DataFrame is a tabular data structure in Pandas, which contains a set of ordered columns, each of which can be a different value type (value, string, Boolean, etc.), DataFrame has both row index and column index, and can be regarded as a dictionary made up of Series.
Feature: Series
It is an object similar to a one-dimensional array, consisting of a set of data (various NumPy data types) and a set of related data tags (that is, indexes). Simple Series objects can also be generated from a single set of data.
