Hi! i need some help with a program in python on Raspberry pi3.

every time i run the program i get this messeage:

Traceback (most recent call last):
  File "smartmirror.py", line 159, in get_weather
    temprature2 = "%S%S" % (str(int(weather_obj['currently']['temperature'])),
degree_sign)
KeyError: 'currently'
Error: 'currently'. Cannot get weather.

How do i fix that?

Here is the program:
