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. WebDec 29, 2024 · The set of all bit strings of length n can be found by counting (the f-string is just formatting it to make it binary and pad with zeroes), which range does quite handily. – ShadowRanger Dec 29, 2024 at 20:42 Add a comment 0 Using a recursive generator could make the code much more compact.
