Most Frequently asked dataframe Interview Questions (2024)

A DataFrame is a two-dimensional, size-mutable, and potentially heterogeneous tabular data structure in pandas, which is a widely used data analysis and manipulation library in Python. It is similar to a table in a database or an Excel spreadsheet, where data is organized in rows and columns.
