如何从我的数据集中提取数字并组成一个数组？

Question

我想从数组等级中仅提取数字

我无法仅提取尝试查找所有内容，包含内容等的数字。

rank[0]
<td class="blob-num js-line-number" data-line-number="100" id="L100"></td>]
len(rank)
100
>>> import re
>>> [int(s) for s in re.findall(r'\b\d+\b', rank[0])]

---------------------------------------------------------------------------
