如何在不实例化的情况下从对象填充项目列表

class Project:
    def __init__(self, name, description, created_date):
        self.name = name
        self.description = description
        self.created_date = created_date

class ProjectList:
    @staticmethod
    def populate_projects():
        projects = []
        # 从数据源获取项目信息，这里使用示例数据
        project_data = [
            {"name": "Project 1", "description": "Description 1", "created_date": "2022-01-01"},
            {"name": "Project 2", "description": "Description 2", "created_date": "2022-02-01"},
            {"name": "Project 3", "description": "Description 3", "created_date": "2022-03-01"}
        ]
        
        # 创建项目对象并添加到项目列表中
        for data in project_data:
            project = Project(data["name"], data["description"], data["created_date"])
            projects.append(project)
        
        return projects

# 调用填充项目列表的方法
projects = ProjectList.populate_projects()

# 打印项目列表
for project in projects:
    print("Name:", project.name)
    print("Description:", project.description)
    print("Created Date:", project.created_date)
    print()
