Array

In Data Science, an array is a collection of similar data types stored in contiguous memory locations. It is a fundamental data structure used to store and manipulate large amounts of data efficiently. Arrays can be one-dimensional, two-dimensional, or multi-dimensional, depending on the number of indices required to access the elements. One-dimensional arrays are commonly used to store lists of data, while two-dimensional arrays are used to store tables of data. Multi-dimensional arrays are used to store data with more than two dimensions, such as images or videos. Arrays can be created and manipulated using various programming languages and libraries, such as NumPy in Python. They are essential for many data science tasks, such as data preprocessing, feature engineering, and model training.
