Generate Truth Table but leave some variables undefined in python

input:

vv = [True, False, None, True, None]

Is there a way to generate truth table by replacing undefined one boolean at a time So the ouptut would be

[True, False, True, True, None]
[True, False, False, True, None]
[True, False, None, True, False]
[True, False, None, True, True]

Assuming that Undefined can be None, for example, you could do as follows:

l = [True, False, None, True, None]

# first get indices of None/Undefined elements in the input list
indexes = [i for i,v in enumerate(l) if v is None]

# for each index, generate new list using True and False
# as substitutes.
for idx in indexes:
    for sub in [True, False]:
        new_l = l[:]
        new_l[idx] = sub
        print(new_l)

This gives:

[True, False, True, True, None]
[True, False, False, True, None]
[True, False, None, True, True]
[True, False, None, True, False]
