[issue35006] itertools.combinations has wrong type when using the typing package
New submission from Vaibhav Karve : If I run mypy on the following file called test.py, I get an error: # test.py from typing import Iterator, Tuple import itertools as it a : Iterator[Tuple[int, ...]] a = it.product([1,2,3], repeat = 2) b : Iterator[Tuple[int, ...]] b = it.combinations([1,2,3], 2) The line about a goes through without complain. But mypy complains about b by printing the following error message-- test.py:8: error: Incompatible types in assignment (expression has type "Iterable[Tuple[int, ...]]", variable has type "Iterator[Tuple[int, ...]]") test.py:8: note: 'Iterable' is missing following 'Iterator' protocol member: test.py:8: note: __next__ So basically, it.product is an Iterator but it.combinations is an Iterable (I think it should be an iterator too). I think (without a lot of evidence) that this is a bug in itertools and not in typing. PS: I apologize if my comment is not formatted according to best practices.

[issue31590] CSV module incorrectly treats escaped newlines as new records if unquoted
Vaibhav Mallya <vaibhavmal...@gmail.com> added the comment: Hello R. David & Terry! Appreciate your prompt responses. While experimenting with different test cases I realized that escaped slashes and newlines are intrinsically annoying to reason about as stringy-one-liners, so I threw together a small tarball test case - attached - to make sure we're on the same page. To be clear, I was referring *solely* to reading with csv.DictReader (we're not using the writing part). The assertion for the multi_line_csv_unquoted fails, and I believe it should succeed. I hadn't considered the design-bug vs code-bug angle. I also think that documenting this somehow - explicitly - would help others, since there's no mention of the interaction here, with what should be a fairly common use-case. It might even make sense to make a "strong recommendation" that everything is quoted + escaped (much as redshift makes a strong recommendation to escape). Our data pipeline is doing fine after the right parameters on both sides, this is more about improving Python for the rest of the community. Thanks for your help, I will of course respect any decision you make. -- Added file: https://bugs.python.org/file47181/csv_test.tar ___ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue31590> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue31590] CSV module incorrectly treats escaped newlines as new records if unquoted
New submission from Vaibhav Mallya: I'm writing python `csv` based-parsers as part of a data processing pipeline that includes Redshift and other data stores upstream and down. It's easy and expected in all of these data stores (http://docs.aws.amazon.com/redshift/latest/dg/r_UNLOAD.html) that CSV-style data can be generated with ESCAPE'd newlines, and with or without quotes on the columns. Challenge: However, 2.x CSV module has a bug where ESCAPE'd newlines in unquoted CSVs are not actually treated as escaped newlines, but as entirely new record entries. This is at odds with expected behavior in most common data warehouses (See - Redshift docs I linked above for example) and is a subtle source of bugs for data processing pipelines. We changed our Redshift Parameters to ADDQUOTES so we could get around this bug, after some debugging. Note - This seems to be a continuation of https://bugs.python.org/issue15927 which was closed as WONTFIX for 2.x. I think this is a legitimate bug, and should be fixed in 2.x. If someone is relying on old / bad behavior might mean something else is wrong. In my view, the current behavior effectively adds an implicit, undocumented dialect to the CSV module. -- components: Library (Lib) messages: 303025 nosy: mallyvai priority: normal severity: normal status: open title: CSV module incorrectly treats escaped newlines as new records if unquoted type: behavior versions: Python 2.7 ___ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue31590> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue6009] optparse docs say 'default' keyword is deprecated but uses it in most examples
New submission from Vaibhav Mallya mally...@umich.edu: The first example, and several subsequent examples later on in the optparse docs, use 'default' as an argument, even though it's apparently deprecated in favor of set_defaults. At the risk of overstating the obvious, this seems to be inconsistent. Even the section on defaults http://docs.python.org/library/optparse.html#default-values uses the 'default' keyword without stressing its deprecation.

[issue5857] Return namedtuples from tokenize token generator
New submission from Vaibhav Mallya mally...@umich.edu: Returning an anonymous 5-tuple seems like a suboptimal interface since it's so easy to accidentally confuse, for example, the indices of start and end. I've used tokenize.py for several scripts in the past few weeks and I've always ended up writing some sort of wrapper function for generate_tokens that names the returned tuple's fields to help me avoid mistakes like this. I'd like to propose the following patch that simply decorates the generate_token function and names its return values' fields. Since it's a namedtuple, it should be fully backwards compatible with the existing interface, but also allow member access via next_token.type next_token.string next_token.start.row, next_token.start.col next_token.end.row, next_token.end.col next_token.line If this seems like a reasonable way to do things, I'd be happy to submit relevant doc patches as well as the corresponding patch for 3.0. -- components: Library (Lib) files: mallyvai_tokenize.patch keywords: patch messages: 86691 nosy: mallyvai severity: normal status: open title: Return namedtuples from tokenize token generator type: feature request versions: Python 2.6, Python 2.7, Python 3.0, Python 3.1 Added file: http://bugs.python.org/file13797/mallyvai_tokenize.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5857 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue5857] Return namedtuples from tokenize token generator
Vaibhav Mallya mally...@umich.edu added the comment: Well, the reason I put in the inner row/col namedtuple initially was because the first mistake I made with the original module was mixing up the row/col indices for a particular case. It certainly caused all sorts of weird headaches. :o) I mean, it seems like there's no real reason it should be (row,col) instead of (col,row) in the returned tuple; that is, it feels like the ordering is arbitrary in and of itself. I really feel that allowing for start.row and start.col would make the interface completely explicit and valid semantically. Agreed with the other two points, however. Also, I take it there's going to be a need for an addendum to the test suite, since the interface is being modified? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5857 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue5573] multiprocessing Pipe poll() and recv() semantics.
Vaibhav Mallya mally...@umich.edu added the comment: On second thought, it seems like it shouldn't make sense. This forces a destructive check. Suppose we do child.poll() and then child.recv() but it's legitimate data; that data will be removed from the queue even if we just wanted to check if the pipe was alive. This seems like it shouldn't have to happen. I'm unfamiliar with the lower level workings of sockets; is this destructive checking behavior forced by the socket internals?

Re: import woe
Hi bob,
1. decide the directory which will be your root folder containing foo
[/home/ROOT/foo/]
2. work out your directory structure relative to this root folder
here it is -ROOT-foo-car.py
-bar-far.py
-bar-jar.py
3. add __init__.py file inside each folder containing a list variable
__all__ with contents as the name of the directories and classes
so foo folder should contain a file called __init__.py which has the
following contents
__all__ = ['bar','car']
and bar folder should contain a file called __init__.py which has the
following contents
__all__ = ['far','jar']
4. add the root folder to your sys.path
so your jar.py file should have the following entries
from sys import path
path.append('../../../ROOT')
note: i prefer relative paths or make paths using os.getcwd
combinations in such situations, which makes the class more flexible.
you can also do this step where u configure/initialize
5. then you can import the classes you want in jar.py
from foo import car
from foo.bar import far
pls mail if u dont get it working/any doubts.
