Python在带有numpy数组数据的for循环中添加列表

# For loop to get correlation data of selected (x,y) pixel for all bands
zdata = []
for n in d.bands:
    cor_xy = np.array(d.bands[n])
    zdata.append(cor_xy[y,x])

每次运行程序时,都会出现以下错误：

Traceback (most recent call last):
    File "/home/sdelgadi/scr/plot_pixel_data.py", line 36, in <module>
        cor_xy = np.array(d.bands[n])
TypeError: only integer arrays with one element can be converted to an index

当我在不使用循环的情况下从python解释器尝试时,我的方法有效.

>>> zdata = []
>>> a = np.array(d.bands[0])     
>>> zdata.append(a[y,x])
>>> a = np.array(d.bands[1])
>>> zdata.append(a[y,x])
>>> print(zdata)
[0.59056658, 0.58640128]

创建for循环并手动执行此操作有何不同？如何使我的循环停止导致错误？

zdata = []
for n in d.bands:
    cor_xy = np.array(n)
    zdata.append(cor_xy[y,x])

您说a = np.array(d.bands [0])有效.前n个应该与d.bands [0]完全相同.如果是这样,那么您只需要np.array(n).
