Explore the NumPy ndarray object, its dtype-based elements, and how to create multi-dimensional arrays with shape and memory order (row-major or column-major).
Learn to create numpy arrays from existing data by converting lists, tuples, buffers, and Python objects using dtype control, and one-dimensional array generation.
Explore how to iterate over NumPy arrays with for loops, reshape and transpose arrays, and control memory order (C-order, F-order) to influence element access and broadcasting.
Learn NumPy arithmetic on arrays with broadcasting, including addition, subtraction, multiplication, and division. Explore reciprocal, power, remainder, and complex-number operations, including real and imaginary parts, conjugate, and angle in degrees.
Learn to call NumPy's sort and search functions, control sorting with axis and kind parameters, and reconstruct sorted data using indices, including sorting records by name or age.
Understand copies and views in numpy, assignment aliases memory without copying, slicing creates a view, and copy and deep copy yield independent data.
The data analytics needs specialized data structure for storing numerical data. The numpy library provides the required data stucture. NumPy is a Python package. It stands for 'Numerical Python'. It is a library consisting of multidimensional array objects and a collection of routines for processing of array. In this course python numpy library is explained in details. In this tutorial you will learn,
