Python Odd number maker
<p>python function <code>nthOddDigits</code>, which takes a positive integer x and returns the nth number that only has odd digits 1,3,5,7,9,11, 13, 15, 17, 19, 31 etc. <code>nthOddDigits(0)</code>returns 1, etc.  </p>

<pre><code>def nthOddDigits(x):
    if x % 2 == 0:
       return x + 1

    else:
       return x;`
</code></pre>

<p>This returns odd numbers if inputted number is even.  However, it doesn't check if all the digits are odd.  example <code>nthOddDigits(20)</code> returns 21 which is odd but all the digits aren't odd.  Thanks!</p>
