Q. What is a DataFrame and how is it different from a 2-D array?

Answer :-

A DataFrame is a two-dimensional labelled data structure like a table of MySQL. It contains rows and columns, and therefore has both a row and column index.
a 2-dimensional array: you have rows and columns. The rows are indicated as the “axis 0”, while the columns are the “axis 1”.
