NumPy arrays are used to store lists of numerical data, vectors and matrices. The NumPy library has a large set of routines (built-in functions) for creating, manipulating, and transforming NumPy arrays. Python language also has an array data structure, but it is not as versatile, efficient and useful as the NumPy array. The NumPy . Contiguous ...

The central feature of NumPy is the array object class. Arrays are similar to lists in Python, except that every element of an array must be of the same type, typically a numeric type like float or int . Arrays make operations with large amounts of numeric data very fast and are generally much more efficient than lists.

NumPy NumPy Arrays From "Anything" to a NumPy Array Given an object a, a = asarray(a) converts a to a NumPy array (if possible/necessary) Arrays can be ordered as in C (default) or Fortran: a = asarray(a, order=’Fortran’) isfortran(a) # returns True of a’s order is Fortran Use asarray to, e.g., allow exible arguments in functions:

Arrays (Numpy) Numpy array is like a list with multidimensional support and more functions. We will be using it a lot. Arithmetic operations on numpy arrays correspond to elementwise operations. Important functions:.shape returns the dimensions of the array.ndim returns the number of dimensions..size returns the number of entries in the array
