I am trying to determine how to test whether variors bits are set within
a byte (or larger flag) , the python 'and' and 'or' do not seem to be
doing what i want .. does anybody have some sample code showing how to
do it ??
e.g. (in "C")
unsigned char a = 6;
is 3rd bit set ??
a & 4 =, true in this case ....
'and', 'or' and 'not' are Boolean.
Python borrows its bitwise operators from C:
& bitwise and
| bitwise or
^ bitwise xor
~ bitwise not (ones' complement)
<< shift left
>> shift right
You also need to remember that Python's integers are of (virtually)
unlimited length.
