Re: Good editor for python
Hi Olivier
I am glad you did not trigger an editor war. I don't know how familiar you are
with emacs. The answer depends alot on your preference and future work. Emacs
and vi have been around for a long time for good reasons.
If you prefer an extensible and futureproof editor, I can wholeheartedly
recommend emacs or vi. I went from a happy emacs user to an even happier
spacemacs user. Spacemacs is a batteries-included emacs configuration which
lets you choose between emacs-like or vi keybindings, which are mnemonic,
efficient, consistent, and, above all, discoverable. Discoverability allows a
person who has been using something for a while to find out even more tricks
in the moment that those tricks would be useful. Spacemacs has tons of bells
and whistles and still manages to be fast (through lazy configuration
loading).
If you are looking at literate programming, Jupyter Notebooks are hard to
beat, especially if you want to share code with novices. In case you want a
medusa that eats everything else for lunch, look further. Such a beast can be
harnessed with org-mode, an emacs mode which can be just about anything you
want it to be. You can do literate devops, literate programming, mix
programming languages, export to your grandma's toaster, and feed the dog with
org-mode, if you want to play. Org-mode's syntax and power is unmatched, to my
knowledge.
That all depends on how far down the rabbit hole you want to dive. Emacs with
pdb is pretty good though. To get the functionality you miss is pretty simple
with spacemacs. For more information and platform-specific instructions,
please see the following link.

The basic template already activates python support.
That's my two cents.
Cheers
Brian

Supposedly there are also some security concerns. The mail server does some pretty good filtering already. I made the mistake of being vague about the problem. Let me specify. - General Problem: too many emails to answer with due care - Technical Problem 1: can't be run on mail server. - Technical Problem 2: answers needed in 2 and possibly 4 languages. - Future Problem 3: don't have resources to maintain the solution forever - Future Problem 4: software may be running in many different countries with different languages and legal frameworks. - Goal: lighten the load - Potential: many emails pose questions to information already on the website. - Potential solution: automate personalized replies with relevant information. Nonetheless, barring a tip to an existing solution, I will be rolling my own. Off the top of my head, I image the setup being eerily similar to a flask website. I would rely on smtplib, imaplib, nltk, pyzmail, and jinja2. Draft Algorithm: 1. read mail 2. tokenize body's contents 3. apply logic to determine answer 4. render appropriate answer template 5. send email 6. refile email maildog/ app.py answer_logic/ english.csv german.csv french.csv maildog/ __init__.py send_mail.py read_mail.py refile_mail.py decide_answer.py templates/ base.html base.txt info.html info.txt schedule.html schedule.txt tests/ test_answer_common_email.py test_explain_upcoming_schedule.py test_read_email.py Somehow I think someone smarter already solved this niche case. A part of me wants to delve into OpenEMM. The rest wants to write code. Now that it seems that I will be writing this. What is the recommended way to set up a timer. I know 2 system options, systemd timers and cron jobs. I prefer the former for the handy logging options. What about a python solution? What would the advantage of a python queue be over a systemd timer? I guess that's an apples an oranges comparison. In my case I most likely would have a raspberry pi running a python script to read and possibly answer any emails. Thanks again for the tips.

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)})

Re: Python Templating Language
I am not exactly sure what you mean, so I will guess. Jinja may be what you're looking for. It's an important component of flask & ansible, for example. pyweave may also serve your purposes. HTH -- https://mail.python.org/mailman/listinfo/python-list
advice for inventory software
Dear Python scripters, I am writing modules for my insectary (for food), the processes of which I plan to mostly automate. Currently, inventory and the traceability of material flows is my focus. My best idea (yet) for making things as simple as possible consists of a debian server hooked up to a barcode scanner. The input of information would consist of scanning barcode sequences (Start process, item1, ..., stop process). For this, I plan to implement a listener to the usb port, which takes the input and knows what to do with it. Later on, there will be multiple simultaneous input sources. For now, I imagine a simple flask app capturing the input and feeding it into an SQL database. Certainly, someone has had the opportunity to something similar if not identical. I would be particularly greatful for advice on design and work already done. For those interested, I have my progress on github.com/oneyb. I almost done with the basic inventory barcode printing functionality I need. You may think I am reinventing the wheel. If so, why would I ask for advice? Also, the highly closed nature of the insect breeding business, my slim budget, and the desire to easy extend functionality in the near future (plus a mild case of 'I wanna code' [aka NIH] syndrome), push me to learn and implement this myself. Thanks in advance! Cheers Brian -- https://mail.python.org/mailman/listinfo/python-list
