Hmmm...strange, I didn't see Rick's mail:-(

Sure the forward slash is better, not to cause this confusion.
But I am curious, since when, I mean, since which version
Windows start to accept forward slash?

Windows has always supported forward slashes in most contexts for
compatibility with UNIX software. (just not in cmd.exe IIRC)

Since MS-DOS 2.0, i.e., before Windows even existed. Note that this is
only true for system call paraeters[1], not for command line parameters. 

So for your use case:

you probably need to use backslashes, not forward slashes (it depends on
the program you are calling).

Notwithstanding Ethan's comment about having posted the suspension notice

Subject: Temporary Suspension
Date: Mon, 10 Sep 2018 07:09:04 -0700
From: Ethan Furman 
To: Python List Moderators 

As a list moderator, my goal for this list is to keep the list a useful
resource -- but what does "useful" mean?  To me it means a place that
python users can go to ask questions, get answers, offer advice, and all
without sarcasm, name-calling, and deliberate mis-understandings.
Conversations should stay mostly on-topic.

Due to hostile and inappropriate posts*, Steven D'Aprano is temporarily
suspended from Python List for a period of two months.

This suspension, along with past suspensions, is being taken only after
careful consideration and consultation with other Python moderators.

The goal is promoting respect and dignity within the workplace, and
more generally within our field. If you can't see how this advances
that, then I have nothing further to say. You might ask yourself,
though: why are you so invested in this that you would not only refuse
to change anything yourself, but also would throw up a resistance when
others try to make a simple documentation rewording?

One other thing. This is difficult for me to respond to, but I feel it
has to be done:

Yes, you can kick your computer across the room if it's not working.
The difference with a computer is that you don't have to; computers
are never willfully disobedient. Computers never have to be "broken"
in order to have value. Computers also don't have feelings or
experience pain. You can't punish a defiant computer by whipping it,
or starving it, or preventing it from sleeping, or making it sit in
its own waste. You can't punish it by separating it from its family or
keeping it in total isolation. You can't even just sell its family to
another computer-owner without even considering how it will feel about
that. You can't force a computer to adopt your own religion. You can't
lie to your computer in order to manipulate it. You can't make it a
promise of freedom that you know you will never keep.

If you think that a slave just means somebody who has no choice but to
do what they're told, then yes, I think that you're trivializing the
condition of slavery, and by comparing the victim to a simple object
like a computer, the very language that you're choosing is
dehumanizing.

If you mean how he sent an email to the mods instead of to the list,
that's a simple administrative error that anyone could make (and I
have myself made similar errors - sending Python emails to a Gilbert &
Sullivan list, and vice versa). If you mean the decision to put Steve

As a reader of /occasional contributor to, this newsgroup (via GG, admittedly)
since around the year 2000, I for one am mightily unimpressed with this.
There's a lot of heavy-handedness going around.

And then ... you make a mistake, and then restart the ban?? Sheesh, where has

That has been one of its hallmarks for the past nearly twenty years.

I mean that I have always thought that Ethan Furman was useless as a 
moderator.  Having said that with this latest disgraceful decision 
regarding Steven I believe all moderators should stand down as they all 
appear to be clueless, especially I don't recall getting asked who I 
wanted in the job.  If their defence is that they're applying the CoC to 
the letter then that should be rewritten be back the people who have in 
the long term supported Python, not the lazy, bone idle types who 
provide no data, no code, no nothing when asking their question, and the 
well known trolls who get away with blue murder who months or even years 
before they get kicked into touch.

Steven has been around for a long time, after a quick search it seems
for at least 15 years, I mean on python-list. He has consistently been
helpful and has dedicated an amazing number of man hours to altruistic
help of fellow python users, beginners, experts, etc.

I'm totally amazed by this decision to ban him. The official
explanation has referenced 2 potentially mildly problematic posts.

I guess the moderators do have and should have the power to ban people
but we all have the right to criticise these bans on a case by case
basis. I'm not implying that Ethan and the moderators who were
involved in the ban are doing a bad job in general, but in this
particular case it does seem hyper excessive.

Cheers,
Daniel

First, stop top posting.

Second, ISTR that all Windows NT versions and versions derived from the

Hi there,

import re

s = b'\tC:94.3%[S:89.9%,D:4.4%],F:1.7%,M:4.0%,n:1440\n'

pattern = re.compile('S:([0-9.]+)%,D:([0-9.]+)%\],F:([0-9.]+)%,M:([0-9.]+)')

stuff = [x for x in re.findall(pattern, s)[0]]

You may consider just getting everthing out of your string and then munging it 
to what ever you like.

I mean:

pattern = re.compile('([A-Za-z]):([0-9.]+)')
{x: float(y) for x, y in re.findall(pattern, s)


Then you could read what ever and put it in a handy format wherein it is clear 
what it was. I mean:

stuff = []
for s in iostream:
stuff.append({x: float(y) for x, y in re.findall(pattern, s)})

It's not "once", it's a long-standing pattern of behaviour.

It's not "weird" so much as it is "long overdue", but even I would say

Coming from a moderator of this forum, I don't know how that statement

Is that a statement that it is *impossible* (mechanically) to post
replies in this thread? Across the different technologies that propogate
this forum?

If not impossible, is that a statement that it is *strictly prohibited*,
by a forum moderator, to post replies in this thread?

If prohibited, what are we to expect are the consequences of breaching
that prohibition, knowingly or unknowingly?

How is any of the above affected by posting in the same thread but on a
different metter, as I have done?

How is any of the above affected by changing the Subject field, as I

If there is some specific formal meaning to the above statement, I don't
know where it's documented. If it's not a specific formal statement,
that is itself troubling, because it's not clear what would constitute a

Ethan, I thank you for doing the fraught work of a moderator of this

It should be interpreted as:

- No further discussion should take place on this thread.
- I've done what I can with the primitive tools at hand to block
  any further discussion.
- Continued considerate posts will be discarded.
- Continued flame-bait/inconsiderate posts will be met with warnings

If one tries to get around moderators' efforts to shut down a thread we 
will interpret that harshly.

Two factors come into play:

At this point the blocks are entirely based on subject lines (like I 
said, primitive).  If the new subject line still matches the relevant 
regex, then it will get held and we will decide what to do with it (I 
allowed this one as it had good questions -- in general, just start a 
new thread if the subject is different, as I did in this reply).


> How is any of the above affected by changing the Subject field, as I

If the subject is different enough it will get by the block.  If the 
content is still on the old subject we will consider that as willfully 
ignoring the thread closure.

Consider it now documented, at least on Python List.  I imagine Python 
Ideas may also implement this framework (assuming we stay on Mail Man 
and don't migrate to some web-based forum).

Let me know if anything is still unclear.

How to achieve pyc only deployment for module in python3.6

[Chandana Pattanayak]

Hi,

I have a requirement to provide basic code protection for a module in our
product suite. With python 3.6 the .pyc files are created under pycache ,
so if i remove the py file the module is not found anymore.

Thank you,
Chandana

Re: How to change '\\' to '\'

Thanks for your info about how Windows supports the forward slash.

I don't quit sure what is the meaning of "top posting" in your mail.
If its meaning (forgive me if I was wrong) is where the reply was put
in mail, I have reason of standing on the opposite side.

It was supposed that most discussant want to see the reply message
instantly when they open the mail. They already know what is going on
and no need to pass through all those previous message. "top posting"
seems more reasonable to me:-)

Sure the forward slash is better, not to cause this confusion.
But I am curious, since when, I mean, since which version
Windows start to accept forward slash?



First, stop top posting.

Second, ISTR that all Windows NT versions and versions derived from the 
NT codebase support forward slash in pathnames given to functions. It 
may go back further, but anything derived from NT works.  I can't 
remember which Windows command shells support it, probably PowerShell does.

Yes, exactly correct

The problem is that it is comparatively rare for there to be a singleton Q and 
immediate A.  Even seemingly simple questions frequently trigger fairly long 
discussions, which assume familiarity with the earlier discussion. AND this 
list is pretty much the place of record for people researching python IFAQs 
(infrequently asked questions). So, six months from now a Google search that 
turns up a relevant thread will make sense only if it can be read as in-lined 
comments like this.

One approach could be to define and register your own
import hook, similar to the "zipimporter".
Such import hooks allow to find modules in non standard places,
such as in a zip archive.
Of course, you would need to implement the import hook in
a standard place (accessible with the standard Python import mechanism).

Another approach could be, that you move the created "*.pyc" files
to standard import places for deployment.


Note that you can disassemble "*.pyc" files and gain
quite some insight by this. Thus, the protection provided
by not deploying the source files is basic indeed.

If you want code protection, the ONLY reliable way to do it is to not
provide the code *at all*, in any form. That generally means hosting
your application on some sort of server and granting access that way
(eg through a web browser interface). Shipping only .pyc files does
not protect your code - it merely obscures it a little.

I suggest changing the requirement. Otherwise, you're running a huge
risk that someone will decompile your pyc files, word will get back to
your company, and you'll get in trouble for having deceived people
into thinking that the code was protected when it actually wasn't.

You should also read "https://www.python.org/dev/peps/pep-3147/";.
It mainly explains why "pycache" has been introduced
but as a side effect, it points out a bondage between
the "*.pyc" files and the major Python version: it is very likely,
that a major Python version will not accept "*.pyc" files created
by another major Python version.

You assume that everybody who reads it has already read all the previous 
discussion. That may be true in a private discussion, but on Usenet 
often people scan over the postings and don't recall all the details.


Also, "intermixed posting" makes it easier to reply to several points 
individually. You should shorten the quote to the releveant bit that 
your reply belongs to.


Classic quote:

A: Because it reverses the logical flow of conversation.

Q: Why is top posting frowned upon?

A: Top-posting.

Thank you all. I will go for containers. Will ask for more time based on
all your inputs..

Thanks,

Even for two-person, private email discussions I prefer the interleaved 
replies -- in a week when I have to remind myself what was discussed it 
is much easier to comprehend.

Yes.  It is extremely annoying when someone top posts and leaves the 
entire rest of the discussion still attached at the bottom.
