Eli's answer is correct if you have installed PyQt4. You are probably looking at an example that uses PyQt3, which had a qt module you could import. — Michael Greene

The current PyQt comes in the PyQt4 package, which has several modules. You almost always need to start with:

from PyQt4 import QtCore
from PyQt4 import QtGui

Add other imports as necessary if you need additional sub-modules of PyQt (like QtNetwork, QtSql etc).

Tip for the future: find the lib/site-packages library of your Python installation and look at the packages in there if you're not sure about the name after installing.

Also, arm yourself with a PyQt tutorial - any decent one covers this in the first few paragraphs.

Also, from PyQt4 import Qt. Contains the most commonly-used classes and is shorter to type.

@delnan: I must confess that personally I import * when using PyQt because all classes start with Q anyway, and it really saves a lot of typing for large amounts of code

import PyQt4 doesn't suffice to make sure that PyQt has been successfully linked to a working Qt installation. Either can be broken (linking or the Qt installation). Doing from PyQt4 import QtGui does expose such issues, e.g., dlopen failures.
