Get length of binary number python
WebAug 1, 2024 · You can use the bit_length method on an integer object to check how many bits are necessary to hold the number in binary notation. For example the number 3 in binary notation is 11, so it takes up 2 bits. We can use the method on literals if they are enclosed in parentheses: >>> (3).bit_length () 2. WebJul 20, 2024 · To get bits 4-6 (from left) in a byte: >> msg = int ("10110111", 2) # or 0b10110111 >> extractor = int ("00011100", 2) # or 0b10110111 >> result = msg & extractor >> print bin (result) 00010100 If you want, you can bit shift result using result >> 2. Obviously you will want to make this more dynamic but this is a dumbed down example. …
