python单处理器甘特图

以下是一个使用Python编写的单处理器甘特图的示例代码：

        self.name = name
        self.start = start
        self.end = end

    for i, task in enumerate(tasks):
        row = [' '] * (len(tasks) * 2 + 1)
        row[i * 2 + 1] = task.name

gantt_chart(tasks)

该代码使用Python的datetime模块来处理日期，使用Task类来表示每个任务的名称、开始日期和结束日期。gantt_chart函数接受一个任务列表作为参数，并生成一个甘特图。甘特图是一个二维列表，其中每个元素表示一个日期和任务的组合。在甘特图中，任务用█字符表示，任务的开始和结束日期用┌、┐、└和┘字符表示，任务的持续时间用─字符表示，任务之间的间隔用空格字符表示。
