一、简单的依赖方法

import datetime

#依赖
class Project:
    def __init__(self, name, team, start_date):
        self.name = name
        self.team = team
        self.start_date = start_date

    def __repr__(self):
        return f'<Project :{self.name}>'

class Developer:

    def __init__(self, name, skills):
        self.name = name
        self.skills = skills

    def __repr__(self):
        return f'<Developer :{self.name}>'

    def develop_project(self, project):
        print(f'{self.name}正在参与开发项目:{project}')

if __name__ == "__main__":
    d = Developer('Tom', ['Python', 'SQL', 'Flask'])
    print(d)
    proj = Project('OA', 'DEV2', datetime.date(2018, 3, 7))
    d.develop_project(proj)    #依赖 Project的类
