The video tutorial covers three main Numpy functions: arrange, reshape, and random. The arrange function is used to generate arrays with specified start, end, and step values. The reshape function converts lists into matrices, allowing for matrix operations. The random function generates random numbers from various distributions, useful in machine learning. The tutorial emphasizes the practical applications of these functions in data manipulation and analysis.
