[issue43786] slice(None) is slice(None) is False
New submission from Nico Schlömer : I stumbled upon this when dealing with NumPy arrays: ``` slice(None) is slice(None) ``` ``` False ``` This came up when trying to check if a variable `a` equals `slice(None)`. The comparison ``` a = slice(None) a == slice(None) ``` ``` True ``` works, but doesn't return a single Boolean if a is a NumPy array, for example. Perhaps there's another way of finding out if a variable is exactly `slice(None)`, but the failure of `is` seems like a bug. -- messages: 390598 nosy: nschloe priority: normal severity: normal status: open title: slice(None) is slice(None) is False ___ Python tracker <https://bugs.python.org/issue43786> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue41386] Popen.wait does not account for negative return codes
Nico added the comment: Yeah I see the point. To me it does make no sense because even in the windows API they seam to not know whether to use a ulong or a uint nor does this reflect the actual depiction within the program. However it is probably not worth implementing a flag for that nor to change the behavior entirely. This will create more problems than it would fix ambiguity.

[issue41386] Popen.wait does not account for negative return codes
New submission from Nico : Following problem occurred. A C style program can have negative return codes. However this is not correctly implemented in the Windows API. Therefore it is being returned as unsigned long by the API hence it leads to ambiguity while comparing return codes.

[issue29522] PyLong_AsDouble Behaviour is Weird
New submission from nico:
I'm using the pre-installed version of Python 2.7.12 on Ubuntu 16.04. Pretty
straight forward error the following code:
PyObject * intobj = PyInt_FromLong(10);
double d1 = (double)PyLong_AsLong(intobj);
double d2 = PyLong_AsDouble(intobj);
printf("Should be the same: %f vs %f", d1, d2);
Does not display the same number for both double since `PyLong_AsDouble` raises
the error, SystemError: ../Objects/longobject.c:2336: bad argument to internal
function and returns -1.0 instead of 10.0.

[issue8609] itertools: problem with nested groupby, list()
New submission from Nico nico.schloe...@gmail.com:
Hi,
I ran into a bit of an unexpected issue here with itertools.
I need to say that I discovered itertools only recently, and that maybe my way
of approaching the problem is not what I want to do. If you think this may be
the case, please let me know.
Anyway, the problem is the following:
I have a list of dictionaries, something like
[ { a: 1, b: 1, c: 3 },
{ a: 1, b: 1, c: 4 },
...
]
and I'd like to iterate through all items with, e.g., a:1. What I do is sort
and then groupby,
my_list.sort( key=operator.itemgetter('a') )
my_list_grouped = itertools.groupby( my_list, operator.itemgetter('a') )
and then just very simply iterate over my_list_grouped,
for my_item in my_list_grouped:
# do something with my_item[0], my_item[1]
Now, inside this loop I'd like to again iterate over all items with the same
'b'-value -- no problem, just do the above inside the loop:
for my_item in my_list_grouped:
# group by keyword b
my_list2 = list( my_item[1] )
my_list2.sort( key=operator.itemgetter('b') )
my_list_grouped = itertools.groupby( my_list2, operator.itemgetter('b')
)
for e in my_list_grouped:
# do something with e[0], e[1]
That seems to work all right.
Now, the problem occurs when this all is wrapped into an outer loop, such as
for k in [ 'first pass', 'second pass' ]:
for my_item in my_list_grouped:
# bla, the above
To be able to iterate more than once through my_list_grouped, I have to convert
it into a list first, so outside all loops, I go like
my_list.sort( key=operator.itemgetter('a') )
my_list_grouped = itertools.groupby( my_list, operator.itemgetter('a') )
my_list_grouped = list( my_list_grouped )
This, however, makes it impossible to do the inner sort and groupby-operation;
you just get the very first element, and that's it.
An example file is attached.
Is there anything that I can do to debug?
Cheers,
Nico
