python - 在 django 模板中使用循环，就像在 python 中使用它们一样

Question

我可以在 django 模板中做这样的事情吗？:

firstList = ["foo", "bar"]
secondList = ["foo", "bar"]
for counter_one, _firstList in enumerate(firstList):
  for counter_two, _secondList in enumerate(secondList):
    if firstList[counter_one] == secondList[counter_two]:
      print(firstList[counter_one])

因为如果我能的话那就太棒了:D

Answer 1

>>> from django.template import Template, Context
>>> t = Template('''
...     {% for first in firstList %}
...         {% for second in firstList %}
...             {% if first == second %}
...                 {{ first }}
...             {% endif %}
...         {% endfor %}
...     {% endfor %}
... ''')
>>> t.render(Context({'firstList': ['foo', 'bar'], 'secondList': ['foo', 'bar']}))
u'\n    \n        \n            \n                foo\n            \n        \n            \n        \n    \n        \n            \n        \n            \n                bar\n            \n        \n    \n'
>>> print(t.render(Context({'firstList': ['foo', 'bar'], 'secondList': ['foo', 'bar']})))


                foo



                bar

如果您需要内循环的索引，请使用fooloop.counter0或forloop.counter。 (从 0 开始，从 1 开始)。请参阅for template tag .

顺便说一句，代码不需要索引，因为代码只打印列表的元素。
