python银行管理系统代码

以下是一个简单的 Python 银行管理系统代码，包括创建账户、存款、取款和查询余额功能：

class BankAccount:
    def __init__(self, name, balance=0.0):
        self.name = name
        self.balance = balance
    
    def deposit(self, amount):
        self.balance += amount
        print("Deposit successful. New balance is:", self.balance)
    
    def withdraw(self, amount):
        if amount > self.balance:
            print("Insufficient balance.")
        else:
            self.balance -= amount
            print("Withdrawal successful. New balance is:", self.balance)
    
    def check_balance(self):
        print("Current balance is:", self.balance)

# 创建账户
account = BankAccount("John Doe")

# 存款
account.deposit(1000)

# 取款
account.withdraw(500)

# 查询余额
account.check_balance()

可以根据需要进行扩展，例如添加账户列表、转账功能等。
