Keep in mind that the function is somewhat flexible in what types of inputs it will accept as arguments to thexparameter. You can provide a single number, but you can also provide a NumPy array or any array-like
numpy.sqrt(arr,out=None) Parameters arrinput array outIfoutis given, the result will be stored inout.outshould have the same shape asarr. Return It returns an array of the square root of each element in the input array, even ifoutis given. ...

导入数学模块只会发生一次,并且您可能不会比数学模块快得多。还有一个较旧的stackoverflow问题 哪个在Python中更快:X **。5或Math.sqrt(x)?。尚不清楚哪种方法更快。 也许看看 numpy. 和scipy,不一定是SQRT,但如果你正在做一些沉重的计算,他们可能很方便。智能...

而numpy.square() 方法也返回平方数组,如上图所示。如果out 与arr 的形状不一样,就会引发 ValueError。import numpy as np arr = [1, 3, 5, 7] out_arr = np.zeros(3) arr_sq = np.square(arr, out_arr) print(out_arr) print(arr_sq) 输出:...
