我有一份可能有出口问题的商品清单。我想获得重复项目的列表,以便我可以手动比较它们。当我尝试使用熊猫复制方法时,它只返回第一个副本。有没有办法得到所有的副本,而不只是第一个?
我的数据集的一小部分是这样的:

我的代码现在是这样的:
df_bigdata_duplicates = df_bigdata[df_bigdata.duplicated(cols='ID')]
有两个重复的项目。但是,当我使用上面的代码时,我只得到第一项。在API引用中,我看到了如何获得最后一项,但我想拥有所有这些项,这样我就可以直观地检查它们,看看为什么我得到了差异。因此,在这个示例中,我希望获得所有三个A036条目和11795条目以及任何其他重复条目,而不仅仅是第一个条目。任何帮助都非常感激。
