Utilize Python bit operators

study libraryA

    while i != 0:
        result.append(i & 0xFF)
        i >>= 8

I found this part.

In Python, >> is a bit operator that shifts to the right.

But the bit operator I know is

100 >> 2 = Shift 2 spaces to the right

100 <<4 = shift by 4 spaces to the left

I understand that you are using it, but I don't know what the code is for.

SyntaxError occurs if you just enter the command.

3234234 >>=8
>>> SyntaxError: can't assign to literal

I copied the library exactly the same and printed it out.

i = 1241535

while i!=0:
     result.append(i&0xFF)
     print(i)
     i>>=8
     print(i)
     print('-------------')
1241535
4849
-----------
4849
18
----------
18
0
---------

I think it's causing a shift if you look at the decreasing number

I wonder exactly what that >>= does.

If you have any explanations or related materials, please advise.

Thank you.
