Convert list of integers to bit-mapped byte

[wavic]

Hello!
Here is how to set the n-th bit to 1

def set_bit(num, bit_pos):
    if bit_pos == 1:
        return num | 1
    else:
        return num | ( 1<<(bit_pos - 1))

selenoids = 0
for n in [1,3,4,7]:
    selenoids = set_bit(selenoids, n)

To unset the n-th bit just copy the same function, change the name to unset_bit and replace '|' with '&'. The first one is bitwise OR and the second is AND.
