<p>这样就可以了(使用<a href="https://docs.python.org/3/library/functions.html#min" rel="nofollow noreferrer">^{<cd1>}</a>和<code>key</code>参数):</p>
<pre><code>#Suppose a is the multiarray
>>> min(a, key=lambda x: x[5]) # <- x[5] is the 6th field
[0, 0, 2000, 0.2, 75, 0.2767137, 0.41646746]
>>> min(a, key=lambda x: x[6]) # <- x[6] is the 7th field
[0, 0, 2000, 0.2, 50, 0.31941691, 0.38137865]
</code></pre>
