python build a dynamic growing truth table

Question

My question is simple: \"how to build a dynamic growing truth table in python in an elegant way?\"

for n=3

for p in False, True:
    for q in False, Tru         


        

Answer 1

Easy math aproach:

a = lambda x: [x//4%2,x//2%2,x%2]

for i in range(8):
    print(a(i))

[0, 0, 0]
[0, 0, 1]
[0, 1, 0]
[0, 1, 1]
[1, 0, 0]
[1, 0, 1]
[1, 1, 0]
[1, 1, 1]

EDIT:

A more general format wold be:

def truth_table(n):
    for i in range(2**n):
        line = [i//2**j%2 for j in reversed(range(n))]
        print(line)

This will only print the result as:

>>> truth_table(3)
[0, 0, 0]
[0, 0, 1]
[0, 1, 0]
[0, 1, 1]
[1, 0, 0]
[1, 0, 1]
[1, 1, 0]
[1, 1, 1]
