我应如何更改矩阵的值，以将其四舍五入为％0f格式？

最佳答案

您可以使用numpy's vectorize函数并传递要应用于列表的函数：

import numpy as np
rfunc = np.vectorize(round)     # round() is a python function which rounds inputs to a precision set by number of decimals; e.g: np.round(2.3456, 1) returns 2.3
rfunc(a, 2)     # 2 is the precision which needs to be adjusted
