django模板系統學習筆記之for 在for標籤裏面，有以下知識點: forloop.counter forloop.counter0 forloop.first forloop.last forloop.revcounter forloop.revcounter0 froloop.parentloop
empty
下面我們舉例學習:
首先到我們的工程目錄下，敲入:
python manage.py shell
# forloop.counter
from django.template import Context, Template
t = 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.counter0
from django.template import Context, Template
t = 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.first
t = 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.last
t = 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.parentloop
t = 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)
