title: Create lists with different amounts of random numbers
body: <p>I am needing to create lists of random numbers (being either 0 or 1) with different lengths. I need lists with lengths of 10 numbers, 20 numbers, etc. all the way to 500. This is what I have:</p>
  
  <pre><code>import random
  list1 = []
  for x in range(10,501,10):
      list1.append(random.randint(0,1))
      print(list1)
      list1.clear()
  </code></pre>
  
  <p>So I'm getting 50 lists of only one random number. I understand that the range() is my problem because it is only an iterator, so what would I do to avoid writing 50 for loops to get all of these lists?</p>
