The return value in this case is a tuple with the array as the first element and a float with the step size as the second.Remove ads Nonscalar Values for Higher-Dimensional ArraysYou can also use nonscalar values for start and stop. This returns a higher-dimensional array:...
a = np.array([1,2,3,4,5]) b = np.array([5,6,7,8,9]) 1. 2.期望的输出: array([1,2,3,4]) 1.答案: a = np.array([1,2,3,4,5]) b = np.array([5,6,7,8,9]) # From 'a' remove all of 'b' np.setdiff1d(a,b) # > array([1, 2, 3, 4]) 1. 2. 3. ...

In this example, start is 1. Therefore, the first element of the obtained array is 1. step is 3, which is why your second value is 1+3, that is 4, while the third value in the array is 4+3, which equals 7.Following this pattern, the next value would be 10 (7+3), but ...
