Using increased/decreased variables in django templates

Maybe it's a little bit stupid question, but I didn't find an answer. Is there any way to use increased/decreased variables in django templates?

e.g.{{ some_variable + 1 }}

Inside for loop use forloop.counter that will automatically increase the counter till the records.

{% for a in object_list %}
{{ forloop.counter }}
{% endfor %}

There's a built-in add filter:

{{ some_variable|add:"1" }}

One way of doing this is by using a django template filter.

https://docs.djangoproject.com/en/dev/howto/custom-template-tags/#writing-custom-template-filters

def inc(value):
    return value+1

and then:

{{ some_variable|inc }}
