You should check for when the input value is out of the positive range for 32 bit signed integers: res = int (block, 2) if res >= 2**31: res -= 2**32. So first you interpret the number as an unsigned number, but when you notice the sign bit was set ( >= 2^31 ), you subtract 2^32 so to get the negative number. Share. rds steam
