IndexError: only integers, slices (`:`), ellipsis (`...`), numpy.newaxis (`None`) and integer or boo

max0=max(val[i][0],val[i][1])min0=min(val[i][0],val[i][1])high[min0]=h+xhigh[max0]=h+x

The following error occurred in the above code when brushing the question today:
IndexError: only integers, slices (:), ellipsis (...), numpy.newaxis(None) and integer or boolean arrays are valid indices

The reason is that the index Index cannot be a floating point number, it should be changed to an integer type:

max0=int(max(val[i][0],val[i][1]))min0=int(min(val[i][0],val[i][1]))high[min0]=h+xhigh[max0]=h+x
