The difference between Series and Dataframe is, in series the data is in the forma of Key-value pair. In the case of DataFrame it is multple-rows and mulriple-columns. Here is Python ‘PDB’ Tutorial to Debug at Command-Line.
1. Series Data
Series data is Key, Value pair. Below is the best example for Series data.
Here the Key is index. Below is the example how Key value pair appears.
The dataFrame is an ordered collection of data. You can create data in multiple dimensions.
The Data in the tabular form. It consists of Data, Rows, Columns. Example DataFrame from geeksforgeeks.com
In Python, to work with DataFrame, you need Pandas installed.
