I have a library that does exactly what you want! Check out the github repo or find it here on pypi.

The readme describes how everything works, but here's a quick example:

from truths import Truths
print Truths(['a', 'b', 'x', 'd'], ['(a and b)', 'a and b or x', 'a and (b or x) or d'])
+---+---+---+---+-----------+--------------+---------------------+
| a | b | x | d | (a and b) | a and b or x | a and (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 this helps!
