First we ask the user to enter a number and we convert it to integer data type.

2. Then we call the decimal_to_hexadecimal function which divides the number by 16 and makes it the new number and store the remainders in a list. Finally, we return the list in reversed format.

3. The chr() method is used to get a character,if the provided argument is its ASCII value.

4. In the main body, we have just printed the list elements.
