Startswith Template Filter

example.html

{% load startswith %}

<li{% if request.path|startswith:'/settings/' %} class="active"{% endif %}>

startswith.py

from django import template

register = template.Library()


@register.filter('startswith')
def startswith(text, starts):
    if isinstance(text, basestring):
        return text.startswith(starts)
    return False

where i have to place "startswith.py" ?
pycharm can`t find it near admin.py, models.py and etc.
