###get_item.py

# coding=utf-8

from django import template
from django.utils.safestring import mark_safe
from django.template.base import resolve_variable, Node, TemplateSyntaxError

register = template.Library()

def key(d, key_name):
return d[key_name]
key = register.filter('key', key)

index.html

{% for i in list %}

　　{{ dict |key i }}

{% endfor %}

不过通过这个取字典，效率很低
