Next, let’s also define some example data in Python:my_array = np.array([[1, 2, 3], [4, 5, 6]]) # Create example array print(my_array) # Print example array # [[1 2 3] # [4 5 6]]As you can see based on the previously shown output of the Python console, our ...
xarr = np.array([1.1, 1.2, 1.3, 1.4, 1.5]) yarr = np.array([2.1, 2.2, 2.3, 2.4, 2.5]) cond = np.array([True, False, True, True, False]) result = np.where(cond, xarr, yarr) result 输出:array([1.1, 2.2, 1.3, 1.4, 2.5]) arr = randn(4, 4) arr 输出:array([[-1.0795...
