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

 1 class Employee:
 2     def __init__(self, name, age, sex, partment):
 3         self.name = name
 4         self.age = age
 5         self.sex = sex
 6         self.partment = partment
 7 
 8     def __hash__(self):
 9         return hash("%s%s" % (self.name, self.sex))
10 
11     def __eq__(self, other):
12         if self.name == other.name and self.sex == other.sex:
13             return True
14 
15 
16 employee_list = []
17 for i in range(250):
18     employee_list.append(Employee('Aqiu', i, 'nan', 'python'))
19 for i in range(250):
20     employee_list.append(Employee('qiu', i, 'nan', 'java'))
21 for i in range(250):
22     employee_list.append(Employee('A', i, 'nv', 'c++'))
23 for i in range(250):
24     employee_list.append(Employee('iu', i, 'nv', 'python'))
25 
26 employee_set = set(employee_list)
27 for person in employee_set:
28     print(person.__dict__)
