`from x import y` vs. `from x.y import *`

Question

What is the difference between these two lines?

from PyQt4 import QtGui
from PyQt4.QtGui import *

The first line is \"import QtGui class fr

Answer 1

Packages may export more than one thing. The difference is that the first line imports a single object from the package, the second imports everything. If the package you are importing only exports one thing, the two are synonymous.
