title: split string until a 5-7 digit number is found in python
body: <p>I have strings like the following:</p>
  <pre><code>1338516 -...pair - 5pk 1409093 -...re Wax 3Pk
  1409085 -...dtnr - 5pk 1415090 -...accessories
  490663 - 3 pack 1490739 -...2 - 3 pack
  </code></pre>
  <p>What I'm trying to do is, split these strings so that the first string is <code>1338516 -...pair - 5pk</code> and the second one is <code>1409093 -...re Wax 3Pk</code>.</p>
  <p>Currently, I'm able to extract the numbers using the following code:</p>
  <pre><code>list(filter(lambda k: '...' in k, reqText))
  lst1 = ''.join(lst)
  numbers = re.findall(r'\d+', lst1)
  numbers1 = [x for x in numbers if len(x) &gt; 3]
  </code></pre>
  <p>Any suggestions?</p>
