pyton 股票卖出买出

在Python中，模拟股票买卖通常涉及到金融市场的数据处理和交易策略的实现。以下是一个简单的例子，展示如何使用基本的买入和卖出操作：

class Stock:
    def __init__(self, name, price):
        self.name = name
        self.price = price

    # 模拟买入函数，假设资金充足
    def buy(self, shares, cost):
        if self.enough_funds(cost * shares):  # 检查是否有足够的资金
            self.shares += shares
            self.cash -= cost * shares  # 减少现金
            return True
        else:
            print(f"Insufficient funds for {shares} shares of {self.name}")
            return False

    # 模拟卖出函数，假设有足够股票
    def sell(self, shares):
        if self.has_enough_shares(shares):  # 检查是否有足够的股票
            self.shares -= shares
            self.cash += self.price * shares  # 增加现金
            return True
        else:
            print(f"Not enough shares to sell {shares} of {self.name}")
            return False

    # 内部辅助函数检查资金和股份数量
    def enough_funds(self, cost):
        return self.cash >= cost

    def has_enough_shares(self, shares):
        return self.shares >= shares

# 使用示例
stock = Stock("Apple", 150)
stock.cash = 10000  # 假设初始现金为10000元
# 买入100股苹果
if stock.buy(100, 150):
    print(f"Bought {stock.shares} shares of {stock.name}")

# 卖出部分股票，假设价格变为160
if stock.sell(50):  # 卖出50股
    print(f"Sold {stock.shares} shares of {stock.name}, now worth {stock.price * stock.shares}")
