Bool array to integer

Question

Is there any build in function in python to convert a bool array (which represents bits in a byte) like so:

p = [True, True, True, False, True, False, False, True]

into a byte array like this:

bp = byteArray([233])

I am aware oh numpy but I was looking for something within python itself

Answer 1

This will do what you want:

sum(v<<i for i, v in enumerate(p[::-1]))

Answer 2

Just use algebra:

sum(2**i for i, v in enumerate(reversed(p)) if v)
