title: Binary to Hexadecimal converter
body: <p>I have written a code to try and convert a 4-bit binary number into Hexadecimal. Only thing is, when I type a value that begins with a '1' it comes up with the conversion, whereas if I type a value that starts with a '0' it doesn't work. Any help?</p>
  
  <pre><code>print ("""Here's how the program will work. You need to get your binary number ready.
          if it is 8 bit, split it into four, because thats how hexadecimal works. Make sure all your conversions
          are slip into '4' bits like this:
          01001101 will turn into:
          0100 ,and then 1101""")
  time.sleep(6)
  print ("""So, for example, the program will ask you for your binary number. Like this:
          Enter your binary number here:
          Then you put in your number, like this:
          Enter your binary number here: 0100
          Lastly, the program will give you your hexadecimal number, then ask you if you would
          like to do another conversion in this area, or end program.""")

  HEXADECIMAL = int(input("Please enter your binary number here:   "))

  <p>You can try to run this code and start with, for example, 0110, but it will not convert. Any help?</p>
