I think there is a typo in the code. In item.parent.text(0) should be item.parent().text(0)

I wasted days trying to learn how to extract the data from a treewidget, and the last 2 minutes of your video got me out of my doubt. Can you share the code with me? thank you very much

Very interesting video, I am interested in your use of XML. I am currently coding a qt5 C++ application with a tree widget and table widget :). I have always wanted to learn Python. Happy coding.
