Strange Django session KeyError

Question

I am learning to use sessions in Django. Here is simple code that I wrote. It was working yesterday, however, I keep getting KeyErrors 'score' today. Where is the problem?

def home(request): request.session.get('score',0) if request.GET.get('add'): request.session['score'] += 1 if request.GET.get('restart'): request.session['score'] = 0 return render_to_response('home.html', {'zero':request.session['score']})

I had the same issue with my code. It is weird though why it works in the beginning and it doesn't work after a while. No code has been changed. — user7993009

Change request.session.get('score',0) to request.session.setdefault('score',0).
