Answer 1

I think you're looking for macros

Answer 2

You can use macros.

{% macro input(name, value='', type='text', size=20) -%}
    <input type="{{ type }}" name="{{ name }}" value="{{value|e }}" size="{{ size }}">
{%- endmacro %}


<p>{{ input('username') }}</p>
<p>{{ input('password', type='password') }}</p>
