Wymień wartości macierzy Python
>>> A = np.array((1,7,3,8,4,9,1))
>>> np.where(A>4,1,A)
array([1, 1, 3, 1, 4, 1, 1])
Horrible Hoopoe
>>> A = np.array((1,7,3,8,4,9,1))
>>> np.where(A>4,1,A)
array([1, 1, 3, 1, 4, 1, 1])>>> import numpy as np
>>> M = np.arange(10)
>>> M
array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
>>> M[(M > 2) & (M < 7)] = -1
>>> M
array([ 0, 1, 2, -1, -1, -1, -1, 7, 8, 9])
