Почему не запускается код в PyCharm?

Question

При запуске кода выводятся две ошибки. Их я отметил в коде как "#<<<---------ERROR"

Traceback (most recent call last):

File "C:\Users\Захар\Desktop\Часы\watch_s.py", line 309, in

w = ManinWindow()

File "C:\Users\Захар\Desktop\Часы\watch_s.py", line 101, in init

self.setupUi(self)

File "C:\Users\Захар\Desktop\Часы\watch_s.py", line 70, in setupUi

self.layout_t = QGridLayout(self.tab_3)

AttributeError: 'ManinWindow' object has no attribute 'tab_3'. Did you mean: 'tab_2'?

Уточняю ошибку на линии 70. Мне нужна именно "tab_3", но не "tab_2"

Answer 1

Ты сначала исспользуешь переменную, а затем инициализируешь

    self.layout_timer = QGridLayout(self.tab_3) #use но таб3 ещё не существует                        #<<<<<<<<<<<<<<<<--ERROR
    self.layout_timer.addWidget(self.label_3, 0, 0, 1, 2)

    self.tabWidget.addTab(self.tab_2, "")
    self.tab_3 = QtWidgets.QWidget() #init

то есть это что то вроде

...
result=x-1
x=10
...

то есть перенеси инициализацию tab_3 в начало функции, по крайней мере до первого использования
