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. Each column can hold different data types (e.g., integers, floats, strings), making it more flexible and powerful than a regular 2D array.
