At this point, 'Continent' (variables should have lower case names,
see PEP 8) should have the chosen value from the choices.

Continent = form.cleaned_data['Continent']

Continent = dict(form.fields['Continent'])[Continent]

  The obvious confusion stemming from the upper case variable aside, the second line is total nonsense. Drop it and you'll be golden.
