Problem with Python Idle
by Peter McCahy 30 Dec '14

30 Dec '14

Good afternoon, I hope you can assist. I have decided to learn some programming and have downloaded Python as it appears to offer the advantage of being logical without being over complicated. I have installed Python 3.4 on my Mac which is running OS X 10.10.1 Yosemite. When I open the program Idle I get the message >>> WARNING: The version of Tcl/Tk (8.5.9) in use may be unstable. Visit http://www.python.org/download/mac/tcltk/ for current information. I tried typing in some lines of code copied from a Python tutorial I found on the Python website After Hours Programming Python 3 Tutorial <http://www.afterhoursprogramming.com/tutorial/Python/Overview/> (Python 3) Although the code ran OK on the tutorial website it produced errors when I typed it in Idle. I visited the site quoted in the error message and as a result of information given there I downloaded and installed Wish 8.6 which has version Tcl 8.6 & Tk 8.6 (8.6.3) However I still got the same error message. I, therefore, uninstalled Python and downloaded it again from the Python website and reinstalled it in the hope that it would recognise the new version of Tcl/Tk. But, the same error message still appears. The program Idle does not seem to recognise that I have Tcl8.6 &Tk 8.6.3 installed instead of Tcl/Tk 8.5.9 There must be a simple error I am making, but I do not know what it is. This is the first time that I have tried anything like programming and I would appreciate assistance if possible. Kind Regards Peter McCahy

A few more comments. http://bugs.python.org/review/19548/diff/13502/Doc/library/codecs.rst File Doc/library/codecs.rst (right): http://bugs.python.org/review/19548/diff/13502/Doc/library/codecs.rst#newco… Doc/library/codecs.rst:420: Codec Objects Still the relation between the `codec` term and the Codec class/objects is not clear IMHO. http://bugs.python.org/review/19548/diff/13502/Doc/library/codecs.rst#newco… Doc/library/codecs.rst:829: :term:`text encoding` and recreating the A see some term confusion here: the `text encoding` term is defined (in the glossary) just as a *kind of* *codec*, buy *here* the words `encoding` and `decoding` refer to activities (each being a reversal of the other) performed *by* a *codec*. http://bugs.python.org/review/19548/

Inaccuracy in the description of factorial function
by Sergey Skovorodkin 29 Dec '14

29 Dec '14

Documentation of math.factorial function says [1]: > Raises ValueError if x is not integral or is negative. It should be changed to: > Raises ValueError if x is negative or TypeError if it is not integral. It's applicable for Python versions 2.7 and 3.4. I didn't check it for other versions.

A few remarks from a perspective of a person who still does not understand all nooks and crannies of the Python codecs system and the *codecs* module. http://bugs.python.org/review/19548/diff/13486/Doc/library/codecs.rst File Doc/library/codecs.rst (right): http://bugs.python.org/review/19548/diff/13486/Doc/library/codecs.rst#newco… Doc/library/codecs.rst:24: but there are also codecs that encode text to text, and bytes to bytes. Shouldn't be a note about arbitrary-types codecs added *here*? http://bugs.python.org/review/19548/diff/13486/Doc/library/codecs.rst#newco… Doc/library/codecs.rst:164: .. function:: register_error(name, error_handler) For this function and the functions described below, the above sentence "To simplify access to the various codecs, the module provides these additional functions which use :func:`lookup` for the codec lookup:" (line 112) is not appropriate. Some other sentence should be placed here (introducing error-handling-related functions. http://bugs.python.org/review/19548/diff/13486/Doc/library/codecs.rst#newco… Doc/library/codecs.rst:182: Decoding and translating works similarly, except :exc:`UnicodeDecodeError` or Possible beginner's questions: What is "translating"? When it is performed? How can it be differentiated from subsequent encoding + decoding? http://bugs.python.org/review/19548/diff/13486/Doc/library/codecs.rst#newco… Doc/library/codecs.rst:250: :func:`open` function; the ``'b'`` is automatically added. I would add something like: "Please note that when you need to use just an ordinary :term:`text encoding` the built-in :func:`open` function is the recommended (and, typically, more efficient) way to operate on text files". http://bugs.python.org/review/19548/diff/13486/Doc/library/codecs.rst#newco… Doc/library/codecs.rst:325: .. _surrogateescape: Should be moved to the place above the ".. _error-handlers:" line (341). http://bugs.python.org/review/19548/diff/13486/Doc/library/codecs.rst#newco… Doc/library/codecs.rst:335: Each codec has to define four interfaces to make it usable as codec in Python: Possible beginner's questions: is a codec an instance of :class:`Codec`? Or of :class:`CodecInfo`? What does it mean that it define those *four* intefraces? How is it related to the stateless/incremental/decoder/encoder and stream writer/reader classes described below? Why here only *four* interfaces and not *six* interfaces are mentioned? (i.e., what about *incremental encoder* and *incremental decoder?*) http://bugs.python.org/review/19548/diff/13486/Doc/library/codecs.rst#newco… Doc/library/codecs.rst:687: providing the *errors* keyword argument. These parameters are defined: The "parameters" word does not seem to be the correct term here... http://bugs.python.org/review/19548/diff/13486/Doc/library/codecs.rst#newco… Doc/library/codecs.rst:689: * ``'strict'`` Raise :exc:`ValueError` (or a subclass); this is the default. Only these three and not, e.g. 'surrogateescape'? Shouldn't be a reference to ".. _error-handlers:" be used here instead of this enumeration? (with a caution that the "only for encoding" handlers are disallowed) http://bugs.python.org/review/19548/

[issue22673] document the special features (eg: fdclose=False) of the standard streams
by Akira Li 25 Dec '14

25 Dec '14

Akira Li added the comment: Two minor details: 1. It is possible that `fileno(stdout) != 1` even in C [1]. I don't know what happens if the code from the answer is run on Windows. In principle, it may break eryksun's workaround. I don't know how likely it is in practice. 2. you can redirect at the file descriptor level in Python [2] using os.dup2(). I don't know whether the code in the answer works on Windows.
