NameError: name 'Qt' is not defined

Hello I am searching for circular imports in my code and I try to avoid them and debug the code but I face this error:

File "code.py", line 535, in __init__
   sharedLayout.setAlignment(Qt.AlignTop | Qt.AlignLeft)
NameError: name 'Qt' is not defined

I have imported PyQt5...What is this?

Hi,

If you did just:

import PyQt5

Then it won't be able to find the Qt namespace because you only made the PyQt5 namespace available.

john_hobbyist

Yes but if I write

from...import....

I get circular imports! What should I do?

SGaist

Use the fully qualified name.

How do you create circular imports by using PyQt5 ?

john_hobbyist

This is what I am trying to find out. What is the command of what you are writing?

@john_hobbyist
Which circular imports where?

You can do this from PyQt5:

from PyQt5.QtCore import Qt

and then your original code should work.

In fairness, it is a bit complicated. https://stackoverflow.com/questions/39316693/how-to-import-from-qt-namespase-qt5-python3-x, the solution there, describes the situation and why this works, if you care.

PyQt5.QtCore.Qt.Whatever

Or more simply:

from PyQt5.QtCore import Qt

and then use Qt.
