One of the advantages of Pengines is that it allows seamless access to a Prolog engine from other programming libraries. This can be useful when building large applications where not everyone is familiar with Prolog.

The pengines library on PyPi provides a library for accessing a Pengines service from Python. It can be installed in the usual way:

pip install pengines

Once you have installed this, and have a Pengines service running, you can write code like this:

query = "member(X, [1,2,3])"
pengine.ask(query)
print(pengine.currentQuery.availProofs)

You can combine this with the prologterms package on PyPi to write more prolog-esque Python.
