arr = np.array([10, 15, 20, 25, 30, 35, 40]) print(arr[1 : 4 : 2])

arr = np.array([10, 15, 20, 25, 30, 35, 40]) print(arr[1 :4 :2])

arr = np.array([10, 15, 20, 25, 30, 35, 40]) print(arr[1:5:2])

arr = np.array([10, 15, 20, 25, 30, 35, 40]) print(arr[1: 5: 2])

arr = np.array([10, 15, 20, 25, 30, 35, 40]) print(arr[1 : 5 : 2])

arr = np.array([10, 15, 20, 25, 30, 35, 40]) print(arr[1 :5 :2])
