selecting some rows from Truth Table

Question

I am using Truths class to generate a truth table : https://github.com/tr3buchet/truths

However I could not enumerate all rows or extract rows with correct evaluation of expression? Is there a way to do that ?

I received this error : AttributeError: 'Truths' object has no attribute 'rows' thanks in advance

I can only get the table printed but I could not change it ?

how can I extracted specific rows from table ?

Answer 1

A Truths object stores almost exclusively the information that is provided during initialization. That is: the base items, the phrases (optional) and the ints (also optional). The only other things are:

• a regex method (which is probably not what you are looking for) and
• a list of base_conditions, which stores the part of the table with the base columns

The latter one can be accessed like this:

t = Truths(['a', 'b', 'c'], ['(a and b)', 'a and b or c'])  # example
t.base_conditions # == [(False, False, False), (False, False, True), ... (True, True, True)]

The rest of the table is generated on the fly when the table is printed.

If you have not done it already, have a look at the code in the git repository.
