TemplateSyntaxError: Expected token ',' got 'for'

Question

I want to display a block/call mixin only if some condition is true. This is my code:

block details
                - var details = get_coverage_details()
                - var flag_display = all(value == [] for value in details.values())
                if not flag_display:
                    +details(details)

get_coverage_details is some python method in my code, which is getting me the dynamic content.

I am getting an error:

TemplateSyntaxError: expected token ',', got 'for'

The problem seems to be here all(value == [] for value in details.values())

I got this error because I was trying to use a Python method in a Jinja2 template that Jinja2 didn't support (in my case, any(), but I imagine it would also apply to all()).

See @flazzarini's answer here.
