[英]How to convert all numbers in a 2d numpy array to strings?
I have a 2d numpy array of ints called M. I would like to convert all the ints to strings returning a 2d numpy array of the same shape.我有一个名为 M 的 2d numpy 整数数组。我想将所有整数转换为返回相同形状的 2d numpy 数组的字符串。 How can you do that?
你怎么能那样做?
I tried map(str, M)
but that doesn't work as it converts the individual rows into strings.我尝试了
map(str, M)
但这不起作用,因为它将各个行转换为字符串。
If I have understood it right, you are trying to convert all integer elements in the array to a string.如果我理解正确,您正在尝试将数组中的所有 integer 元素转换为字符串。 To do so, this should work:
为此,这应该有效:
np.char.mod('%d',M)
