设计银行卡类并进行测试，该类有账户名、卡号、余额、状态（是否正常）等属性，并实现存、取、转账等操作。python

设计银行卡类（BankAccount）可以按照面向对象的原则进行，下面是一个简单的Python类实现：

class BankAccount:
    def __init__(self, account_name, card_number, balance=0, is_active=True):
        self.account_name = account_name
        self.card_number = card_number
        self.balance = balance
        self.is_active = is_active

    # 存款方法
    def deposit(self, amount):
        if amount > 0:
            self.balance += amount
            print(f"存款{amount}成功，当前余额为{self.balance}")
        else:
            print("存款金额无效")

    # 取款方法
    def withdraw(self, amount):
        if amount <= self.balance and amount > 0:
            self.balance -= amount
            print(f"取款{amount}成功，当前余额为{self.balance}")
        elif amount == 0:
            print("取款金额为零")
        else:
            print("余额不足，取款失败")

    # 转账方法
    def transfer(self, to_account, amount):
        if amount > 0 and amount <= self.balance:
            self.balance -= amount
            to_account.deposit(amount)
            print(f"向{to_account.account_name}转账{amount}成功，当前余额为{self.balance}")
        else:
            print("转账金额过大或余额不足")

# 测试部分
account1 = BankAccount("张三", "1234567890123456", 1000)
account2 = BankAccount("李四", "9876543210987654", 500)

# 测试存款
account1.deposit(500)
account2.deposit(-200)  # 负数存款示例

# 测试取款
account1.withdraw(200)
account2.withdraw(0)  # 取款金额为零

# 测试转账
account1.transfer(account2, 300)
