Template Tag Not Working

Please find the code below I am getting an error

code_challenges/templatetags/fairy_extras.py 
from django import template

register = template.Library()

@register.simple_tag
def conjugate_is(elf_count):
    '''Return conjugated verb 'to be' on singular or plural elf counts'''
    if elf_count==1:
        return "is"
    else:
        if elf_count!=1:
            return "are"
code_challenges/templates/code_challenges/list.html 
{% load fairy_extras %}

There {{ num_elf|conjugate_is }} {{ num_elf }} el{{ num_elf|pluralize:"f,ves" }}.

I realize that this is an older post but the reason your template tag isn't working is because you need to remove the 

{{ num_elf | conjugate_is }}.

That is for filtering. When wanting to use a simple tag and pass data into it you need to use the form 

{% my_tag_function variable_to_pass_in %}
