Sorry -- too big a brain blip this morning.. my experiments were'n't actually creating dataclasses properly. Though it does show why the reliance on type hinting in troubling!! IGNORE that message!

Re: [Python-Dev] [RELEASED] Python 3.4.8 and Python 3.5.5 are now available
by Larry Hastings Feb. 11, 2018

Actually, it was updated on the server, but somehow the old version was sticking around in the CDN cache. I "purged" it and it's fine now. Weird that it would linger this long!

How to set/update value in a xml file using requests in python
by Sum J Feb. 8, 2018

Feb. 8, 2018

My xml file is located in local network: http://192.168.43.109/DevMgmt/NetAppsDyn.xml Below is a part content of above xml I want to update : <nadyn:NetAppsDyn> <nadyn:ProxyConfig> <dd:ResourceURI/> <dd:Port/> <dd:ProxySupport>off</dd:ProxySupport> </nadyn:ProxyConfig> </nadyn:NetAppsDyn> I want to set the value for 'ResourceUI' and 'Port' field in above xml. I have used below code : import requests data = { 'ResourceURI':'web-proxy.xxx.yy.com', 'Port':8080 } URL = 'http://192.168.75.165/DevMgmt/NetAppsDyn.xml' # content type head = {'Content-type': 'text/xml'} # sending get request gr= requests.get(url=URL) print gr # sending put request r = requests.put(url=URL, data=data,headers=head) print r.status_code # extracting response text output_xml = r.text print("The op xml is:%s" % output_xml) Issue : The fields are not getting updated in xml using put request. I am able to see the response for get (request) , but for put request it is throwing errror code : 301 , resource has been moved permanently.

Dataclasses and correct hashability
by Elvis Pranskevichus Feb. 7, 2018

Feb. 7, 2018

There appears to be a critical omission from the current dataclass implementation: it does not make hash=True fields immutable. Per Python spec: "the implementation of hashable collections requires that a key’s hash value is immutable (if the object’s hash value changes, it will be in the wrong hash bucket)" Yet: import dataclasses @dataclasses.dataclass(hash=True) class A: foo: int = dataclasses.field(hash=True, compare=True) a = A(foo=1) s = set() s.add(a) # s == {a} a.foo = 2 print(a in s) print({a} == s} print(s == s) # prints False False True This looks to me like a clearly wrong behavior.

It seems to be more focused on JIT compiling with many of its functions written for special cases and I did not find a way to make experimental changes easily. I even tried (briefly) to have the main loop of this interpreter run in RPython but didn't find enough information on which subset of Python does RPython handle. > Can you give an example of how you would do that?

Suppose I wanted to add a new clause to for...else, let's say: > > for ... : > block > otherwise: > # runs only if the for-loop was empty > > How would do I do that? > Here's one way to do that. Sorry for the lack of doc for the moment. To alter the language's grammar, you'd create a string with the new grammar, parse it and set the result to pyterp.parser. Then, depending on how the grammar was changed (which affects what AST is created), you'd change the corresponding function to handle the new semantics. I didn't quite understand what you mean by "was empty". However, I noticed that "else" blocks after for are ignored in the current implement. Here's an example session adding "else". If you tell me a bit more about the intended behaviour of "otherwise", I'd be happy to do an example with that clause. $ ipython -i test/python_repl.py p>> simport simple_ast p>> for i in [1, 2]: ... print i ... 1 2 p>> for i in [1, 2, 3]: ... print i ... else: ... print 100 ... 1 2 3 p>> ^D In the above for loop, the else block is ignored! I press Control-D to exist the interpreter. In [1]: grammar = python_grammar.full_definition + python_grammar.extra In [2]: grammar += r""" ...: for_stmt = "for" {exprlist} "in" {testlist} ":" {suite} {(SAME_INDENT "else" ":" {suite}) | void=pass_stmt} ...: """ In [3]: pyterp.parser = python.Interpreter(i3.parse("grammar", grammar)) In [4]: pyterp.repl() Now edit for_stmt in simple_ast.py except StopIteration: + evaluate(else_block) return (If else_block was not already an (ignored) parameter, we'd have to change the `def for_stmt...` line too.) And run in the REPL we just restarted. p>> simple_ast.reload_module(simple_ast) p>> for i in [1, 2, 3]: ... print i ... else: ... print 100 ... 1 2 3 100 p>> for i in [1, 2, 3]: ... print i ... break ... else: ... print 100 ... 1 p>> Some notes: 1. I'm using the host Python interpreter to change the grammar here but that's not strictly necessary if we expose pyterp itself in the global scope. 2. I'm editing simple_ast.py and reloading because its less changes but redefining a new function and setting simple_ast.for_stmt (in other words, monkey-patching the change) should also work. If we wanted an "otherwise" clause on top of an "else" clause, we probably want to make some provision for the runtime to distinguish between the two so I'd edit the grammar with something like for_stmt = "for" {exprlist} "in" {testlist} ":" {suite} {((SAME_INDENT "else" ":" {suite}) | void=pass_stmt)=else_block ((SAME_INDENT "otherwise" ":" {suite}) | void=pass_stmt)=otherwise_block} (In this case, "otherwise" blocks have to come after the "else" block if both are present.) asrp _______________________________________________ Python-Dev mailing list Python-Dev(a)python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/rymg19%40gmail.com

A minimal Python interpreter written in Python for experimenting with language changes
by asrp asrp Feb. 6, 2018

Feb. 6, 2018

Hello, I don't know if this is the right place to post this. Please redirect as needed. I've made a small Python interpreter in Python with runtime AST node semantics and edit-and-continue. I thought it could make prototyping language changes more easily and visualize usage before writing them in C. Its here: https://github.com/asrp/python_terp So, for example, redefining the for_stmt function in the right scope changes the behaviour of future for loops at runtime. Although from discussion I've read in PEPs, actual implementation always look like a non-issue (which seems like magic to me) so maybe no-one here actually needs this. (I really needed edit-and-continue for one of my projects but of course, running it in this extra interpreter is much too slow.) asrp

Dataclasses and correct hashability

This `unsafe_hash` argument will constantly raise questions among ordinary users like me, and will be possibly considered as a non-obvious design - there is a public API but it is somehow unsafe. On the other hand, with a function, when the user asks how to make a `frozen=False` dataclass hashable, you can suggest to use this `make_unsafe_hash` function with all its cautions in its docs or to try to implement __hash__ by yourself. Also taking into account the Python approach for backward compatibility it is better to stick with function and if it will be usefull to add a `unsafe_hash` argument in Python 3.8. It is easier to add later than to deprecate in the future. With kind regards, -gdg

libxml2 installation/binding issue

Hello, I am not sure if this is the correct place to post an issue/question like this, but here goes... I've successfully (?) installed Python 3.6.4 and libxml2, with the ultimate goal of installing GTK+ 3.22.0. However, I'm running into this error: python3 Python 3.6.4 (default, Feb 5 2018, 13:28:04) [GCC 4.7.2] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import libxml2 Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/nfs/sc/disks/slx_1353/mlpriest/sl1/work_root/a0/development/sfwr/lib/python3.6/site-packages/libxml2.py", line 1, in <module> import libxml2mod ImportError: /nfs/sc/disks/slx_1353/mlpriest/sl1/work_root/a0/development/sfwr/lib/python3.6/site-packages/libxml2mod.so: undefined symbol: _PyVerify_fd Here are the details on the version, cflags, and ldflags. python3 --version ; Python 3.6.4 python3-config --cflags -I/nfs/sc/disks/slx_1353/mlpriest/sl1/work_root/a0/development/sfwr/include/python3.6m -I/nfs/sc/disks/slx_1353/mlpriest/sl1/work_root/a0/development/sfwr/include/python3.6m -Wno-unused-result -Wsign-compare -fPIC -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes python3-config -ldflags; -L/nfs/sc/disks/slx_1353/mlpriest/sl1/work_root/a0/development/sfwr/lib/python3.6/config-3.6m-x86_64-linux-gnu -L/nfs/sc/disks/slx_1353/mlpriest/sl1/work_root/a0/development/sfwr/lib -lpython3.6m -lpthread -ldl -lutil -lrt -lm -Xlinker -export-dynamic Anyhelp or hint would be appreciated...

[RELEASE] Python 3.7.0b1 is now available for testing
by Ned Deily Feb. 5, 2018

Feb. 5, 2018

On behalf of the Python development community and the Python 3.7 release team, I'm happy to announce the availability of Python 3.7.0b1. b1 is the first of four planned beta releases of Python 3.7, the next major release of Python, and marks the end of the feature development phase for 3.7. You can find Python 3.7.0b1 here: https://www.python.org/downloads/release/python-370b1/ Among the new major new features in Python 3.7 are: * PEP 538, Coercing the legacy C locale to a UTF-8 based locale * PEP 539, A New C-API for Thread-Local Storage in CPython * PEP 540, UTF-8 mode * PEP 552, Deterministic pyc * PEP 553, Built-in breakpoint() * PEP 557, Data Classes * PEP 560, Core support for typing module and generic types * PEP 562, Module __getattr__ and __dir__ * PEP 563, Postponed Evaluation of Annotations * PEP 564, Time functions with nanosecond resolution * PEP 565, Show DeprecationWarning in __main__ * PEP 567, Context Variables Please see "What’s New In Python 3.7" for more information. Additional documentation for these features and for other changes will be provided during the beta phase. https://docs.python.org/3.7/whatsnew/3.7.html Beta releases are intended to give you the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. We strongly encourage you to test your projects with 3.7 during the beta phase and report issues found to https://bugs.python.org as soon as possible. While the release is feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (2018-05-21). Our goal is have no ABI changes after beta 3 and no code changes after rc1. To achieve that, it will be extremely important to get as much exposure for 3.7 as possible during the beta phase. Attention macOS users: with 3.7.0b1, we are providing a choice of two binary installers. The new variant provides a 64-bit-only version for macOS 10.9 and later systems; this variant also now includes its own built-in version of Tcl/Tk 8.6. We welcome your feedback. Please keep in mind that this is a preview release and its use is not recommended for production environments. The next planned release of Python 3.7 will be 3.7.0b2, currently scheduled for 2018-02-26. More information about the release schedule can be found here: https://www.python.org/dev/peps/pep-0537/ -- Ned Deily nad(a)python.org -- []
