Python 2 has reached end of life on January 1st, 2020 as documented here. So, PySwip 0.2.10 will be the last version which officially supports Python 2.
Do you still require Python 2 support? Let us know at: yuce#94
See the CHANGELOG.
This library is being cleaned up and refactored. Expect API breakage and incompatibility with previous versions.
WARNING! PySwip has no Windows installers! If you are a Windows user, see INSTALL. There are some "free download" sites that claim to be hosting PySwip installers. DO NOT TRUST THEM!
Thanks to all contributors.
PySwip is a Python - SWI-Prolog bridge enabling to query SWI-Prolog in your Python programs. It features an (incomplete) SWI-Prolog foreign language interface, a utility class that makes it easy querying with Prolog and also a Pythonic interface.
Since PySwip uses SWI-Prolog as a shared library and ctypes to access it, it doesn't require compilation to be installed.
- Python 2.7 or 3.4 and higher.
- PyPy is currently not supported.
- SWI-Prolog 7.2.x and higher.
libswiplas a shared library. This is the default on most platforms.- Works on Linux, Windows, MacOS and FreeBSD. Should work on other POSIX.
IMPORTANT: Make sure the SWI-Prolog architecture is the same as the Python architecture. If you are using a 64bit build of Python, use a 64bit build of SWI-Prolog, etc.
See INSTALL for instructions.
from pyswip import Prolog
prolog = Prolog()
prolog.assertz("father(michael,john)")
prolog.assertz("father(michael,gina)")
list(prolog.query("father(michael,X)")) == [{'X': 'john'}, {'X': 'gina'}]
for soln in prolog.query("father(X,Y)"):
print(soln["X"], "is the father of", soln["Y"])
# michael is the father of john
# michael is the father of ginaAn existing knowledge base stored in a Prolog file can also be consulted, and queried. Assuming the filename "knowledge_base.pl" and the Python is being run in the same working directory, it is consulted like so:
>>> from pyswip import Prolog
>>> prolog = Prolog()
>>> prolog.consult("knowledge_base.pl")
from __future__ import print_function
from pyswip import Prolog, registerForeign
def hello(t):
print("Hello,", t)
hello.arity = 1
registerForeign(hello)
prolog = Prolog()
prolog.assertz("father(michael,john)")
prolog.assertz("father(michael,gina)")
print(list(prolog.query("father(michael,X), hello(X)")))from __future__ import print_function
from pyswip import Functor, Variable, Query, call
assertz = Functor("assertz", 1)
father = Functor("father", 2)
call(assertz(father("michael","john")))
call(assertz(father("michael","gina")))
X = Variable()
q = Query(father("michael",X))
while q.nextSolution():
print("Hello,", X.value)
q.closeQuery()
# Outputs:
# Hello, john
# Hello, ginaThe core functionality of Prolog.query is based on Nathan Denny's public domain prolog.py.
