Hello.
I have copied these 2 files of code from a website.
main.py:
from kivy.app import App
from kivy.uix.label import Label
from kivy.uix.boxlayout import BoxLayout
from kivy.clock import Clock
from kivy.properties import StringProperty
import datetime
class Counter_Timer(BoxLayout):
def update(self, dt):
delta = datetime.datetime(2015, 9, 13, 3, 5) - datetime.datetime.now()
self.days = delta.days
hour_string = str(delta).split(',')[1]
self.hours = hours_string.split(':')[0]
self.minuts = hours_string.split(':')[1]
self.seconds = hours_string.split(':')[2].split('.')[0]
return days, hours, minuts, seconds
class Counter(App):
def build(self):
counter = Counter_Timer
Clock.schedule_interval(counter.update, 1.0)
days = StringProperty()
hours = StringProperty()
minutes = StringProperty()
seconds = StringProperty()
return
if __name__ == "__main__":
Counter().run()
There was written:
"Let's add them to the Counter_timer class:"
days = StringProperty()
hours = StringProperty()
minutes = StringProperty()
seconds = StringProperty()
So i added it into the def build. correct place,right?
And i add it myself, but i'm not sure if it's correct or not:from kivy.properties import StringProperty
And here is the next file counter.kv:
<Counter_Timer>:
orientation: 'vertical'
Label:
text: 'Vacation starts in:'
font_size: '46dp'
Label:
text: root.days + ' Days'
font_size: '46dp'
Label:
text: root.hours + ' Hours'
font_size: '38dp'
Label:
text: root.minuts + ' Minuts'
font_size: '30dp'
Label:
text: root.seconds + ' Seconds'
font_size: '22dp'
When i run it, i get this error:
[INFO ] Kivy v1.8.0

What should i do?
