Data Frames
In data science, a data frame is a two-dimensional labeled data structure with columns of potentially different types. It is similar to a spreadsheet or a SQL table, or a dictionary of Series objects. It is the most commonly used data structure in data analysis and machine learning. Data frames can handle both structured and unstructured data, and can be used for data cleaning, data transformation, data visualization, and statistical analysis. They are widely used in programming languages such as R, Python, and Julia, and are supported by many data analysis libraries and tools.
