nditer对象有另一个可选参数op_flags,默认情况下,nditer将视待迭代遍历的数组为只读对象(read-only),为了在遍历数组的同时,实现对数组元素值得修改,必须指定op_flags=['readwrite']模式: np.nditer(a, op_flags=['readwrite']) 修改数组值的示例: import numpy as np a = np.arange(0,60,5) a = a.reshape(3,4) print '原始数组是:' print a pri
In the game of DotA, Pudge's meat hook is actually the most horrible thing for most of the heroes. The hook is made up of several consecutive metallic sticks which are of the same length. Now Pudge wants to do some operations on the hook. Let us num
