<p>要替换值:</p>
<pre><code>old_list = [[3, 2, 2, 2, 2, 2, 2, 2], [3, 3, 3, 2, 2, 2, 2], [3, 3, 3, 3, 3, 2], [5, 2, 2, 2, 2, 2, 2], [5, 3, 3, 2, 2, 2], [5, 3, 3, 3, 3], [5, 5, 3, 2, 2], [5, 5, 5, 2]]
dictionary = {2: 70, 3: 85, 5: 120}
new_list = []
temp = []
for i in old_list:
temp = []
for b in i:
temp.append(dictionary[b])
new_list.append(temp)
</code></pre>
<p>输出:</p>
<pre><code>[[85, 70, 70, 70, 70, 70, 70, 70], [85, 85, 85, 70, 70, 70, 70], [85, 85, 85, 85, 85, 70], [120, 70, 70, 70, 70, 70, 70], [120, 85, 85, 70, 70, 70], [120, 85, 85, 85, 85], [120, 120, 85, 70, 70], [120, 120, 120, 70]]
</code></pre>
