Converting a numerical array to an integer array using “numpy.astype(int)” import numpy as np a = np.array([1.1, 2.2, 3.3, 4.4, 5.5, 6.6]) b = a.astype(int) print(b) Output:[1 2 3 4 5 6] These are the main functions for changing the type of arrays in NumPy. The choice...
Solution: To union a list of sets, use the following strategy: Create a new set using the set() constructor. Call the union() method on the new set object. Pass all sets as arguments into the union() method by unpacking the list with the asterisk operator *list. The result of the ...
