[issue46375] io.BytesIO does not have peek()
New submission from Marcel Martin : It would be great to be able to use peek() on BytesIO objects. I have a function that gets passed a file-like object and uses peek() on it. This works for nearly all types of files relevant in my library, except BytesIO instances (which I use during testing), for which I need to add a small workaround using tell() and seek(). -- components: Library (Lib) messages: 410552 nosy: marcelm priority: normal severity: normal status: open title: io.BytesIO does not have peek() type: enhancement versions: Python 3.11 ___ Python tracker <https://bugs.python.org/issue46375> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue46375] io.BytesIO does not have peek()
Marcel Martin added the comment: I opened a PR, but I now wonder whether the missing peek() is by design. First, I noticed that instead of using BytesIO directly, I can wrap the instance in an io.BufferedReader, which does have peek(). (It’s just a bit inconvenient.) The second thing is that BytesIO is currently documented to inherit from BufferedIOBase, but if peek() is implemented, one could argue that BytesIO now should inherit from BufferedReader because it then has all the methods. And that seems to great a change from my perspective. I’ll defer to someone more knowledgeable and do not mind at all if this issue is closed without action. -- ___ Python tracker <https://bugs.python.org/issue46375> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
