Here's my thought on Show some equivalent list comprehensions in filter examples · Issue #1068 · pallets/jinja

I often want to reach for non existing list comprehensions in jinja 2, Here are a few nice equivalents.

a: {{ data | selectattr('x', 'gt', 5) | list }}
b: {{ data | map(attribute='c') | list }} 
c: {{ data | selectattr('x', 'gt', 5) | map(attribute='c') | list }}
