How to correctly use radioButton in PyQT5 using QtDesinger?

Question

PyQt

There is:
QtDesinger
PyQT - 5
PySide -6
Python - 3.9.2

file.Ui
file.py

I don't understand how to work with radioButton when using QtDesisnger (that is, when designing gui in ui).

Let's say there is this:

and there is such a code

from PyQt5 import uic
from PyQt5.QtWidgets import QApplication

Form, Window = uic.loadUiType("Window.ui")
app = QApplication([])
window = Window()
form = Form()
form.setupUi(window)
window.show()

app.exec_()

What is the correct way to assign the changeOfFishingRod variable the number 0 (let's say the first option) or 1 (let's say the second option)?
