hash算法的移到面试题

一家公司的员工管理系统,记录员工姓名,性别,年龄,部门,若员工内部转岗 例如python开发转到go开发,产生新的记录,姓名,性别,年龄,新的部门

假设有一千个员工,如果几个员工的姓名和性别相同,那么认为是同一个员工,请对这一千个员工去重

class Employee:
    def __init__(self, name, age, sex, partment):
        self.name = name
        self.age = age
        self.sex = sex
        self.partment = partment

    def __hash__(self):
        return hash("%s%s" % (self.name, self.sex))

    def __eq__(self, other):
        if self.name == other.name and self.sex == other.sex:
            return True


employee_list = []
for i in range(250):
    employee_list.append(Employee('Aqiu', i, 'nan', 'python'))
for i in range(250):
    employee_list.append(Employee('qiu', i, 'nan', 'java'))
for i in range(250):
    employee_list.append(Employee('A', i, 'nv', 'c++'))
for i in range(250):
    employee_list.append(Employee('iu', i, 'nv', 'python'))

employee_set = set(employee_list)
for person in employee_set:
    print(person.__dict__)
