django slice numbers in template - django

Question

Is there a way to get multiple digits of a given number within a django template?
For example:
{{ some_num|get_digit:2 }}
will give you the second right most digit. For 1224531 it would be 3
Is there a way to get the last 3 digits or the first 5 digits? Like python's slicing?
something like:
{{ some_num|get_digits:2,5}}

Answer 1

There is a the "slice" template tag
https://docs.djangoproject.com/en/dev/ref/templates/builtins/#slice
It uses the same syntax as Python's list slicing.
Example:
{{ some_list|slice:":2" }}
in python this is equivalent to:
some_list[:2]
BTW your 2nd example would be "2:5" not "2,5"
NB. Python slicing works on any 'sequence'. Strings and lists are sequences. Numbers are not!

Answer 2

any extra filter that converts the number into a string before slicing will work. I used these variants:
{{ some_num|slugify|slice:"2:5" }}
and
{{ some_num|stringformat:"d"|slice:"5:10" }}

Answer 3

{{1234567|make_list|slice:'2:5'|join:''}}
Stefano's answer is on the right track. You need a pre-processing step to turn your number into a list, and a post-processing step to merge that list back into string.

Answer 4

You just need to write code as follow for slicing :-
{{valueformoney|slice:"0:4"}}
{% for cloth in valueformoney|slice:"0:4" %}
<div class="product h-100 w-100 border rounded ">
<div class="img__container">
<img src="{{cloth.cloth_image.url}}" alt="" />
</div>
<div class="product__bottom">
<div class="price">
<span class="text-danger"> <del>{% min_price cloth as result %} {{ result|rupee}}</del></span>
<span>{% discount_price cloth as result %}{{result|rupee}}</span>
<span class="float-right badge p-3 badge-info">Save {{cloth.cloth_discount}}% </span>
</div>
<h3 class="p-4">{{cloth.cloth_name}}</h3>
<div class="button">
