Which library to use to implement OpenAPI

hello,

I'm going to implement many new web microservices. I'm discovering OpenAPI (YAML/JSON Schema), and and I'm enthusiastic about it.

But I'm lost in the existing libraries implementing it. I would like to use Python and I'm familar with flask;

but then... what do you think of:

• connexion: https://github.com/zalando/connexion
• flasgger: https://github.com/flasgger/flasgger
• swagger-ui: https://pypi.org/project/swagger-ui-py
• flask-swagger-ui: https://pypi.org/project/flask-swagger-ui
• flask-restplus: https://flask-restplus.readthedocs.io/en/stable
• flask-rest-api: https://flask-rest-api.readthedocs.io/en/stable
• flask-restful: https://flask-restful.readthedocs.io/en/latest/

can you guide me to use the right promising libraries, with large communities.

Many thanks. Guillaume
