Is PySide and PySide6 the same thing??? When looking at how to use PySide6, the imports in the code include PySide6… are you importing PySide?

Hi Piotr,
Welcome to Python and FCC.

It looks like you installed Pyside6 properly. You are getting: Requirement already satisfied messages, Good!

Commonly, first thing I do with a new python library is research it on https://pypi.org/
try: https://pypi.org/project/PySide6/

Next I went to: https://wiki.qt.io/Qt_for_Python

It looks like you are on the right path.
Just keep reading and keep going.

Yes.

I mean, in your code, are you importing pyside6 or pyside? Could you share your code, is there a github link?

import sys
import random
from PySide import QtCore, QtWidgets, QtGui

class MyWidget(QtWidgets.QWidget):
def init(self):
super().init()

    self.hello = ["Hallo Welt", "Hei maailma", "Hola Mundo", "Привет мир"]

    self.button = QtWidgets.QPushButton("Click me!")
    self.text = QtWidgets.QLabel("Hello World",
                                 alignment=QtCore.Qt.AlignCenter)

    self.layout = QtWidgets.QVBoxLayout(self)
    self.layout.addWidget(self.text)
    self.layout.addWidget(self.button)

    self.button.clicked.connect(self.magic)

@QtCore.Slot()
def magic(self):
    self.text.setText(random.choice(self.hello))

if you installed PySide6, why is your import not:

from PySide6 import QtCore, QtWidgets, QtGui

Your error is saying it can’t find PySide… but you installed PySide6… that’s what I’ve been saying. I’ve never used these packages before, but from what I saw the PySide6 installation and use manual showed the imports are from PySide6.
