But you have seen writestr(), haven't you?

ZipFile.writestr(zinfo_or_arcname, data, compress_type=None,
compresslevel=None)

Write a file into the archive. The contents is data, which may be
either a str or a bytes instance;

No your're not. writestr() and ZipInfo are your friends, unless I
haven't understood what you're trying to do.

I beleive it comes from the web server. Here it is:

Error: 500 Internal Server Error
Sorry, the requested URL 'http://superhost.gr/mailform' caused an error:

Internal Server Error
Exception:
TypeError("argument of type 'NoneType' is not iterable",)
Traceback:
Traceback (most recent call last):
  File "/home/nikos/wsgi/bottle.py", line 996, in _handle

rv = callback(*a, **ka)
  File "/home/nikos/wsgi/www.py", line 189, in mailform
if provider in FROM:
TypeError: argument of type 'NoneType' is not iterable


I somehow beleive that the following apache conf directives somehow create 
problem.

When superhost.gr/test tries to post html form data to the route endpoint 
'/mailform' it sends it to superhost.gr/mailform and NOT at 
superhost.gr/test/mailform as it should have done.

They somehow interfere.

Here is the processes running in the webserver that somehow interfere.

It can (and has been done for ages), just not in the character encoding 
method you've choosen to use.

Putting blanket, unsupported statements forward doesn't score you any 
points.  Feel free to come up with examples* though, as well as (ofcourse) 
how you think it could have been done better

*examples in regard how Python fails to use the character encoding according 
to its definition.   Any complaint towards the encoding itself doesn't 
belong in this newsgroup.

But, seeing that you started this thread with posting stuff that actually 
works**as advertised I won't hold my breath.

**instead of supporting your 'Python makes a mess of it' stance. Which 
ofcourse suggests that that example is actually the worst thing you could 
come up with - but only shows both Python and the UTF-x encodings working as 
expected.

> - This "Flexible string representation" succeded to reintroduced

Nope.   That /you/ don't understand how the UTF-x character encoding works 
doesn't mean others do not either.

Do you know how to take a car engine apart and rebuild it ?No ?   Than 
you also suck at cooking food, am I right ?   (You eat in the car, you 
transport food by it.  The connection is /obviously/ there :-) )

Kiddo, all I have seen you do is to suggest that UTF encoding is bad(1), and 
by association Python is bad(2), by making some reference to other programs 
that do it better(3) and where Python fails(4)

(1),(2),(3),(4) - None of which are underbuild, let alone proven.   In 
short, hollow and meaningless drivel.  Acceptable for a politician, but not 
for a programmer/scripter.

> A real funny mess. Very amusing.

Oh well, you at least get /some/ enjoyment outof knowing* the Python 
language.

* I'm just assuming you are not actually /using/ it, as its so bad and you 
got a range of better languages at your disposal.

But that does make me wonder why you are posting here to start with.

Although, I think I can guess ...

Re: How to POST html data to be handled by a route endpoint

[Νίκος Βέργος]

You will see if you create a route endpoint called 'mailform' within '/' which 
is an alias of 'www.py' and you also have '/mailform' in 'superhost.gr/test' 
when the latter tries to post data to '/mailform' instead of sending them to 
'superhost.gr/test/' it sends them to '/' which is 'superhost.gr'

Yes, that's what I was using.  Turns out I didn't look closely enough at
the exception I was getting.  What i thought was zipfile complaining
about a '/' character was really Python complaining about a bad string
formatting string I was using!

Thanks for confirming that zipfile indeed should work the way I hoped it

b'\xff'.decode('iso-8859-1')
'ÿ'

iso-8859-1 just isn't the DEFAULT character encoding to use.

Re: iterate through an irregular nested list in Python

[Souvik Dutta]

A better way would be to just do
nestedl = [[2], [], [], [l, b, n]]#nested list
for a in nestedl:   #taking all the sublist

  for b in a:   #iterating through the sub
 print(b)

Though it is easy the only limitation is that it works only if the elements are 
lists. Which we can be easily overcome by using an if statement to check the 
elements type.

This is not a place to quarrel our only task is to discuss and help other learn

working on a cryptocurrency project and he might use our original code in his 
final project I don't think offering money is bad. After all there have been 
times when a person demands his name to included in the credits page. Our sole 
task is to help. And you cannot form opinions for other people's by saying them 
not to support a person. That is injustice and rude.

If your lists are nested to inconsistent depth, and you're on a modern version 
of Python (3.3 and up), recursion with yield from (as above) is the way to go.

If your lists are nested to a consistent depth (as your example seems to 
suggest), you can just:

for sublist in aList:
for element in sublist:
yield element

If you need inconsistent depth and you're on an old version of python, yield 
from is unavailable. In that case, it's best to write it out recursively (even 
though that won't work really), and modify that to be nonrecursive using an 
explicit stack or stacks. There's an example of this at: 
http://stromberg.dnsalias.org/svn/treap/trunk/m4_treap.m4
See iterator_macro.
Don't let the m4 throw you - it's just a way of deriving pure python and cython 
from the same file.
You can generate the pure python form the .m4 file with simply: m4 -Dpy=1 < 
m4_treap.m4 > py_treap.py
...if you install an m4 binary.

HTH.

Use a recursive iterator/generator: It becomes a bit peculiar because you want 
special treatment for empty lists inside, but otherwise it is quite standard 
Python:

aList = [[2,'jkj'],[],[],['kite',88,'ooo','pop','push','pull'],['hello']]

def reclist(aList):
for item in aList:
if isinstance(item, list):
if item == []:
yield ''
else:
yield from reclist(item)
else:
yield item

for i in reclist(aList):
print(i, end=',')

This gives you an extra comma at the end, unfortunately. But it is the pattern 
for other types of processing.

Or use it like this:

print (','.join(str(i) for i in reclist(aList)))

How to POST html data to be handled by a route endpoint

On Linux, the most reasonable binary distribution is a .tar.bz2 package which 
extracts a folder with a startup script. This works on every Linux distribution 
and is one of the most common ways for Firefox etc. Of course, if you can 
afford to offer several packages, the other recommended way is packages for the 
system package manager - but this means it is system-dependent - or the newer 
things like flatpak and snap. However the tarball is the thing that always 
works, even for me as a user without root access.

Roads and cars are used by drug dealers. Stop using roads and cars. Cash is

That is fine if you dont like something. You dont have to help me out if you 
dont want to. But trying to censor me is unethical. Hopefully other people will

they choose to do so.

Using zipfile to create a zip file with directories and files inside

[Michael Torrie]

I am trying to do something very simple but having no success in finding out 
how to do it. I just want to use the Python zipfile module to create a zip file 
with a specific directory structure and create and write to files inside those 
subdirectories (not files already on disk).  The documentation talks about 
writing files from disk, but I'm interested in creating these files from within 
Python directly in the zip archive. I've read over the docs several times but 
nothing speaks to this, and none of the examples I've searched for show this 
either.

I thought that in zip files, directories are really just part of the name of 
the file, and if unless you tell unzip not to, it creates them as files are 
extracted. So I naively thought I could use the "open" method of zipfile, 
giving it a relative path describing the relative path and file name that I 
want to then write bytes to.  But seems I am mistaken.  Is this a limitation of 
the zip format that cannot allow that sort of thing?  Must I resort to 
temporary files?

Plenty of examples on how to create an archive from existing files and 
directories on disk of course, which isn't what I want to do.

pip UX Studies - help improve the usability of pip

[Bernard Tyers - Sane UX Design]

Hi there,

My name is Bernard Tyers. I'm a UX designer and have recently started working 
on the PSF project to improve the usability of pip, funded by MOSS/CZI.

I want to let you know about the pip UX Studies we've started today, and 
encourage you to sign-up and take part.

The pip Team is looking for Python users who use pip to take part in our UX 
Studies. Your input will have a direct impact on improving pip.

We want to speak with as diverse a group as possible. We'd particularly like to 
speak with people with accessibility needs.

You _don't_ have to be a Python expert to take part - I can't stress this 
enough!

You can find out all the details you'll need and find the sign-up link on this 
blogpost:

http://www.ei8fdb.org/thoughts/2020/03/pip-ux-study-recruitment/

If you do have questions I've not answered there, let me know.

We'd also appreciate some signal boosting to reach as wide an audience as 
possible. Please share the blog post with people in different Python using 
communities.

If you're a Twitter/Mastodon user we'd appreciate a signal boost of these also:

Thank you for your attention!

Best wishes,

Bernard

But you have seen writestr(), haven't you?

ZipFile.writestr(zinfo_or_arcname, data, compress_type=None, compresslevel=None)

Write a file into the archive. The contents is data, which may be
either a str or a bytes instance;

No your're not. writestr() and ZipInfo are your friends, unless I haven't 
understood what you're trying to do.

I beleive it comes from the web server. Here it is:

Error: 500 Internal Server Error
Sorry, the requested URL 'http://superhost.gr/mailform' caused an error:

Internal Server Error
Exception:
TypeError("argument of type 'NoneType' is not iterable",) Traceback:
Traceback (most recent call last):
  File "/home/nikos/wsgi/bottle.py", line 996, in _handle

rv = callback(*a, **ka)
  File "/home/nikos/wsgi/www.py", line 189, in mailform
if provider in FROM:
TypeError: argument of type 'NoneType' is not iterable


I somehow beleive that the following apache conf directives somehow create 
problem.

When superhost.gr/test tries to post html form data to the route endpoint
'/mailform' it sends it to superhost.gr/mailform and NOT at
superhost.gr/test/mailform as it should have done.

They somehow interfere.

Here is the processes running in the webserver that somehow interfere.


WSGIDaemonProcess test user=nikos group=nikos home=/home/nikos/wsgi
WSGIScriptAlias /test /home/nikos/wsgi/test.py process-group=test
application-group=%{GLOBAL}

WSGIDaemonProcess www user=nikos group=nikos home=/home/nikos/wsgi

Yes, that's what I was using.  Turns out I didn't look closely enough at the 
exception I was getting.  What i thought was zipfile complaining about a '/' 
character was really Python complaining about a bad string formatting string I 
was using!

Thanks for confirming that zipfile indeed should work the way I hoped it wood. 
I'm in business now.

thank you.

Re: How to POST html data to be handled by a route endpoint

[Νίκος Βέργος]

You will see if you create a route endpoint called 'mailform' within '/' which 
is an alias of 'www.py' and you also have '/mailform' in 'superhost.gr/test' 
when the latter tries to post data to '/mailform' instead of sending them to
'superhost.gr/test/' it sends them to '/' which is 'superhost.gr'

The HTML path /mailform means server relative path, so the path is
relative to the SERVER, not the current page, so it would be
superhost.gr/mailform

The other format goes through a function which might re-interpret the
path and either make it page relative or add in the path of the current
page to get to /test/mailform
