A library and command-line tool for working with Boolean expressions

Project description

tt's PyPI page Linux build on Travis CI Windows build on AppVeyor

Synopsis

tt is a Python library and command-line tool for working with Boolean expressions. Please check out the project site for more information.

Installation

tt is tested on CPython 2.7, 3.3, 3.4, 3.5, and 3.6. You can get the latest release from PyPI with:

pip install ttable

Basic Usage

tt aims to provide a Pythonic interface for working with Boolean expressions. Here are some simple examples from the REPL:

>>> from tt import BooleanExpression, TruthTable
>>> b = BooleanExpression('A xor (B and 1)')
>>> b.tokens
['A', 'xor', '(', 'B', 'and', '1', ')']
>>> b.symbols
['A', 'B']
>>> print(b.tree)
xor
`----A
`----and
     `----B
     `----1
>>> b.evaluate(A=True, B=False)
True
>>> t = TruthTable(b)
>>> print(t)
+---+---+---+
| A | B |   |
+---+---+---+
| 0 | 0 | 0 |
+---+---+---+
| 0 | 1 | 1 |
+---+---+---+
| 1 | 0 | 1 |
+---+---+---+
| 1 | 1 | 0 |
+---+---+---+
>>> t = TruthTable(from_values='01xx')
>>> t.ordering
['A', 'B']
>>> for inputs, result in t:
...     inputs, result
...
(<BooleanValues [A=0, B=0]>, False)
(<BooleanValues [A=0, B=1]>, True)
(<BooleanValues [A=1, B=0]>, 'x')
(<BooleanValues [A=1, B=1]>, 'x')
>>> t.equivalent_to(b)
True
