Python 熊猫数据帧

我想使用pandas dataframe、列名-产品标题和填充t来表示数据

例如：

产品名称

惊奇漫画：电影收藏

惊奇

晚餐电影等等

我尝试添加函数并加入，但它无法工作。。我们在熊猫数据帧中有任何特定的功能吗

所需的输出应该是使用数据帧的结果

这将让您开始，它将所有标题提取到一个dict中（为了方便起见，我使用defaultdict）：

---

因此，您可以修改此脚本，将价格和参与者添加为数据dict的键，然后根据结果dict构造df，这比一次追加一行要好

您可以发布原始输入数据和所需输出吗，您的问题是，我不清楚这应该是什么样子，为了回答您的问题，添加数据当然存在，但根据您想要实现的目标，可能有更好的方法更快、更高效地创建df。我已经在沃尔玛查询结果网站上留下了疤痕。看起来您只需要一个带有单栏“产品标题”的df，而在本栏中只需要一个电影列表正确，或者你也想要价格和演员？这是我代码片段的一部分。。所以现在只有产品标题作为一个单独的栏目出现在电影列表中。太棒了……它给了我想要的输出。我将再次浏览文档并在其中添加列。感谢你的努力。非常感谢。
