使用递归在家族树上卡住

class FamilyMember:
    def __init__(self, name, children=None):
        self.name = name
        self.children = children if children else []

def traverse_family_tree(member):
    print(member.name)
    for child in member.children:
        traverse_family_tree(child)

# 示例家族树
grandparent = FamilyMember("Grandparent")
parent1 = FamilyMember("Parent 1")
parent2 = FamilyMember("Parent 2")
child1 = FamilyMember("Child 1")
child2 = FamilyMember("Child 2")

grandparent.children = [parent1, parent2]
parent1.children = [child1]
parent2.children = [child2]

# 遍历家族树
traverse_family_tree(grandparent)
