Decimal to Hex decimal conversion Program code:

#The following method is used to convert
#decimal integer to hexadecimal 
def decToHexConversion(n):
  hex_digits = []
  while n > 0:
    rem = n % 16
    hex_digits.append(rem)
    n //= 16

  hex_value = "".join(["0" + hex(d)[2:] for d in hex_digits])
  return hex_value

#The main method is used to  prompts the user to enter a decimal integer 
#call the method, decToHexConversion and display result
def main():

  decimal_integer = int(input("Enter a decimal integer: "))
  hexadecimal_value = decToHexConversion(decimal_integer)
  print("The hexadecimal value of {} is {}".format(decimal_integer, hexadecimal_value))
if __name__ == "__main__":
  main()

Executed Output:

Enter a decimal integer: 5678
The hexadecimal value of 5678 is 0e020601
