Pandas:

Pandas is seriously a game changer when it comes to cleaning, transforming, manipulating and analyzing data.

Series:

Pandas Series is a one-dimensional labeled array capable of holding data of any type (integer, string, float, python objects, etc.). The axis labels are collectively called index

Pandas Series is nothing but a column in an excel sheet. Labels need not be unique but must be a hashable type. 




DataFrames:

DataFrame is a 2-dimensional labeled data structure with columns of potentially different types. You can think of it like a spreadsheet or SQL table, or a dictionary of Series objects. It is generally the most commonly used pandas object.
