title: Splitting a string into multiple lists
body: <p>How would I go further reducing a list which has been formed using splitlines into smaller lists?</p>
  
  <p>For instance:<br></p>
  
  <p>I have a string such as <code>'abc,def,hij\nklm,nop,qrs\ntuv,wx,yz\n'</code><br>
  Which when using splitlines becomes<br>
  <code>['abc,def,hij' , 'klm,nop,qrs' , 'tuv,wx,yz']</code></p>
  
  <p>How can I then take this and split it up by commas, so that each element is a string element. 
  such as:
  <code>['abc','def','hij'] ['klm','nop','qrs'] ['tuv','wx','yz']</code></p>
