title: Autobiographical number in python?
body: <p>Hey all at stackoverflow!
  I am learning python and need to code a program which checks if a number is autobiographical. EG:
  21200 is autobiographical as it has 2 0's 1 1's 2 2's 0 3's and 0 4's. This is what i have so far:</p>
  
  <pre><code># Autobiographical numbers
  a = input("Number: ")
  abn = 
  if a == abn:
    print(a, "is autobiographical")
  else:
    print(a, "is not autobiographical")
  </code></pre>
  
  <p>as you can see i have left the abn variable open as i dont know exactly how to do it. I think i have to determine length of a with len(a) then use something like </p>
  
  <pre><code>[x[::1] for x in b]
  </code></pre>
  
  <p>but i am not quite sure as i am pretty new to python.
  Thanks,
  A no0b at python.</p>
