Longest common substring from more than two strings - Python
<p>I'm looking for a python library for finding the longest common substring from a set of python strings.</p>

<p>I'have read that it exist to way to solve this problem :
- one using suffix trees
- the other using dynamic programming.</p>

<p>The method implemented is not important. Otherwise, it is important to have a implementation that can be use for a set of strings and not only two strings</p>

<p>Thanks,</p>
