Qt Designer/PyQt/Python how to access an element? - qt

Question

Please help. There is a layout ui file. I connected it - I did several manipulations through the Form class. Now I want to create a class with layout change. But I don’t understand how to “reach out” to the element .... I am attaching the code, the ui file too
Converting to py file does not make sense in my case. I ask for help - tell me how can I create a class with what I have and change the elements?

# so it works, but I want to understand - how can I create a class correctly
# form.label_11.setText('erthtzrjnsymzgs')
