Concatenation

Concatenation is the process of combining two or more strings, arrays, or data sets into a single entity. In data science, concatenation is often used to merge data sets with similar attributes or to combine data sets with different attributes to create a more comprehensive data set. Concatenation can be performed horizontally, where data sets are merged by adding columns, or vertically, where data sets are merged by adding rows. This process is commonly used in data preprocessing, where data sets are cleaned, transformed, and prepared for analysis. Concatenation is also used in machine learning, where data sets are combined to create a larger training set or to create a more diverse set of features for a model to learn from.
