What will be the output of the following ModelForm code?

from django import forms
from django.db import models

class User(models.Model):
    name = models.CharField(max_length=100)
    email = models.EmailField(unique=True)
    age = models.IntegerField()

class UserForm(forms.ModelForm):
    class Meta:
        model = User
        fields = ['name', 'email']

form = UserForm()
print(len(form.fields))
