Yes; while trigrams are evidently of sublime relevance to martial
artists of the Baguazhang (eight-trigrams palm) school (see below), I
guess you are probably more interested in length-3 substrings of a
string, used in indexing and approximate matching ...

I presume that you *don't* mean ANSI C's "trigraph sequences" [bletch]

You will find lots of stuff if you google(trigram python), most of it
more relevant than this extract from

Tian has undertaken to write a book entitled "Yin-Yang Baguazhang."
[...]according to ancient Chinese philosophy underlying the theory of
eight trigrams. The book will be published in eight volumes named
after eight animals in association with their typical movements - the
python crawling through a bush, [...]

Google. Note that trigrams are merely a special case of n-grams (n ==
3) and much of the literature just talks about n-grams or N-grams or
ngrams. You'll need to google with ngram and ngrams and "n-gram" and
"n-grams" separately.

Here's what promises to be a good starting point (found via "n-gram"):

Please in future do web searches *before* you ask questions. Otherwise
people may give no answer, or a short literal logical but sarcastic &
useless answer -- (Q: does anyone here know X and Y or Z? A: Yes)

Hope this helps,
