Print all possible conditions in Python

Question

There are four sensors they're whether on (0) or off (1).

They all can be on or off at the same time.

Example conditions are as below:

A0 0
A1 0
A2 1
A3 0

Another one:

A0 1
A1 1
A2 1
A3 1

How can I print all possible conditions?

I'm writing a code that requires to check which condition is true to do something, and by the time I have wrote ten conditions by thinking. But I think another code can help me to have all conditions.

Use itertools.product. Example:

>>> import itertools
>>> for p in itertools.product((0, 1), repeat=4):
...     for i, v in enumerate(p):
...         print(f"A{i} {v}")
...     print("----")
...

Use itertools.product

>>> list(itertools.product([0, 1], repeat=4))

[(0, 0, 0, 0),
 (0, 0, 0, 1),
 (0, 0, 1, 0),
 (0, 0, 1, 1),
 (0, 1, 0, 0),
 (0, 1, 0, 1),
 (0, 1, 1, 0),
 (0, 1, 1, 1),
 (1, 0, 0, 0),
 (1, 0, 0, 1),
 (1, 0, 1, 0),
 (1, 0, 1, 1),
 (1, 1, 0, 0),
 (1, 1, 0, 1),
 (1, 1, 1, 0),
 (1, 1, 1, 1)]
