I don't need "social media" or a "social media app." Email works exceedingly well for this sort of thing, despite Google's antics. Sadly a lot of open source projects are abandoning the good old list and moving to awkward web forums like Discourse. With e-mail lists, everything is right here in my email client (Thunderbird), separated out into folders with procmail (or whatever filtering system you want), and with proper nesting of messages. No web forum I've seen offers this convenience or proper nesting. Electronic communication is fraught enough. "Social media" (whatever that means) seems to just make it harder. -- https://mail.python.org/mailman/listinfo/python-list

Issue with PYSFTP - Working in WINSCP
Hi
We have requirement where we need to get file from client path and then
upload the same to vendor directory path. I am not able to upload the file
to vendor directory path , however when I tried to use the WINSCP it worked
fine. So I thought of checking with Gurus what is wrong I am doing in my
script. Appreciate your input.
I will attach my script. Here is what I am doing.
Step1. Clear the client directory path
Step2. Make a call to HVAC Vault to get the username and password for
client and vendor server
Step3. Use the username and password to establish connection using pysftp
for client.
Step4. Store the file in local path.
Step5. Segregate the file into different path based on file type
Step6 Establish a connection to vendor and copy the file to vendor.
Step7 Close the client and Vendor connection
Please see the file attached.
Also below is the error which I am getting
-

But Python 3 returns a float, for example, in division between integers. 4 / 2 == 2.0. So some_integer / +0 should return +Infinity. This is what IEEE 754 says. Luckily Python does not adhere completely to IEEE 754. Furthermore, there's a precedence in Python: decimal. decimal.Decimal does not returns NaN in any of the operations that should return it: https://en.wikipedia.org/wiki/NaN#Operations_generating_NaN On the contrary, it returns decimal.InvalidOperation. @Alan Bawden: thank you for letting me know about William Kahan. I think it's analysis of IEEE 754 is very detailed, and I didn't know that traps exist. And yes, I agree that traps and exceptions slows down the computation. But in a language like Python, when simplicity and usability is a priority, and when "no exception should pass silently", IMHO operations that returns NaN are only an heritage from C, since Python is written in C.

Re: Installation of python
*Ahem* I already posted the solution to your problem. I quote myself: I suppose you also downloaded the required sources from here: https://data.mendeley.com/datasets/s2x4d542dc/1 It seems the problem is that the above sources are generated by an old version of Cython: https://github.com/mcfletch/pyopengl/issues/11 You have "simply" to enter any subdir of PoissonSolver that ends with "_cy" and remove the .c file inside them. After that, you'll be able to compile. The result is three ELF files. On my PC, for example, one of the the generated shared libraries is PoissonSolver/PoissonSolver/ps3d.cpython-38-x86_64-linux-gnu.so You have also to rename them. Follow the README.

Do you know about the Method Resolution Order (MRO) that is in
__class__.__mro__)?
I was very confused by super() until I found out about the MRO. When you call
super() it finds
where the code is in the MRO and then starts looking for a method in classes
before the calling
class.
The following code shows this:
class A:
def __init__(self):
super().__init__()
def fn(self):
return 'A.fn'
class B(A):
def __init__(self):
super().__init__()
class C(B):
def __init__(self):
super().__init__()
def fn(self):
return 'C.fn and super().fn is %r with value %r' % (super().fn,
super().fn())
class D(C):
def __init__(self):
super().__init__()
print(D.__mro__)
obj = D()
print( obj.fn() )
When it is run it prints:
(, , , , )
C.fn and super().fn is > with value 'A.fn'
When fn() is called on obj the version of fn() in class C is called.
That fn() calls the super().fn and the second print shows that its the class A
fn that is found called.
super starts with the next class after the one it is called in. It is in C so
find C in the MRO and starts with
B. B does not have an fn(). Then it looks in A and finds fn().
Is this what you are looking for?

In this case the code might want to use the threading.RLock that is reentrant. Of course there may be other issues in the code that prevent the finalizers working if it holds the lock.

Even in C, they are > expected to raise an exception or equivalent. Actually, its not that far from the truth to say that NaNs "exist to avoid exceptions". According to Kahan, NaNs were an improvement over previous NaN-like mechanisms that existed in older computer hardware precisely because they avoid exceptions. Kahan says of those older mechanisms: "But nobody used them because they trap when touched." I believe that signalling NaNs were added to the IEEE standard late in the process because people still wanted something you could store in a uninitialized variable that would trap if you accidentally used it. Unlike all the IEEE operations that result in a NaN, using an uninitialized variable is clearly an error. Kahan doesn't think much of signalling NaNs, writing that they "exist mainly for political reasons and are rarely used". -- Alan Bawden -- https://mail.python.org/mailman/listinfo/python-list

I think the fundamental insight is that given class A: foo = "A" class B(A): foo = "B" def super_foo(self): return super().foo def my_foo(self): return self.foo b = B() b.foo = "inst" print(b.super_foo()) # A print(b.my_foo()) # inst del b.foo print(b.my_foo()) # B del B.foo print(b.my_foo()) # A self.foo looks up the attribute in the instance, falls back to the class and then works its way up to the parent class, whereas super().foo bypasses both instance and class, and starts its lookup in the parent class. -- https://mail.python.org/mailman/listinfo/python-list

Even in C, they are expected to raise an exception or equivalent. Python raises an exception for float division by zero because Python does its best to treat smallish integers and integral floats as equivalent. (Yes, I'm using "smallish" to mean "less than nine quadrillion"... programmers have weird ideas about magnitude sometimes.) Apart from indexing, the values 3 and 3.0 should be able to be used pretty much interchangeably. They compare equal (which, in turn, implies that they have the same hash), they behave very similarly in arithmetic, etc, etc, etc. It makes good sense for division by 0 and division by 0.0 to both result in the same exception. It also makes sense for integer division to raise rather than return a float (since "x // y" between two ints will never otherwise be a float). So it'd be nastily inconsistent to return a NaN for float division by zero. ChrisA -- https://mail.python.org/mailman/listinfo/python-list

Little errata: you have only to install or update Cython, remove the .c files as I wrote before and run again python setup.py build_ext -b PoissonSolver/ No intermediate steps are required.

Re: [Python-ideas] Re: New explicit methods to trim strings
I agree with Steven D'Aprano. I never had problems with strip(), but if people find it confusing, Python can simply leave strip() and all the other function as they are and add another functions, like crop() or snip() or shear() prune() or mow(). Personally I prefer crop() or prune(). This way there will be no breaking changes.

Re: [Python-ideas] Re: Magnitude and ProtoMagnitude ABCs — primarily for argument validation
I think that implementing TotallyOrderable and PartiallyOrderable is a good idea. But is it useful? I mean, I don't know how much people needs really to order sets. Maybe some mathematician. But they can simply use Sage: http://doc.sagemath.org/html/en/reference/categories/sage/categories/posets.html The real problem is NaN. If NaN would not exists, floats will be perfectly total orderable. Yes, IEEE 754-2019 defines a total order: -NaN is a number minor that -Infinity, and +NaN is a number greater than +Infinity. And a NaN is greater than another NaN if its payload is greater. But IEEE 754 says also that the division by +0 should return +Infinity, and by -0 -Infinity. On the contrary, Python decided to not adhere to IEEE 754 in this case and do a very wise choice: raise an exception. The question is: why Python does not do the same for operations that now return NaN? Raising a NanError seems to me the only way to eliminate the NaN problem. Indeed NaN was created for languages like C, that does not support exceptions. -- https://mail.python.org/mailman/listinfo/python-list
