Django: using form in views

Some way to use forms in views:
blank form or form with some content:
if request.method=='GET':
   form1=SelectForm$request.GET$
else:
   form1=SelectForm

And than we send to form necessary corteges for "select" elements $each cortege include  few two-elements cortege and like as ((,$,$,$,$,$,...,$,$) ):
form1.fields $$'select1'$$ .

choices=$(1,'First'$,$2,'Second'$,$3,'Third'$)

We can get data from form:
datas=
if form1.is_valid:
   datas=form1.cleaned_data
   dd=datas $$'select2'$$

$format of the value "cleaned_data" is dict($ )
