Python is a widely used general-purpose, high-level programming language. Its design philosophy emphasizes code readability, and its syntax allows programmers to express concepts in fewer lines of code than would be possible in other languages. Python supports multiple programming paradigms, including object-oriented, imperative and functional programming or procedural styles. It features a dynamic type system and automatic memory management and has a large and comprehensive set of standard libraries, including NumPy, SciPy, Django, PyQuery, and PyLibrary.

USB GPS Detection on Raspberry PI

I have some python code that scans WIFI packets and in my receiver code I have an instance of a GPSPoller class.

The issue I am having is that withing the gps library blocks when there is no GPS dongle connected to the Pi.

I couldn't seem to find an elegant way to check to see if gpds has any devices added to its device pool so I could skip my code that starts polling gpsd for position data.

I don't want to write code to check for /dev/ttyUSB0 as that does not seem like a very elegant solution.

Can anyone provide advice?

lsusb would list my device but then I would have to write software that looks for the specific device. If I swapped out the receiver for a different kind I would have to change the code to take that into account.

I hope there is a better way to do it that lsusb.

by:Mark Wieder
Yeah, if you want the code to be more generic (how often do you intend to swap out a different gps dongle?) then lsusb probably won't help here. You might try setting up a socket connection to port 2947 and trap the error, but you'll have to do this before instantiating the gps class because the class initializer does that as well.
pip install twilio
works perfectly on a Pi2.   Just bought a new Pi3 with the latest NOOB.  
same version of python (2.7.9), same version of pip (1.5.6).  I keep getting the error:

TypeError: __str__ returned non-string (type Error)

Googling around, I checked and verified that
- no network issue, Chromium connects to
- my date/time on the computer is correct
- some talk about --trusted-host= but that parameter is not valid on pip
- some talk about creating an /etc/pip.conf file and adding but that makes no difference (assuming pip every reads that file...)

My guess is that it has something to do with the SSL certificates... but I have no idea how to solve it.  
sudo apt-get install libssl-dev did not help

Hi: Don't you just hate banks?
We have changed bank and I download all the data  for analysis.  Our new bank offers only csv format. No problem...EXCEPT that for direct debits and standing orders the text field has a comma inserted! It looks to me that the comma is inserted just prior to the word MANDATE.
Dopes anybody know how to write something in python that deletes (or replaces with a semi colon) a comma that appears just before the word MANDATE in a csv file?
Here is a snippet of the text field:
See that stupid comma in the middle?
The text before the comma changes every time.

For a school project, I've been tasked with setting up an attendance-taking program. I've done some research and have come to a conclusion: I need some help.

I've got a bit of a plan but I'm not sure if it will work since I've got next to no experience in this type of thing. I want to use a barcode scanner to scan a specific barcode for a student and then input that into some sort of python program and log attendance.

I'm confident I can write the python code but I don't know how to connect a barcode scanner to the IDE, I'm also not sure which IDE to use.  I have considered trying to use Arduino connected to a webcam (or something similar).

Nevertheless, I need some expert advice, so any input will be met with extreme gratitude since I've been stuck at this point for weeks.
Thanks in advance.

I have a OID as below

I would like to know how can I convert it to it's name using python? I do not want to make any network or localhost call.

this OID is mapped to one of the VSERVER's Name in NetScaler.
So long story short I think it MAY have something to do with my shebang in my python. I know on our server we have a few different versions of Python and I installed my modules (paramiko and pysftp) in the correct place I believe. Honestly I have researched and am having trouble understanding how exactly the shebang works and knowing what interpreter it is pulling from or why the cron job is failing for that script (is there a log file perhaps to help determine the cause?)

Cron listing:
* * * * * /usr/local/ > /dev/null 2>&1
(Yes for testing purposes I am trying to have it run every minute just to see if it runs)

import os
import pysftp
import os.path
import paramiko


srv = pysftp.Connection(host=HOST, username=USER, password=PASSWORD)

def do_nothing(fname):
        return  " "

def fetch_and_remove(fname):
    if not fname.endswith(SUFFIX_TO_FETCH__AND_DELETE):
        return # skip files with wrong suffix
    dst_fname = os.path.join(DESTINATION_PATH, fname)
    dst_dirname = os.path.dirname(dst_fname)
    if os.path.isfile(dst_fname):
        return " "
        srv.get(fname, dst_fname)

srv.walktree('.', fetch_and_remove, do_nothing, do_nothing)


Open in new window

For the record, running this script from the commando line works instantly and perfectly. But when trying to automate it through the cron I have no luck.

Any help trying to understand which interpreter my cron is trying to use and the location of such would be greatly appreciated.
Hi all!

I wrote a little python code to continously check if the user is active and, if not, lock the computer screen.

This works well.

I've then decided to use a small systray icon to enable / disable the endless loop that is checking for user activity but it seems like showing the systray icon is an endless loop itself.

Therefore if I run my current code:

# Instructions
# Pair your phone to your pc's bluetooth as first step
# Then scroll down and customize the locker's parameters before running
# the script. Simply search for "Customize me" to make your life easier :)
# 1st parameter is your phone name (in my case 'G4') and 2nd is maximum
# number of seconds that the user is not active before the screen
# is autolocked

# Importing classes
from autolocker_class import *
from systray_icon_class import *

# Customize me!
locker = ScreenLock('G4', 10)

# Minimal self test. You'll need a bunch of ICO files in the current working
# directory in order for this to work...
if __name__ == '__main__':
    hover_text = "IPAutolocker"
    bluetooth_icon = 'Checked.ico'
    def autolocker_on(sysTrayIcon):
        locker.is_autolocker_enabled = True
        print "Autolocker enabled"
    def autolocker_off(sysTrayIcon):
        locker.is_autolocker_enabled = False
        print "Autolocker disabled"
    def bluetooth_on(sysTrayIcon):
        is_bluetooth_on = True
        print "Bluetooth enabled"
    def bluetooth_off(sysTrayIcon):
        is_bluetooth_on =

Hello Python Individuals,

I need to connect to the Lotus Notes and do some operations (Send/Receive mail with Attachments).
However, I am not able to get past even the ‘Dispatch’ step:

I am expected to propose the EDIFACT solution for a company that starts from scratch (regarding EDIFACT).

Communication via OFTP2 ready to be used (on Linux)

The only thing that is already decided and ready to be used is the OFTP2 communication (on Linux machine, OS4X by c-works if it matters, ODETTE ID assigned).

This way, message splitting or even parsing can use UNIX-based tools. Anyway...

MS SQL and procession on Microsoft Server

... the original message (before parsing) will also be saved on Microsoft based server (as a blob in the SQL table).

The database and the Enterprise applications is running on a different computer -- Microsoft Windows Server, MS SQL Server.

First messages to be processed

The Delivery schedule message (DELFOR) and Despatch advice message (DESADV) are the first one to be received. I am aware of versions of the EDIFACT messages (about two releases each year).

I am aware of X12 being the predecessor of EDIFACT, of the other standards like Tradacom, VDA, ... and the consequences of having tools for transformation of the messages. However, the decision was made to use the pure UN/EDIFACT only.

Differences based on a partner decisions

I am partly aware of (future) problems with _the same kind of message from a different …

I want to import a huge number of very small text files (content is 1 line per file) parse the line and convert it to another text file using delphi. Using the simplest assign(f) etc approach will take several weeks to execute. The bottleneck might probably be the opening/closing of each file. Is there any other way of doing this a lot faster?  maybe using another scripting language? which one?
