predictions.py

from collections import namedtuple
from wtforms import Form, IntegerField, FieldList, FormField, TextField
from werkzeug.datastructures import MultiDict

Prediction = namedtuple('Prediction', ['id'])

predictions = [Prediction(id=1), Prediction(id=2)]

class PredictionForm(Form):
    id = IntegerField()
    home = TextField()
    away = TextField()

class PredictionListForm(Form):
    predictions = FieldList(FormField(PredictionForm))

form = PredictionListForm(data=MultiDict({'predictions': predictions}))

print form.predictions()

This is the result
