No, all you need is there in that example. You need to decorate your functions using Spyne's @rpc, denote input/output types using Spyne's type markers, wrap it inside a subclass of Spyne's ServiceBase, pass the resulting service class to a Spyne application setting your input/output protocols (you probably want Soap) and pass that application to a transport of your choice (you probably want WsgiApplication).

Python can download this from the internet; in fact, that's exactly what the pip install numpy command does. However, you have to be explicit. You don't want the simple import numpy command to go and install some third-party software; that would mean that mistyping it as import numpt would also attempt to install something new, and immediately run it.

Why my ; continuator idea is better for debugging too.
Hello, In the past I wrote about pascal's ; mistake. ; should be used as a continuator. I just made a programming mistake which solidifies/merits my idea: The programming mistake was this: vBattlefieldLosingWarrior := // modified warrior and brain vSimulatorWinningWarrior := vBattlefieldBattle.Warrior[0]; Code should look like this: vBattlefieldLosingWarrior := TBattlefieldWarrior(vBattlefieldBattle.Warrior[2].Association); // modified warrior and brain vSimulatorWinningWarrior := vBattlefieldBattle.Warrior[0]; Fortunately there was a type mistmatch which hinted me at the programming mistake. The code is a bit messy above so let's make a simpler example to understand, the in my oppinion, dangerous programming mistake: A := B := C; The above statements A := is valid in Delphi's current design. The danger is that B is assigned to A which is not what I wanted, the problem was missing code at A. So the danger is that some day, somebody will write B in such a way that it will accidently be assigned to A. By using ; as a continuator instead of a seperator the code would look as follows: A := B := C Since there was no continuator specified, future-Delphi would have been able to detect this programming mistake. Since it won't try to attach B to A since there is no continuator symbol. I found it worth it to mention this so there ya go. I am always glad when Delphi finds bugs like these... fortunately this time I got lucky thanks to a type mismatch. Also the statement would have looked like A:=B:=C; which I think is not a valid statement in Delphi. I ll test that just to be sure. Yes fortunately Delphi does not allow such dangerous statements. However I think C does, I am pretty sure of it. Another nice example why C is dangerous ! ;) (Also my request for python is the : symbol removed from language and instead require statements to be on next line below if statement that be nice) (Currently the : is perceived by me as unnecessary and annoying, an easy typo to make just like forgetting a ; however these are not necessary in python so why remove ; but not : ? seems inconsistent, and ya know me... I don't like inconsistencies, it's frikking annoying.). Bye, Skybuck. -- https://mail.python.org/mailman/listinfo/python-list

It seemed like everything was being downloaded and installed. Seems ok. Then I go back to the Python Shell and ran 'import numpy' 'import pandas' and I still get the errors that I got before. I gave you some instructions to try before, but you don't appear to have followed them. Let's try again: (1) First, confirm how many different versions of Python you have installed. Please don't reinstall Python again. That doesn't help, if anything it may make matters worse. I suggested that you try running the following commands from the DOS prompt (or C-prompt, if you prefer to call it that): python27 python33 python34 although not being an expert on Windows I'm not sure if there is a better way. Another way may be to use the Windows' Find Files command to look for any .exe files with python in the name. (2) Next, try installing numpy and pandas again, only this time don't use the --upgrade switch. COPY AND PASTE the output so we can see exactly what happened. (3) Try running the Python shell again. Tell us *what* Python shell you are using. Your tracebacks say pyshell#19 which is not standard. What are you actually running? Tell us *exactly* what steps you take to run the Python shell. (4) I think you are running some sort of IDE (Integrated Development Environment). Are you running a third-party system like Anaconda, or possible something like Spyder? If so, then I suggest you check whether that third-party system is causing the problem. From the C prompt, just run python and then try importing numpy and see what happens. Again, COPY AND PASTE any output. (5) Consider that unless you have a C compiler, and possibly a Fortran compiler, you may not be able to install numpy from source on your system. You may need to find some pre-built packages that match your version of Windows. -- Steven -- https://mail.python.org/mailman/listinfo/python-list

[issue23097] unittest can unnecessarily modify sys.path (and with the wrong case)
New submission from Chris Jerdonek: I have observed that when running unit tests using unittest's test discovery, unittest can simultaneously (1) modify sys.path unnecessarily (by adding a path that is already in sys.path with a different case), and (2) modify sys.path by adding a path of the wrong case. This occurs for me on Mac OS X with the default case-insensitive file system. If the path-- '/Users/chris/Dev/python/my_package' is already in sys.path, running unittest's test discovery will prepend sys.path with the following: '/Users/chris/dev/python/my_package' Aside from causing unnecessary modifications of sys.path, this also causes an issue in coverage, for example: https://bitbucket.org/ned/coveragepy/issue/348 The relevant code is here in unittest/loader.py (with `top_level_dir` starting out as os.curdir): top_level_dir = os.path.abspath(top_level_dir) if not top_level_dir in sys.path: # all test modules must be importable from the top level directory # should we *unconditionally* put the start directory in first # in sys.path to minimise likelihood of conflicts between installed # modules and development versions? sys.path.insert(0, top_level_dir) self._top_level_dir = top_level_dir (from https://hg.python.org/cpython/file/75ede5bec8db/Lib/unittest/loader.py#l259 ) The issue occurs when os.path.abspath(top_level_dir) is already in sys.path but with a different case. (Note that if os.path.abspath() returned a path with the right case, then the unittest code would be okay.) See also these two threads regarding obtaining the correct case for a path: 1. https://mail.python.org/pipermail/python-dev/2010-September/103823.html 2. https://mail.python.org/pipermail/python-ideas/2010-September/008153.html -- components: Library (Lib) messages: 232993 nosy: chris.jerdonek priority: normal severity: normal status: open title: unittest can unnecessarily modify sys.path (and with the wrong case) type: behavior versions: Python 3.4, Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23097 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue19539] The 'raw_unicode_escape' codec buggy + not appropriate for Python 3.x
Martin Panter added the comment: [Edit Error: 'utf8' codec can't decode byte 0xe2 in position 212: invalid continuation byte] Re-reading the suggested description, it struck me that for encoding, this is redundant with the “backslashreplace” error handler: test = .join(map(chr, range(sys.maxunicode + 1))) test.encode(raw-unicode-escape) == test.encode(latin-1, backslashreplace) True However, decoding also seems similar to “unicode_escape”, except that only \u and \U seem to be supported. Maybe there should be a warning that backslashes are not escaped: \\u005C.encode(raw-unicode-escape).decode(raw-unicode-escape) '\\' -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19539 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue23061] Update pep8 to specify explicitly 'module level' imports at top of file
Ian Lee added the comment: So one concern that was brought up on GitHub was the fact that currently this is not actually followed universally in the Python standard library. In particular there are 636 errors in the standard library ``python pep8.py --select E402 --statistics /usr/lib/python3.4``. The vast majority are due to issues with dunder definitions ``__{all,author,copyright,credits,version,etc...}__`` before the imports. A lesser cause is imports in the middle of files. ``Lib/tokenize.py`` has pretty much all of these issues. In particular ``__all__`` is specifically mentioned that it should be declared AFTER the imports by PEP-8. That said, I would argue this is a good time to clean up that code in the standard library. Additionally, its possible that there might need to be some wording in the PEP about intermixing try,except,else,finally and possibly if,elif,else into the imports. E.g. ``` try: import unittest2 except: import unittest ``` ``` if sys.platform == 'win32': import foo ``` -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue23061 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue21279] str.translate documentation incomplete
Serhiy Storchaka added the comment: Serhiy can you point out which bits are too verbose? Perhaps you prefer it without the bullet list like in the earlier 2014-12-13 version of the patch. I prefer it without the bullet list and without LookupError expansion (there is a link to LookupError definition where IndexError and KeyError should be mentioned). Instead of new term subscriptable objects use mappings or sequences with links to glossary. Looking at the C API, I see a couple problems there: Yes, it is slightly outdated and needs updates. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21279 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
