<p>要了解村级作物的数量,请使用以下公式:</p>
<pre><code>D.filter(items = ["VillageName","Crop", "Area"],axis=1).groupby(by = ["VillageName","Crop"])
</code></pre>
<p>然后可以除以SUMTOAL of crops Area(D.filter(items=[“crops”,“Area”],axis=1).groupby(by=“cropo”))或SUMTOAL of Village Area(D.filter(items=[“VillageName”,“Area”],axis=1).groupby(by=“VillageName”))得到比例。你知道吗</p>
