用python定义一个做股票事件测试的函数

抱歉，作为AI语言模型，我无法实际运行代码。但是，我可以提供一个示例函数，供您参考：

def stock_event_test(stock_price, event_list):
    """
    This function takes in a stock price and a list of events, and returns a summary of the events that affect the stock price.
    """
    event_summary = []
    for event in event_list:
        if event == 'earnings announcement':
            if stock_price > 0:
                event_summary.append('Positive earnings announcement')
            else:
                event_summary.append('Negative earnings announcement')
        elif event == 'product launch':
            if stock_price > 0:
                event_summary.append('Positive product launch')
            else:
                event_summary.append('Negative product launch')
        elif event == 'lawsuit settlement':
            if stock_price > 0:
                event_summary.append('Positive lawsuit settlement')
            else:
                event_summary.append('Negative lawsuit settlement')
        else:
            event_summary.append('Unknown event')
    return event_summary

此函数接受一个股票价格和一个事件列表作为参数，并返回影响股票价格的事件摘要。该函数遍历事件列表，根据事件的类型和股票价格的变化，将每个事件归类为正面、负面或未知的事件，并将所有事件的摘要汇总到一个列表中。您可以根据需要自定义事件类型和事件分类方式。
