i attempting create program when run ask boolean expression, variables , create truth table whatever entered. need use class , have far. not sure go here.
from itertools import product class boolean(object): def __init__(self, statement, vars): self.exp = statement self.vars = vars def __call__(self, statement, vars): def main(): expression = raw_input('give expression:') vars = raw_input('give names of variables:') variables = vars.split(' ') b = boolean(expression, variables) if __name__ == "__main__": main()
i have library want! check out github repo or find here on pypi.
the readme describes how works, here's quick example:
from truths import truths print truths(['a', 'b', 'x', 'd'], ['(a , b)', 'a , b or x', 'a , (b or x) or d']) +---+---+---+---+-----------+--------------+---------------------+ | | b | x | d | (a , b) | , b or x | , (b or x) or d | +---+---+---+---+-----------+--------------+---------------------+ | 0 | 0 | 0 | 0 | 0 | 0 | 0 | | 0 | 0 | 0 | 1 | 0 | 0 | 1 | | 0 | 0 | 1 | 0 | 0 | 1 | 0 | | 0 | 0 | 1 | 1 | 0 | 1 | 1 | | 0 | 1 | 0 | 0 | 0 | 0 | 0 | | 0 | 1 | 0 | 1 | 0 | 0 | 1 | | 0 | 1 | 1 | 0 | 0 | 1 | 0 | | 0 | 1 | 1 | 1 | 0 | 1 | 1 | | 1 | 0 | 0 | 0 | 0 | 0 | 0 | | 1 | 0 | 0 | 1 | 0 | 0 | 1 | | 1 | 0 | 1 | 0 | 0 | 1 | 1 | | 1 | 0 | 1 | 1 | 0 | 1 | 1 | | 1 | 1 | 0 | 0 | 1 | 1 | 1 | | 1 | 1 | 0 | 1 | 1 | 1 | 1 | | 1 | 1 | 1 | 0 | 1 | 1 | 1 | | 1 | 1 | 1 | 1 | 1 | 1 | 1 | +---+---+---+---+-----------+--------------+---------------------+ hope helps!
