将DataFrame转换为字典(Dictionary)可以通过Pandas中的to_dict()方法实现。to_dict()方法可以接受不同的参数,以满足不同的需求。 如果不传递任何参数给to_dict()方法,它将返回一个字典,其中列名作为键,列值作为值。这种转换方式适用于将DataFrame的每一列转换为字典中的一个键值对。 示例代码如下: ...
there are times when you will have data in a basic list or dictionary and want to populate a DataFrame. Pandas offers several options but it may not always be immediately clear on when to use which ones.

Pandas provide a method called pandas.DataFrame.to_dict() method which will allow us to convert a DataFrame into a dictionary but the generated output will have the index values in the form of a key. Sometimes we do not want the index values as the key, in that case, we follow another...
