Hello everybody,<br>
<br>
I'm doing an image processing project. When processing the sampling
rate and quantization rate of the image, I come across a strange
phenomenon.<br>
<img alt="" src="cid:part1.09020001.05020103@gmail.com" height="233"
width="572"><br>
<p>Why doesn't __setitem__ exist before help() function but appear
after it?<br>
It is the same even after I execute the express 'data[x,y] =
value'. It only appears after help() function.<br>
Doesn't the express 'data[x,y] = value' call the method
__setitem__ ?<br>
</p>
<p>Thank you<br>
