state的description要跟它的module的功能相对应,这里应该去掉list的部分;choices也一样
每个参数的定义要准确,如果这个参数是必填的,要注明:required: true,如果有默认值,要注明default:“具体的默认值”

变量之间应该有一个空格进行分割,不然无法通过CI,所以145行应该是:module.fail_json(msg="Failed to delete access_key {0} with error {1}".format(module.params.get('access_key_id'), e))

module.exit_json(changed=changed)

argument_spec 中的参数的定义要跟DOCUMENTATION中的保持一致,如果是required=True,要进行声明,否则不用;如果有choices,要声明,用于做参数合法性校验,如果有default,要声明,为其指定一个初始化的default value;所有的变量的类型要进行声明,具体可参考:https://github.com/ansible/ansible/pull/36898/files#diff-7e74fd025d257f404dbd79c735e2cdd3 这是一个已经提交到官方的并且被官方review过多次的PR

create和delete实现的逻辑没什么大的问题,由于这个module本身功能不是很大,逻辑不复杂,所以个人认为直接在main中实现create和delete就可以了,不用单独定义三个函数,可以避免重复多次的取值和判断的逻辑,同时整体代码看起来也很整洁。
