5.Create a 10x10 array with random values and find the minimum and maximum values (★☆☆) Z = np.random.random((10,10)) print(Z.max()) print(Z.min()) 这道题并不难,但是我把它记录下来是因为我想做一个max和argmax的区分 假如现在有一个函数 : y = f(t) ...
With multi-dimensional arrays, you can use the colon character in place of a fixed value for an index, which means that the array elements corresponding to all values of that particular index will be returned. 对于多维数组,可以使用冒号字符代替索引的固定值,这意味着将返回与该特定索引的所有值...

NumPy zeros is a built-in function that creates a new array filled withzero values. The numpy.zeros() function is one of the most fundamental array creation routines in NumPy, allowing us to quickly initialize arrays of any shape and size. ...
