title: ImportError: cannot import name 'QStringList' in PyQt5
body: <p>I am using PyQt5 but can't import QStringList. I know that QStringList used to be in the module QtCore in PyQt4. So I try importing the class using</p>
  
  <pre><code>from PyQt5.QtCore import QStringList
  </code></pre>
  
  <p>but it shows this error</p>
  
  <pre><code>C:\Python34\python.exe C:/Users/User/PycharmProjects/FirstProject/Test.py
  Traceback (most recent call last):
  File "C:/Users/User/PycharmProjects/FirstProject/Test.py", line 3, in &lt;module&gt;
  from PyQt5.QtCore import QStringList
  ImportError: cannot import name 'QStringList'
  </code></pre>
  
  <p>I am using PyCharm and it shows in auto-completion something called QStringListModel. I was following the book "Rapid GUI Development with Python and Qt" by Mark Summerfield. How do I use QStringList, or anything else in PyQt5 that will do the job of QStringList?</p>
