Question
40.Which among the given is true for the statement:- A DataFrame in Pandas is a: A. 2-dimensional array B. Multidimensional array C. 1-dimensional array D. 3-dimensional array
Solution
The correct answer is A. A DataFrame in Pandas is a 2-dimensional array.
Here's why:
Pandas DataFrame is a two-dimensional size-mutable, potentially heterogeneous tabular data structure with labeled axes (rows and columns). It is generally the most commonly used pandas object. It is similar to a spreadsheet or SQL table, or a dictionary of Series objects.
So, it's not a multidimensional array (B), not a 1-dimensional array (C), and not a 3-dimensional array (D). It's a 2-dimensional array (A).
