我需要家长Id求和孩子的金额，孩子求和孩子的金额，以此类推

class FamilyMember:
    def __init__(self, name, amount):
        self.name = name
        self.amount = amount

parent = FamilyMember("家长", 100)
child1 = FamilyMember("孩子1", 50)
child2 = FamilyMember("孩子2", 30)

def calculate_total_amount(*family_members):
    total_amount = 0
    for member in family_members:
        total_amount += member.amount
    return total_amount

parent_total = calculate_total_amount(parent)
child1_total = calculate_total_amount(child1)
child2_total = calculate_total_amount(child2)

print("家长的金额总和：", parent_total)
print("孩子1的金额总和：", child1_total)
print("孩子2的金额总和：", child2_total)
