[issue21071] struct.Struct.format is bytes, but should be str
by Serhiy Storchaka 18 Dec '14

18 Dec '14

Serhiy Storchaka added the comment: I think breaking the compatibility should be discussed on Python-Dev. Similar issue (and even worse) is issue8934. ---------- nosy: +serhiy.storchaka _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue21071> _______________________________________

[issue21071] struct.Struct.format is bytes, but should be str
by Martin Panter 18 Dec '14

18 Dec '14

Martin Panter added the comment: Here is a patch that changes over to a str() type. Is it safe to assume PyUnicode_AsUTF8() is null-terminated (like PyBytes_AS_STRING() is)? My documentation doesn’t say. ---------- Added file: http://bugs.python.org/file37488/format-str.patch _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue21071> _______________________________________

[issue23073] Broken turtle example in Cmd documentation
by bbc 17 Dec '14

17 Dec '14

New submission from bbc: The documentation page for the cmd module contains an example with the turtle module: https://docs.python.org/3.4/library/cmd.html#cmd-example It seems like the turtle module has changed quite a bit since the code was written, and exposes a Pen class instead of all the various movement functions. The example, while still useful, cannot be executed as is. I like the example and would be happy to provide an idiomatic replacement if you think this is necessary. ---------- assignee: docs@python components: Documentation messages: 232829 nosy: bbc, docs@python priority: normal severity: normal status: open title: Broken turtle example in Cmd documentation type: behavior versions: Python 3.4 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue23073> _______________________________________

[issue21071] struct.Struct.format is bytes, but should be str
by Martin Panter 17 Dec '14

17 Dec '14

Martin Panter added the comment: I originally assumed it would be a text string from the existing documentation, so changing the behaviour to match also seems reasonable ---------- _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue21071> _______________________________________

[issue21071] struct.Struct.format is bytes, but should be str
by STINNER Victor 17 Dec '14

STINNER Victor added the comment: > It would be backwards incompatible to change, though. I'm in favor of breaking the compatibility with Python 3.4 and return the format as an Unicode string. ---------- nosy: +haypo _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue21071> _______________________________________

I am experimenting with Python step by step. The very first step in the Python for Dummies is >>>Print. This gives me an error message. Any command of print gives an error.

[issue23070] Error in Tutorial comment
by Ross Burnett 17 Dec '14

17 Dec '14

New submission from Ross Burnett: In section "3.1.2. Strings" of the Tutorial (version 3.4 plus others?), a comment on a slicing error has an error: "word[42] # the word only has 7 characters" It should say "word[42] # the word has 6 characters" ---------- assignee: docs@python components: Documentation messages: 232795 nosy: docs@python, rossburnett priority: normal severity: normal status: open title: Error in Tutorial comment versions: Python 3.4 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue23070> _______________________________________

[issue23049] Fix functools.reduce code equivalent.
by Terry J. Reedy 17 Dec '14

17 Dec '14

New submission from Terry J. Reedy: from functools import reduce def add(a,b): return a+b reduce(add, {}) >>> Traceback (most recent call last): File "C:\Programs\Python34\tem.py", line 3, in <module> reduce(add, {}) TypeError: reduce() of empty sequence with no initial value However, the reduce-equivalent code in the doc sets a bad example and forgets to account for empty iterators. def reduce(function, iterable, initializer=None): it = iter(iterable) if initializer is None: value = next(it) else: ... So it lets the StopIteration escape (a bad practice that can silently break iterators). The code should be def reduce(function, iterable, initializer=None): it = iter(iterable) if initializer is None: try: value = next(it) except StopIteration: raise TypeError("reduce() of empty sequence with no initial value") from None else: ... (patch coming) ---------- assignee: docs@python components: Documentation, Interpreter Core messages: 232626 nosy: docs@python, terry.reedy priority: normal severity: normal stage: needs patch status: open title: Fix functools.reduce code equivalent. type: behavior versions: Python 3.4, Python 3.5 _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue23049> _______________________________________
