Запуск приложения при ошибке
У меня есть приложение, в котором есть погода, которая берется с OpenWeatherMap.
Как сделать так, чтобы при ошибке с OpenWeatherMap (превышен лимит запросов) и при выключенном интернете приложение все равно открывалось?
Вот ссылка на само приложение: https://github.com/ivapop1/Weather-PyQt5
Вот скрин ошибки при отсутствии интернет соединения:

class WeatherData(QThread):
req = weather.today()
Вот тут ошибка. Класс не инициализируется без первого запроса!
Выстави умолчания совместимого типа:
class WeatherData(QThread):
req = {} # тут можно None
temp = 0
#и тд..
Оно в интерфейсе покажет 0, и через мгновение обновится. Начни с этого.
Дальше напиши стек с виджетом "загрузка" и поставь его пока not req выше погоды. Потом изучай на сигналы-слоты - это основа qt.

1 . Вам надо переделать модуль root.ui
<?xml version="1.0" encoding="UTF-8"?>
<ui version="4.0">
<class>from</class> ??? from
<widget class="QWidget" name="from"> ??? from
<property name="geometry">
<rect>
<x>0</x>
<y>0</y>
<width>370</width>
<height>535</height>
...
from - это зарезервированное слово и абы как и абы где
его использовать нельзя !!!
Я его конвертировал pyuic5 root.ui -o root_ui.py -x
и вручную поправил и использовал в приложении !!!
# vvvvvvv
class Ui_Form(object):
# vvvv
def setupUi(self, Form):
# vvvv
Form.setObjectName("Form")
Form.resize(370, 535)
...
2 . Обратите ВНИМАНИЕ !!!
В модуле weather.py
...
print(f'\n\n def today(): g = {g.ok} ') # +++
if not g.ok: # +++
return False # +++
...
print(f'def week(): g = {g.ok}') # +++
if not g.ok: # +++
return False # +++
...
когда нет коннекта возвращаем False
В модуле main.py
...
if req_week and req: # !!!
self.week = req_week
self.temp = req['temp']
self.feels = req['feels']
self.pres = req['pressure']
self.speed = str(req['wind']['speed'])
self.city = req['city']
self.type = req['dis']
else:
self.mySignal.emit()
...
3 . и другие нужные вещи по тексту.
