Creating NumPy arrays (ndarrays) NumPy arrays are multi-dimensional arrays, they can store homogenous or heterogeneous data. There are different ways we can create a NumPy array. Method 1: Usingarange()method: It will create a range of values as per the given parameter, starting from zero. ...
Let us also compare the time it takes for the two methods to shuffle the same array. We will run the two methods on the same array and log the time it takes for them to shuffle it. We will log times for arrays of lengths ranging from 102to 109, with increments of orders of 10. ...
