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
