from dataclasses import dataclass


@dataclass
class Bean:
    id: str

        Bean(id=2, name="Peruvian"),
        Bean(id=3, name="Hawaiian"),
        ]

import jinja2

t = jinja2.Template('''

{% for bean in beans %}

{% for attr in bean.__dict__.keys() -%}
    
{% endfor -%}

{% endfor %}
{{ attr }}
{{ bean[attr] }}
''')

print(t.render(beans=beans))

{% endfor %}
{{ attr }}
{{ bean[attr] }}
