静的メンバ

STEP: 1 クラスの作成


class employee:
    members = []
    def __init__(self):
        pass
        
    def make(self, number, name):
        member = {
            'number':number
            ,'name':name
        }
        
        self.members.append(member)
    
    def getnum(self,number):
        return self.members[number-1]['number']
    
    def getname(self,number):
        return self.members[number-1]['name']
    

n = int(input())
empobj = employee()

for _ in range(n):
    inp = input().split()
    
    if inp[0] == 'make':
        empobj.make(inp[1],inp[2])
    elif inp[0] == 'getnum':
        print(empobj.getnum(int(inp[1])))
    elif inp[0] == 'getname':
        print(empobj.getname(int(inp[1])))

STEP: 2 コンストラクタ

class employee:
    def __init__(self,number,name):
        self.number = number
        self.name = name
    
    def getnum(self):
        return self.number

        return self.name

members = [employee(0,'init')]
n = int(input())

for _ in range(n):
    array = input().split()
    
    if array[0] == 'make':
        members.append(employee(array[1], array[2]))
    elif array[0] == 'getnum':
        print(members[int(array[1])].getnum())
    elif array[0] == 'getname':
        print(members[int(array[1])].getname())

STEP: 3 クラスのメンバの更新

        self.number = new_number
    
    def change_name(self,new_name):
        self.name = new_name

members = [employee(0,'init')]

n = int(input())

for _ in range(n):
    inputs = input().split()
    
    if inputs[0] == 'make':
        _number = int(inputs[1])
        _name = inputs[2]
        members.append(employee(_number,_name))
        
    elif inputs[0] == 'getnum':
        _number = int(inputs[1])
        _member = members[_number]
        print(_member.getnum())
        
    elif inputs[0] == 'getname':
        _number = int(inputs[1])
        _member = members[_number]
        print(_member.getname())
        
    elif inputs[0] == 'change_num':
        _number = int(inputs[1])
        _new_number = inputs[2]
        _member = members[_number]
        _member.change_num(_new_number)
    
    elif inputs[0] == 'change_name':
        _number = int(inputs[1])
        _new_name = inputs[2]
        _member = members[_number]
        _member.change_name(_new_name)
