ImportError: cannot import name 'QStringList' in PyQt5

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

from PyQt5.QtCore import QStringList

but it shows this error

C:\Python34\python.exe C:/Users/Suhail/PycharmProjects/FirstProject/Test.py
Traceback (most recent call last):
File "C:/Users/Suhail/PycharmProjects/FirstProject/Test.py", line 3, in <module>
from PyQt5.QtCore import QStringList
ImportError: cannot import name 'QStringList'

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?

In PyQt5, there is no QString and hence no need for QStringList.

Any Qt API that would normally return a QString, will automatically return a Python string instead. Similarly, any Qt APIs that would normally return a QStringList will return a Python list containing Python strings. And the opposite also applies: any Qt API that would normally accept a QString or QStringList will accept the Python equivalents instead.

This is the same as the default behaviour when using PyQt4 with Python 3, or when explicitly setting the API to version 2 using sip.setapi.

For more details, see: Differences Between PyQt4 and PyQt5 in the PyQt5 Reference.
