python - Error while converting binary to integer when the last bit is zero [low] -


i using manual method convert binary decimal. code works fine last bit high eg: 1001. error arises when last bit zero[low]. eg: 1010 should give 10 gives 5 because last bit not considered.could 1 me in this.

x=raw_input('enter binary value:') x=[int(xi) xi in x]  sum=0 in range(0,len(x)):     sum=sum+x[i]*(pow(2,i))  print sum

you're misinterpreting problem. issue isn't it's ignoring last bit if it's 0, problem it's reading binary sequence backwards. when feed in "1010", processes "0101".

sum = sum + x[i] * (pow(2, len(x) - - 1))

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
