Re: Python 3.5, bytes, and %-interpolation (aka PEP 461)

However, you don't really want to be adding large numbers of byte strings

all at once. Hence the push to add % to bytes in Python 3.

Interpolation will not help.

Re: Coding a simple state machine in python
Peter Otten __pete...@web.de:
Why have the function return a name? Why not just another function?
As people have said, there are many ways to skin the cat.
A function can represent a state if it is the only type of event the
state machine must process. A regular expression parser would be an
example.
In the general case, a state machine is a matrix of M states by N types
of event. Then, one natural manner of representing a state is a nested
class:
class Lackey:
def __init__(self):
lackey = self
class Idle:
def handle_ding(self):
lackey.start_timer(10)
lackey.set_state(Dinged)
class Dinged:
def handle_dong(self):
lackey.cancel_timer()
lackey.open_door()
lackey.ask_for_name()
lackey.start_timer(20)
lackey.set_state(AwaitingName)
def handle_timeout(self):
lackey.open_door()
lackey.shoo_visitor_away()
lackey.set_state(Annoyed)
# other state classes here...
self.set_state(Idle)
def set_state(self, state):
log(Lackey(): New state: {}.format(
id(self), state.__class__.__name__))
self.state = state()
def handle_ding(self):
self.state.handle_ding()

How would you define them?
E. g.
{1, 2} {2, 3} == {2}
but
{1:a, 2:b, 3:c} {2:b, 3:e, 4:f} == ???
The most obvious result is probably the empty dict {2:b}, i. e.
a b is defined as dict(a.items() b.items())

I can see (at least) two possible correct answers.
I would propose at least four:
{'A': 1} # choose the LHS
{'A': 2} # choose the RHS
{'A': (1,2)} # a resulting pair of both
set(['A']) # you did set-ops, so you get a set
If dicts were to support set ops, the last one would be my preferred
result.
I just had to perform set operations on a pair of dicts earlier this
week, shrugged, and did things the manual/explicit way:
a_dict = dict(...)
b_dict = dict(...)
a_set = set(a_dict)
b_set = set(b_dict)
added_keys = b_set - a_set
removed_keys = a_set - b_set
same_keys = a_set b_set
diff_keys = a_set ^ b_set
all_keys = a_set | b_set
It would save some space if I didn't have to duplicate all the keys
into sets (on the order of 10-100k small strings), instead being able
to directly perform the set-ops on the dicts. But otherwise, it was
pretty readable straight-forward.

I can see (at least) two possible correct answers.
I would propose at least four:
{'A': 1} # choose the LHS
{'A': 2} # choose the RHS
{'A': (1,2)} # a resulting pair of both
set(['A']) # you did set-ops, so you get a set
If dicts were to support set ops,
They do in 2.7 and 3.x.
the last one would be my preferred
result.
I just had to perform set operations on a pair of dicts earlier this
week, shrugged, and did things the manual/explicit way:
a_dict = dict(...)
b_dict = dict(...)
a_set = set(a_dict)
b_set = set(b_dict)
added_keys = b_set - a_set
removed_keys = a_set - b_set
same_keys = a_set b_set
diff_keys = a_set ^ b_set
all_keys = a_set | b_set
a = dict.fromkeys(ab)
b = dict.fromkeys(bc)
a.viewkeys() - b.viewkeys()
set(['a'])
a.viewkeys() b.viewkeys()
set(['b'])
a.viewkeys() ^ b.viewkeys()
set(['a', 'c'])
a.viewkeys() | b.viewkeys()
set(['a', 'c', 'b'])
For 3.x replace viewkeys() with keys().
It would save some space if I didn't have to duplicate all the keys
into sets (on the order of 10-100k small strings), instead being able
to directly perform the set-ops on the dicts. But otherwise, it was
pretty readable straight-forward.

The implementation should define if LHS or RHS and user should change the
order of operands depending on what he wants.
Your example (as well as a many questions in stackoverflow.com) shows
that there is some need for these operations, that implemented in C in
python library will be by far more CPU and memory efficient than
implemented as you did.

Re: intersection, union, difference, symmetric difference for dictionaries
{1, 2} {2, 3} == {2}
In my mind the intersection is evaluated on keys, so the resulting dict
should be the empty one
but
{1:a, 2:b, 3:c} {2:b, 3:e, 4:f} == ???
my output will be
{2:b, 3:e}
or
{2:b, 3:c}
depending on the implementation choice.
The most obvious result is probably the empty dict {2:b}, i. e.
a b is defined as dict(a.items() b.items())
Frankly, I don't do that a lot. So what's your use-case?
I do not have an use case, but I've seen that many people ask for these

The set hash table takes 20-40 bytes per entry on this computer (according to sys.getsizeof). On the same system a short string takes a similar amount of memory. The .keys() view object apparently takes 24 bytes in total so yes it's a reasonable memory saving if the dicts or of any significant size. However the .keys() objects are not necessarily as well optimised so it may be faster to convert to sets for some operations. One example I found some time ago is that for sets A B will iterate over the smaller set but for dicts A.keys() B.keys() would always go over the left-hand set (or right-hand - I don't remember). This makes a considerable difference if one set is significantly larger than the other. Oscar -- https://mail.python.org/mailman/listinfo/python-list

No, I disagree. If you want a set, it's easy to do:
dicta.keys() | dictb.keys()
(In Python 2, use viewkeys instead.)
gives you a set of the intersection of the keys. The only point of having
dicts support set-like operations directly is if you get a dict back.
All of these operations are quite simple to write, so personally I would
recommend people just add their own helper function with the behaviour
they prefer.

Set elements are unique, just like mapping keys. Specifically, the keys in a mapping make up a set; the values in a mapping do not. When talking specifically about Python dicts and sets, there is an additional restriction: both set elements and dict keys have to be hashable.

No, I disagree. If you want a set, it's easy to do:
dicta.keys() | dictb.keys()
(In Python 2, use viewkeys instead.)
Now that I'm aware of .viewkeys()/.keys() (herein vk/k for brevity)
thanks to Peter Otten's post, that does what I most commonly want for
set-ops-on-dicts. I'd just consider this a promotion, since
for k in my_dict:
pass
is the same as
for k in my_dict.keys(): # or .iterkeys() in 2.x
pass
I'd find it intuitive to have set-ops behave similarly, defaulting
to vk/k.
All of these operations are quite simple to write, so personally I
would recommend people just add their own helper function with the
behaviour they prefer.
And with vk/k, I now fall pretty firmly in agreement with you (except
for the aforementioned possibility of having a dict's currently-unused
set-ops use the results of vk/k as well).

[issue20727] Improved roundrobin itertools recipe
Gareth Rees added the comment: I suspect I messed up the timing I did yesterday, because today I find that 100 isn't large enough, but here's what I found today (in Python 3.3): from timeit import timeit test = [tuple(range(300))] + [()] * 100 timeit(lambda:list(roundrobin1(*test)), number=1) # old recipe 8.386148632998811 timeit(lambda:list(roundrobin2(*test)), number=1) # new recipe 16.757110453007044 The new recipe is more than twice as slow as the old in this case, and its performance gets relatively worse as you increase the number 300. I should add that I do recognise that the new recipe is better for nearly all cases (it's simpler as well as faster), but I want to point out an important feature of the old recipe, namely that it discards iterables as they are finished with, giving it worst-case O(n) performance (albeit slow) whereas the new recipe has worst case O(n^2). As we found out with hash tables, worst-case O(n^2) performance can be a problem when inputs are untrusted, so there are use cases where people might legitimately prefer an O(n) solution even if it's a bit slower in common cases. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20727 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue20766] reference leaks in pdb
New submission from Xavier de Gaye: After the pdb 'continue' command, the signal module owns a reference to Pdb.sigint_handler. On the next instantiation of pdb, the signal module owns a reference to a new sigint_handler method that owns a reference to the previous sigint_handler.

[issue20727] Improved roundrobin itertools recipe
Gareth Rees added the comment:
But now that I look at the code more carefully, the old recipe also has O(n^2)
behaviour, because cycle(islice(nexts, pending)) costs O(n) and is called O(n)
times. To have worst-case O(n) behaviour, you'd need something like this:
from collections import deque
def roundrobin3(*iterables):
roundrobin('ABC', 'D', 'EF') -- A D E B F C
nexts = deque(iter(it).__next__ for it in iterables)
while nexts:
try:
while True:
yield nexts[0]()
nexts.rotate(-1)
except StopIteration:
nexts.popleft()
from timeit import timeit
test = [tuple(range(1000))] + [()] * 1000

[issue20768] pyconfig.h #defines macros in global namespace
New submission from Felipe Sateler: I reported the following in the debian bug tracker[1], and it was requested that I report it here. pyconfig.h has definitions like the following: #define HAVE_DIRENT_H 1 #define HAVE_DLFCN_H 1 These are the general form feature test macros take in practically any software project. This means that when building a python module these feature macros conflict. In the best scenario, you get a redefinition warning. In the worst scenario, the build breaks because of inconsistent #defines between the module and pyconfig.h. Please either don't include pycongfig.h from Python.h, or appropiately namespace the test macros (PYTHON_HAVE_* or something like that).

Those HAVE_* macros are mostly standard autoconf macros, which you'll find in lots of libraries, not just Python. You can use them in your Python module as well, and of course, add more autoconf macros as needed using a separate .h file. C doesn't have namespaces like C++ does, so the only possible change would be to prefix all of those macros with PY_. Since this is the first time I've ever heard anyone complain about those macros, I doubt that this is a general problem. People are usually happy with building on the autoconf tests we already have in Python. -- nosy: +lemburg ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20768 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20770] Inform caller of smtplib STARTTLS failures
New submission from And Clover: When an SMTP server responds to the STARTTLS command with an error, the smtplib.SMTP.starttls() method does not raise an exception, as it would if TLS negotiation itself failed. Consequently naïve callers of the function may assume that a TLS connection has actually been established and continue to send sensitive mail through the interface. In reality starttls() returns a tuple of response code and message from which the fail state can be detected, but this is not documented and no caller code I've met does anything with it. Either: 1. Treat it as a doc bug for 3.4. The return value should be documented and callers warned that they need to check that value[0]==220 before assuming they have negotiated TLS. Or, 2. starttls() should raise SMTPResponseException for responses other than 220 in a future Python version, especially if moving towards validate-by-default. Possibly only raise an exception if the SSLContext.verify_mode is REQUIRED? -- components: Library (Lib) messages: 212192 nosy: aclover priority: normal severity: normal status: open title: Inform caller of smtplib STARTTLS failures type: behavior versions: Python 2.7, Python 3.1, Python 3.2, Python 3.3, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20770 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

I'll email the psrt about it. -- nosy: +r.david.murray ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20770 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Antoine Pitrou added the comment: It probably isn't a good idea to break the API, but this should certainly be documented. -- nosy: +pitrou ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20770 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20501] fileinput module will read whole file into memory when using fileinput.hook_encoded
Zachary Ware added the comment: Can anyone please test the patch on Windows? It seems to work; memory usage is much lower with the patch than without using an 8 MB file. I don't notice any behavioral change with the patch; if there's anything specific to look for on that front, give me a test script in either English or Python :) -- nosy: +zach.ware ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20501 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
