Python/Kivy KeyError

Question

I faced this problem: KeyError: 'city'. I get data from my database and put this data in dictionary. My code: Main.py

for row in rows:
    city_dict = {'city': row[2]}
    C = ClinicBanner(city=city_dict['city'])
    result_banner.add_widget(C)

Clinicbanner.py

class ClinicBanner(GridLayout):
    rows = 1
    def __init__(self, city, **kwargs):
        super(ClinicBanner, self).__init__(**kwargs)

        centre = FloatLayout()
        centre_button = Button(text=kwargs['city'], size_hint=(1, .8), pos_hint={"top": .2, "left": 1})
        centre.add_widget(centre_button)

        self.add_widget(centre)

And I got this error: line 14, in init centre_button = Button(text=kwargs['city'], size_hint=(1, .8), pos_hint={"top": .2, "left": 1}) KeyError: 'city'

I really hope that you can help me. Thank you for your answers!

Answer 1

You have defined the city argument in the init method:

def __init__(self, city, **kwargs):

Why do not use it:

centre_button = Button(text=city, size_hint=(1, .8), pos_hint={"top": .2, "left": 1})
