title: how to convert list to string ignoring other characters in python?
body: <p>I have a list like <code>["['a', 'b', 'c', 'd']", '109']</code> with array,numbers inside a list. 
  How do I convert it to the string <code>"abcd"</code>?
  I have done <code>out = ' '.join(row)</code>, which removes commas. I am new to Python.</p>
