Let’s walk through an example of howall()can be used in Python. Say that we have a list of Boolean values which store whether or not John Appleseed has ranked in the top 10 in any Indy 500 race. If we want to find out whether he has ranked in the top 10 in all of his races...
We will use np.where() for this purpose and pass our specific condition to create a mask of values.Let us understand with the help of an example,Python program to turn a boolean array into index array in numpy# Import numpy import numpy as np # Creating a numpy array arr = np.arange...
