Django template filter for numbers

Question

I need such Django template filter:

1 > 01
2 > 02
10 > 10

Do you understand? I want to make 2 min length of the number.

Answer 1

Perfect use case for stringformat built-in filter:

{{ value|stringformat:"02d" }}

Demo:

>>> from django.template import Template, Context, loader
>>> values = [1, 2, 10, 100]
>>> c = Context({'values': values})
>>>
>>> t = Template("""
... {% for value in values %}
...     {{ value }}, {{ value|stringformat:"02d" }}
... {% endfor %}""")
>>> print t.render(c)
    1, 01
    2, 02
    10, 10
    100, 100
