[korenron]

Hello ,
I have this list

My List ['0x5b', '0x1ab', '0x282', '0x140', '0x6d7', '0x170']
0x5b<class 'str'>
0x1ab<class 'str'>
0x282<class 'str'>
0x140<class 'str'>
0x6d7<class 'str'>
0x170<class 'str'>

I want\need to maks all values with 0xFF

so the finall list will be

0x5b
0xab
0x82
0x40
0xd7
0x70

there is no way to delete this post , I have found how to do it

while i < 6:
    temp= int(MyList[i], 16)
    temp = temp & int(0xff)
    MyList[i] = hex(temp)
    print(MyList[i])
    i += 1

Thanks,
