enter string into list according to a known rule

[korenron]

yes this is what I want
because Bytes are numbers from 1-8
and in the list it's 0-7

I understand what you said about the str and list
my item was a list on 1 item ....
this was my mistake
now everything works as it should be :-)
Thank you !

another question for this code:

sometime I need to analyze only some bits from the byte (not the all byte)
I know how to converte the answer to bits using

Test_bits = "{0:b}".format(Test)

so if I have:
0xF0 it's 240 Dec --> 11110000 bits

if I want to take bits 4 and 5 (which is 1 0 )
now I split the data using

wanted_bits = Test_bits[3:5]

beacsue the string is left to right , but the bits order are right to left
what would be the easy way to make the cut according to the bits order and not the string order ?

this is what I'm doing now

def GetBits(Byte, start, end):
    bits = "{0:b}".format(Byte)
    Full_bits = bits.zfill(8)
    Wanted_bits = Full_bits[start:end]
    return Wanted_bits

**the reason is to avoid confusion while writing the code

Thanks,
