各位老师，下午好，麻烦哪位老师有空将这段python代码用易语言写出来，不胜感激，是一个和并查集有关的。

class Person:
    def __init__(self, name):
        self.name = name
        self.children = []

    def add_child(self, child):
        self.children.append(child)

    def __str__(self, level=0):
        result = ' ' * level * 2 + self.name + '\n'
        for child in self.children:
            result += child.__str__(level + 1)
        return result


class FamilyTree:
    def __init__(self):
        self.members = {}

    def get_or_create_person(self, name):
        if name not in self.members:
            self.members[name] = Person(name)
        return self.members[name]

    def add_relationship(self, parent_name, child_name):
        parent = self.get_or_create_person(parent_name)
        child = self.get_or_create_person(child_name)
        parent.add_child(child)

    def display_tree(self):
        # 找到根节点（没有父亲的节点）
        all_children = {child.name for person in self.members.values() for child in person.children}
        roots = [person for name, person in self.members.items() if name not in all_children]

        result = ""
        for root in roots:
            result += str(root)
        return result


# 示例数据
relationships = [
    ("BOM", "1"),
    ("BOM", "2"),
    ("BOM", "3"),
    ("1", "11"),
    ("1", "12"),
    ("1", "13"),
    ("2", "21"),
    ("3", "31"),
    ("31", "311"),
    ("31", "312"),
    ("312","3121")
]

# 创建族谱实例
family_tree = FamilyTree()

# 添加父子关系
for parent, child in relationships:
    family_tree.add_relationship(parent, child)

# 显示族谱
print("族谱：")
print(family_tree.display_tree())
