title: Unorderable types: int() < list()
body: <pre><code>next_number = []
  
  for i in range(len(fib)):
  
      while next_number &lt; [10]:
          next_number = fib[i] + fib[i + 1]
          fib.append(next_number)
  
  print(next_number)
  
  Traceback (most recent call last):
  File "&lt;pyshell#11&gt;", line 1, in &lt;module&gt;

  while next_number &lt; limit:
  TypeError: unorderable types: int() &lt; list()

  <p>Why he gives me this error because next_number is list and [10] is also a list.</p>
