GitLab API - 批量修改项目开放级别（python）

Project visibility level

• private: Project access must be granted explicitly for each user.

• internal: The project can be cloned by any logged in user.

• public: The project can be accessed without any authentication.

背景：GitLab上有一个Group，开放级别是internal，id是4；在这个Group下有几十个subgroup，开放级别也都是internal；每个subgroup下有若干个project ，开放级别有internal也有private。现在想将这些project的开放级别全都改成internal。
