Error loading location on openweathermap via API with Kivy

[Gigux]

I can't print data: it does not come out in the python file but I think is defined via json after querying the openweather site. In theory the line cities = ["{} ({})".format(d['name'], d['sys']['country']) for d in data['list']] should print a list of cities similar to the query typed in the search box, so there are two hits for Vancouver, on in the US and one in Canada. The IDE is also flagging the variable request in search_location because it is never used.
