NumPy library is used in python to create one or more dimensional arrays. The unique() function is one of this library's useful functions to find out the unique values of an array and return the sorted unique values. How to use the python NumPy unique()
zeros() and ones() are the NumPy library functions to create two different arrays. zeros() function is used to create an array based on the particular shape and type. All array elements are initialized to 0, which is created by the zeros() function. ones

NumPy argsort() function in Python is used to calculate an indirect sort along the specified axis using the algorithm specified by the kind keyword. It
As with any programming library, NumPy needs to be added only to an existing Python installation, and programmers can easily write Python code that makes calls and exchanges data with NumPy features and functions. The NumPy library was first released in 2006. Today, the scientific computing commun...
