PyPropLogic is a Python library for parsing, manipulating, and visualizing propositional logic. It provides a set of tools to build and manipulate propositional formulas, and to perform logical operations on them.
To install the module, clone the repository to your local machine and run the following command in the root directory of the cloned repository:
python setup.py install
Alternatively, you can install the library in development mode by running:
python setup.py develop
Here are some examples of how to use this module:
import pyproplogic as ppl
from pyproplogic.common import P, Q, IMPLICATION
# Creating propositional formulas
R = ppl.atom("R")
formula = P & (Q >> R)
random = ppl.random_formula(5)
# Evaluating propositional formulas
valuation = {P: True, Q: False, R: True}
result = formula.eval(valuation) # True
truth_table = formula.get_truth_table()
tautology = IMPLICATION.is_tautology()
# Simplifying propositional formulas
formula = ((P & True) | False) >> Q
simplified = formula.simplify() # Equivalent to "P"
# Converting propositional formulas to CNF and DNF
cnf = formula.to_cnf()
dnf = formula.to_dnf()
# Visualizing propositional formulas
latex_formula = formula.to_latex()
tikz_parse_tree = formula.to_latex_tikz()PyPropLogic is under the MIT license.
