WebReading and parsing. The BitStream and ConstBitStream classes contain number of methods for reading the bitstring as if it were a file or stream. Depending on how it was constructed the bitstream might actually be contained in a file rather than stored in memory, but these methods work for either case. In order to behave like a file or stream ... WebThe term ‘bitstring’ is used in this manual to refer generically to any of these classes. Most of the examples in this manual use the BitArray class, with BitStream used when necessary. For most uses the non-const classes are more versatile and so probably your best choice when starting to use the module.

You can convert them to integers with int specifying the base to be 2. Then, perform a bitwise OR operation and convert the result to a bit string with bin. >>> c = int (a, 2) int (b, 2)) >>> c 23. If you want to print the result as a bit string, use str.format. If you're on python-3.6, you can also use f-strings.
