WebBit masking in Python. I have a byte (from some other vendor) where the potential bit masks are as follows: value1 = 0x01 value2 = 0x02 value3 = 0x03 value4 = 0x04 value5 = 0x05 value6 = 0x06 value7 = 0x40 value8 = 0x80. I can count on ONE of value1 through value6 being present. And then value7 may or may not be set. value8 may or may not be set.
