Components of pandas
The two main components of pandas are DataFrame and Series.
A DataFrame represents a two-dimensional table. It consists of a collection of Series.
A Series represents one-dimensional column (actually, a 1D NumPy array).
Therefore, a DataFrame can be seen as a way of representing data in rectangular grids.
Each row in the table represents the values of an instance, and each row has an Index.
The columns are ‘connected’ by the Index
Each column is a vector containing data for a speific variable.
The columns are identified by the column names.
