My previous abandonned attempt was the issue #17742. "Add _PyBytesWriter API to optimize Unicode encoders" Oh, I forgot to mention and it may also be used to optimize bytes % args. More generally, any code generating a bytes object with an unknown length is advance. Said differently: _PyBytesWriter can be used when precomputing the output length is more expensive. str % args now uses _PyUnicodeWriter but building an Unicode string is even more complex because of the different Unicode "kinds": 1, 2 or 4 bytes per character. |
