Custom validation error

I am getting error with the code. Do I have to use regex for this and if i have to, then do i import re too?

myproject/forms.py 
from django import forms

def not_treehouse(str):
    s = str.lower()
    if(s.endswith("@teamtreehouse.com")):
        raise ValidationError("teamtreehouse member")

class LeadShareForm(forms.Form):
    email = forms.EmailField()
    link = forms.URLField()
    honeypot = forms.CharField(widget=forms.HiddenInput, required=False)

    def clean_honeypot(self):
        honey = self.cleaned_data['honeypot']
        if len(honey):
            raise forms.ValidationError('Bad robot!')
        return honey

You should apply the function to the below form by adding "validators=[not_treehouse]" to the honeypot field. BTW, I used the following method: def not_treehouse(value): value_lower = value.lower() if "@teamtreehouse.com" in value_lower: raise forms.ValidationError("The email is from Treehouse")
