首先到我們的工程目錄下，敲入:

python manage.py shell

# forloop.counterfrom django.template import Context, Templatet = Template("""    {% for item in our_list %}        <p>{{ forloop.counter }}: {{ item }}</p?    {% endfor %}""")c = Context({‘our_list‘: [x for x in range(10)]})print t.render(c)#forloop.counter0from django.template import Context, Templatet = Template("""    {% for item in our_list %}        <p>{{ forloop.counter0 }}: {{ item }}</p?    {% endfor %}""")c = Context({‘our_list‘: [x for x in range(10)]})print t.render(c)#forloop.firstt = Template("""    {% for object in objects %}        {% if forloop.first %}            <li class="first">        {% else %}            <li>        {% endif %}        {{ object }}</li>    {% endfor %}c = Context({‘objects‘: [x for x in range(10)]})print t.render(c)#forloop.lastt = Template("""    {% for link in links %}{{ link }}{% if not forloop.last %} | {% endif %}{% endfor %}    """)c = Context({‘links‘: [‘link‘+ x for x in range(10)]})print t.render(c)#forloop.parentloopt = Template("""    {% for country in countries %}    <table>    {% for city in country.city_list %}        <tr>            <td>Country #{{ forloop.parentloop.counter }}</td>            <td>City #{{ forloop.counter }}</td>            <td>{{ city }}</td>        </tr>   {% endfor %}   </table>   {% endfor %}""")china = {‘city_list‘: [‘shanghai‘, ‘beijing‘]}usa = {‘city_list‘: [‘xxxx‘, ‘yyy‘]}countries = [china, usa]c = Context(countries)t.render(c)
