I have simple django form:

```
class AddSymbolForm(forms.Form):
    list_n = forms.ChoiceField(choices=[(1,1), (2,2), (3,3)]) 

```

How can I set initial value in views.py? 

I tried to something like this:

```
add_symbol_form = AddSymbolForm(initial={list_n:3})

```

And this is not working. So is there any way I can set initial values for choice fields? 

P.S. It's interesing but this code set correct initial value

```
class AddSymbolForm(forms.Form):
    list_n = forms.ChoiceField(choices=[(1,1), (2,2), (3,3)], initial=3)

```

and this one is not working correctly:

```
class AddSymbolForm(forms.Form):
    list_n = forms.ChoiceField(choices=[(1,1), (2,2), (3,3)])
    list_n.initial = 3

```
