将多维数组的列格式化为一维数组
Formatting columns of multidimensional arrays into 1D arrays
我想访问二维数组的右侧。我想将第二列变成一维数组 4883,4967,4968... 。我试过 list_[len(list_),1] 但这不起作用。我该怎么做。
list_ = np.array([[ 1 4883]
[ 0 4967]
[ 1 4968]
[ 0 4969]
[ 1 4969]
[ 0 4970]
[ 1 4971]
[ 0 4971]
[ 1 4972]
[ 0 4973]
[ 1 4973]
[ 0 4974]
[ 1 4975]
[ 0 4975]
[ 1 4976]])
简单索引如下-
l[:,1]
