  What are the differences between NumPy arrays and Pandas DataFrames? When would you use each? When working with data in Python, two of the most commonly used libraries are  NumPy  and  Pandas . While they serve overlapping purposes, they are designed for different use cases. Understanding the differences between  NumPy arrays  and  Pandas DataFrames  can help you decide which one to use depending on your project requirements. 1. Structure and Data Representation NumPy Arrays : NumPy arrays are n-dimensional arrays (ndarrays) designed for numerical computations. They store homogeneous data types, meaning all elements in the array must be of the same type (e.g., all integers or all floats). Example : import numpy as np # Creating a NumPy array arr = np.array([1, 2, 3, 4]) print(arr) Pandas DataFrames : Pandas DataFrames are 2-dimensional labeled data structures, similar to tables in a relational database or Excel. They can store heterogeneous data...
