title: Use regex to cut the string begin with specific character?
body: <p>I am processing a flat file, with data in line by line format, like this</p>
  
  <pre><code>... blah blah blah | sku: 01234567 | price: 150 | ... blah blah blah
  </code></pre>
  
  <p>I want to extract the sku field, it is the number with 8 char long. However, I am not sure if I should use split or regex, I am not very good at using regex in python.</p>
