best way to align words?

[Robert R.]

Hello,

thanks for all your replies, i'm now looking to dynamic programming...

sorry for forgetting to say that i wanted the words to be ordered, thus
:

s1 = "hello there dudes"
s2 = "dudes hello there"
s3 = "there dudes hello"

will not return anything while sharing all three words.

Bearophile your solution with graph looks interesting although i still
do not understand how it works, but yes there is definitively something
with drawing path around words.

i have tried SequenceMatcher from difflib after using combinations of
all sentences as i need to process much more than the 3 of my first
example.

best.
