Sounds great, Cameron. But Gmail doesn't give me the options "Apply the label 
Python" and "Skip the inbox" under "Filter messages like this." I just get the

Thanks you a lot for all your tips ! They helps me a lot :) 
I'm beginner in python, this is an excercise I'm trying to realise.

I gonna read more about exceptions and .splitex() !

I work with a file which contains millions lines, a simply file.read() and I'm 
running out of memory

Wait for the first message or so and for that message choose GMail's "filter

in your collection where the list will accumulate. And less spam than the

Sounds great, Cameron. But Gmail doesn't give me the options "Apply the label 
Python" and "Skip the inbox" under "Filter messages like this." I just get the 
generic To, From, Has the words, Doesn't have.


The first panel with to/from etc is just the message selection panel. It 
probably has the "includes the words" field already filled in with something 
that will match a python-list message. When you click "Create filter with this 
search" you get another panel with what to do with matching messages.


I usually:

- skip the Inbox
- apply the label: click the "Choose label" dropdown and create a new label 
 "python" or whatever suits you
- also apply filter to matching conversations, which will gather up all the 
 list messages that have already arrived and filter them, too


Also note that you don't need a label per list. I file a few mailing lists in 
the same "python" folder.


Alternatively, you might make a label per list; note that you can put a slash 
in a label eg "python/python-list" and GMail will treat that as a hierarchy, 
making a "python" category on the left with "python-list" underneath it. Might 
be handy of you join several lists and want to group them.

Assuming each line is on average a hundred characters long, a million 
lines is (approximately) 100 MB. Even on a computer with only 2GB of 
memory, you should be able to read 100 MB.

But you shouldn't: it is much better to process the file line by line.


# Don't do this:
with open(pathname) as f:
text = f.read()  # Slurp the entire file into memory at once.
...

# Do this instead
with open(pathname) as f:
for line in f:
# process one line at a time


You said you are running out of memory, earlier you said the computer was 
crashing... please describe exactly what happens. If you get a Traceback, 
copy and paste the entire message.

(Not just the last line.)

I resolve my problem and when I look to my solution I don't understand why I 
didn't do it earlier :)


with open(path) as file:
  result = []
  for line in file:
find_regex  = re.search(regex,line)
if find_regex:
  result.append(find_regex.group())
  if len(result) == 0:
sys.exit('Regex not found')
  elif result[0] == '':
sys.exit('Whitespace as regex don\'t work')


I was looking for a way to check if the regex's user was correct or not

But the "50% discount" is supposedly good up until the release date.  
I could purchase the software the day before release and still enjoy

I understand the advantages *to the company*, but to enjoy those

I don't see one here.  Anyway, I was just curious to see if there was 
any kind of thought process behind the "promotion".

Thought process?

I believe the current strategy I have in mind is to let any potential 
new customers to take the time needed to consider seriously 
Django-hotsauce for their commercial web applications.


This includes allowing some time for peoples (developers) to at least 
try the free version and then possibly consider switching to the LTS 
version for extended support and troubleshooting.

Ooops...  I didn't notice the 'python 2.7' part until after I had coded up
something.  This solution could probably be squeezed to work with Python 2
somehow, though

I am actually a perl guy, and I love regex... in perl.  I do tend to avoid
it if all possible in Python, though.  I pieced together an ugly function
to do what you want.  It avoids naming the arguments, so if a new argument
is added to your records, it should handle it with no changes.  In python,
I love comprehensions almost as much as I love regex in perl.

Anyway, here is my n00bish stab at it:

#!/usr/bin/python3

line = '06/12/2018 11:13:23 AM python toolname.py  --struct=data_block
--log_file=/var/1000111/test18.log --addr=None --loc=0 --mirror=10
--path=/tmp/data_block.txt size=8'

def get_args(lne):

first_hyphens = lne.find('--')# find where the args start
if first_hyphens == -1:# Blow up if ill-formed arg
raise ValueError("Invalid input line")
prelude = lne[0:first_hyphens]  # Get the stuff before the args
prelude = prelude.strip()
args = lne[first_hyphens:]  # Get the arguments
#  The following line uses comprehensions to build a dictionary of
#  argument/value pairs.  The arguments portion is split on whitespace,
#  then each --XX=YY pair is split by '=' into a two element list,  Each
#  two element list then provides the key and value for each argument.
#  Note the 'd[0][2:]' strips the '--' from the front of the argument
#  name
argdict = {d[0][2:]:d[1] for d in [e.split('=')[0:2] for e in
args.split()]}
return (prelude, argdict)

if __name__ == "__main__":
pre, argdict = get_args(line)
print('Prelude is "{}"'.format(pre))
for arg in argdict:
print('  Argument {} = {}'.format(arg, argdict[arg]))

Hey Friedrich,

Only thing I think would need a review is   if the assignment of the value
of one dictionary to the another dictionary  if is done correctly ( lines
17 to 25 in the below code)


Here is my code :

root@X1:/Play_ground/SPECIAL_TYPES/REGEX# vim Friedrich.py
   1 import re
   2 from collections import OrderedDict
   3
   4 keys = ["struct", "loc", "size", "mirror",
   5 "filename","final_results"]
   6
   7 stats =  OrderedDict.fromkeys(keys)
   8
   9
  10 line = '06/12/2018 11:13:23 AM python toolname.py  --struct=data_block
--log_file=/var/1000111/test18.log --addr=None --loc=0 --mirror=10
--path=/tmp/data_block.txt --size=8'
  11
  12 regex = re.compile (r"--(struct|loc|size|mirror|
log_file)\s*=\s*([^\s]+)")
  13 result = dict(re.findall(regex, line))
  14 print result
  15
  16 if result['log_file']:
  17stats['filename'] = result['log_file']
  18 if result['struct']:
  19stats['struct'] = result['struct']
  20 if result['size']:
  21stats['size'] = result['size']
  22 if result['loc']:
  23stats['loc'] = result['loc']
  24 if result['mirror']:
  25stats['mirror'] = result['mirror']
  26
  27 print stats
  28
Looks okay to me. If you'd read 'result' using 'get' you wouldn't need 
to test for the key. 'stats' would then have all keys and value None for 
keys missing in 'result':


stats['filename'] = result.get ('log_file')
stats['struct']   = result.get ('struct')

This may or may not suit your purpose.


Also, I think  the regex can just be
(r"--(struct|loc|size|mirror|log_file)=([^\s]+)")
no need to match white space character (\s* )  before and after the =
symbol because this would never happen ( this line is actually a key=value
pair of a dictionary getting logged)

You are right. I thought your sample line had a space in one of the 
groups and didn't reread to verify, letting the false impression take 
hold. Sorry about that.

Flask failure

Python list vs google group

[T Berger]

I'm suspecting that posting to python google groups (this site) gets more 
responses than mailing to the python list. Am I correct? Also, contrary to what 
I read on the python list information sheet, what shows up in this forum does 
not match what comes into my inbox. I started a post here and then replied to a 
post from my inbox. That reply does not show up in this forum.

it certainly seems to be the source of most SPAM
as such some users of this list/newsgroup call it what you like block all 
posts from google groups

But you don't think you get more replies to a question posted here than emailed 
to the list? The forum and the email list are supposed to be different access 
routes to the same content, but I don't find that to be the case. I replied to 
a post via email, but my reply did not show up on this forum.

Is "more replies" your best criterion? I posted something to a much
smaller mailing list and got several HUNDRED replies. In fact, that's
happened to me multiple times, with multiple different lists. Perhaps
quantity is not the important thing here.

Tamara,

  That's not been my experiences. I subscribe to a few mail lists that are
mirrored on googlegroups.com. My preference is to have messages pushed to me
by the mail list manager rather than my using the browser to go to
googlegroups and pull threads. YMMV.

  Anyway, I've not had any threads, including ones I start, not appear in my
mail reader. I've not had a response posted to google groups that did not
also appear in my mailbox. Perhaps your experience has something to do with
your MUA.

Regards,

Rich

For the third and final time, just get a (semi-)decent email client/news

forum, hundreds of other python forums and thousands of other technical

To do this, I will have to research what you mean by "a (semi-)decent email 
client/news reader," and "point it at news.gmane.org." I'm a little unused to 
web-related lingo. Then I'll have to root around in gmane.org to see how it 
works. This is not to say that I might not try this route, only that it will 
take a bit of time and effort. I just set some filters on the incoming python

  Nope. Most of us do not reply if we have insufficient knowledge to offer a
usable response. Saves bandwidth and electrons. When you get no replies it
usually indicates no one knows how to help. Happens quite a bit.

Did the instructions for running this Flask example mention anything about not 
using the standard HTTP port number (80)?  I don’t know much about Flask but I 
expect it runs an HTTP server in order to serve your HTML content to clients. 
If it tries to use the standard port then it will likely find it is already in 
use or that you do not have permission to use it.

I regret that this might seem less than helpful, but someone
should point out that an enumeration beginning "This package
works with the following data types" would be antithetical to
Python's "duck-typing" philosophy.  The important thing is not
an object's type, but whether the object has the attributes and

I once had a Mustek color scanner that came with a TWAIN driver.  If the

I know what it is to have a complete apparatus for conducting the
circulation of blood through the veins and arteries of the human body.

But I have not a heart that up and gives me quarter-deck orders that
it is life-and-death to disobey. I have not a heart of that
description, nor a picture gallery that presumes to take that liberty.

I would be mind-blown if I did not have the aforementioned too many
hours. Sadly, I am merely facepalming. Wow.

There actually may still have been a hardware issue, likely something
marginal in the timing on the cable. (Timing changing with temperature).
It would take a detailed look, and a fine reading of specs, to see if
the Windows Driver was to spec, and the hardware is marginal (but the
Linux driver didn't push the unit to full speed and got around the
issue), of if the Windows driver broke some specification but still sort
of worked, especially if things were warm, while the Linux driver did it
right.

Actually it does show up. The problem is that Gmail silently throws away
your own post when it gets emailed back to you by the listserv.  But
your messages still get through to the list.  The only way I've figure
out to get around this bug in Gmail is to post from a different SMTP
server than the normal GMail one.  But most people don't have a
different SMTP server to use, and also there are issues with DKIM and
other supposed anti-spam features.

I once had a Mustek color scanner that came with a TWAIN driver.  If
the room temperature was above 80 degrees F, it would scan in color -
otherwise, only black & white.  I was *sure* it was a hardware
problem, but then someone released a native Linux driver for the
scanner.  When I moved the scanner to my Linux box, it worked fine
regardless of temperature.

You are exactly right.  It was so long ago that I forgot some of the 
details, but it boiled down to the TWAIN driver pushing the SCSI bus out 
of spec.   I remember looking at the bus on a scope, measuring pulse 
widths, and playing with terminator values to try to optimize rise 
times.  I don't believe it used the Windows SCSI driver at all, but 
instead drove the scanner directly (I could be remembering wrong).

Server warning

[Tamara Berger]

I created a webapp with flask, but got a warning in terminal when I tested it.

Last login: Sat Jun 16 01:13:28 on ttys000
192:~ TamaraB$ cd Desktop/Webapp
192:Webapp TamaraB$ python3 hello_flask.py
 * Serving Flask app "hello_flask" (lazy loading)
 * Environment: production
   WARNING: Do not use the development server in a production environment.
   Use a production WSGI server instead.
 * Debug mode: off
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

Is this a serious issue, or can I ignore it? I was just following
instructions in a manual I consider trustworthy.

Thanks,

Tamara

(A word of advice: You have recently been asking here for many different
topics – Flask, Google Mail, etc. – that are not the focus of this
forum. That's not a problem for us, but you would be better to seek
specific help for those topics at their specific support forums.

This is not any kind of support forum, it is a discussion forum for the
Python community. You're part of that now, so welcome! But this is not a
forum for getting support when you're needing help.)


The message from Flask is, I believe, both serious *and* you may be able
to ignore it.

If you are not intending to make the server available on the internet,
you are free to ignore it for that case.

You should never expose the development server onto the live internet.
Use a proper WSGI server (its own topic, with more involved steps)
instead.

The development server is much easier to start (which is why it's there,
and why it is recommended when learning), but much less secure (which is
why, before deploying your application, you need to configure a
properly secure WSGI server).
