how do you define pandas dataframe?

A dataframe is a 2D mutable and tabular structure for representing data labelled with axes - rows and columns.

The syntax for creating dataframe:

 

import pandas as pd

dataframe = pd.DataFrame( data, index, columns, dtype)

where:

 

data - Represents various forms like series, map, ndarray, lists, dict etc.

index - Optional argument that represents an index to row labels.

columns - Optional argument for column labels.

dtype - the data type of each column. Again optional.
