To demonstrate, we need some data to work with, but we do not want anything too large and complicated; that is why we have done something we do very frequently. When we are learning something about NumPy, the first thing that comes up is called arrays, so in this case, we already cre...

’ll learn all about np stack — or the Numpy’sstack()function. Put simply, it allows you to join arrays row-wise (default) or column-wise, depending on the parameter values you specify. We'll go over the fundamentals and the function signature, and then jump into examples in Pytho...
This tutorial will introduce how to shuffle two NumPy arrays in Python.NumPy Shuffle Two Arrays With the sklearn.utils.shuffle() Function in PythonSuppose we have two arrays of the same length or same leading dimensions, and we want to shuffle them both in a way that the corresponding ...
NumPy library has many functions to create the array in python. where() function is one of them. Some operations can be done at the time of array creation based on the condition by using this function. How to use python NumPy where() function with multip

Notice that there are two input arguments to the function, which I’ve namedarr1andarr1. These should be Numpy arrays or array-like objects such as Python lists. Also, there are some restrictions on theshapeof the input array. One way to use np.multiply, is to have the two input arra...
