On behalf of the Python development team, I'm very happy to announce
the release of Python 3.3.5.

Python 3.3.5 includes fixes for these important issues:

* a 3.3.4 regression in zipimport (see http://bugs.python.org/issue20621)

newlines (see http://bugs.python.org/issue20731)
* potential DOS using compression codecs in bytes.decode() (see
http://bugs.python.org/issue19619 and http://bugs.python.org/issue20404)

and also fixes quite a few other bugs.

Python 3.3 includes a range of improvements of the 3.x series, as well
as easier porting between 2.x and 3.x. In total, almost 500 API items
are new or improved in Python 3.3. For a more extensive list of
changes in the 3.3 series, see

I did some work in c# and java and I converted some application to Python; I noticed Python is much slower than the other languages.

Is this normal ?

Re: Top down Python topic

I've realised that the best way to do this is to use a web browser for
the graphical front end: high end graphics are simply not a necessity
here, so one does not need to leave the confines of the browser. Thus
we need a simple server script.

I'm still minimalist, so I guess we want xmlrpc and a python server,
with a bit of javascript in the browser to sort out the drawing end.
This now seems way simpler than trying to play with Gtk or Qt.

Basically the lesson is to use a web browser engine as a graphics engine
unless you have performance issues. Hopefully in future html rendering
engines will not be so strongly coupled to browsers, or even to the html
format itself, but will be a general purpose user graphics engine (an
ncurses for bitmapped displays).

Can anybody suggest the quickest way to learn the bits of xmlrpc (in
python) that I need to do this. Once it's working, I'll stick a source
code download on my website. There will be only one version released:
the one that works properly. Thus there is no need to github this.

All the best,

Send commands to USB device in Python topic

Hi fellows,
I am facing difficulties in order to send USB commands to an RFID reader.
This is the command reference of the device: https://github.com/mti-rfid/RFID_Explorer

I am working with the MTI RU-824 model.

The manufacturer of the device only provide a driver for Windows (using .Net), but we need to run the device on Linux. That's why I need to write few lines of code in Python as a new "driver".

I am using PyUSB for accessing the device, and this is few lines of my code:

================================================== ==========================

import usb.core
import usb.util
import sys

VENDOR_ID = 0x24e9
PRODUCT_ID = 0x0824

device = usb.core.find(idVendor=VENDOR_ID, idProduct=PRODUCT_ID)

if device is None:
sys.exit("Could not find Id System Barcode Reader.")
else:
print 'Device detected'

device.set_configuration()

cfg = device.get_active_configuration()
interface_number = cfg[(0, 0)].bInterfaceNumber
alternate_setting = usb.control.get_interface(device, interface_number)
usb_interface = usb.util.find_descriptor(
cfg, bInterfaceNumber=interface_number,
bAlternateSetting=alternate_setting
)

endpoint_out = usb.util.find_descriptor(
usb_interface,
# match the first OUT endpoint
custom_match=lambda e: usb.util.endpoint_direction(e.bEndpointAddress) == usb.util.ENDPOINT_OUT
)

endpoint_in = usb.util.find_descriptor(
usb_interface,
# match the first IN endpoint
custom_match=lambda e: usb.util.endpoint_direction(e.bEndpointAddress) == usb.util.ENDPOINT_IN
)

endpoint_out.write('0x01')
print endpoint_in.read(len('0x01'), 1000)

================================================== ===========================
My question is on the last 2 lines.
I am using endpoint_out to send a command and endpoint_in to read data from the reader. Am I correct?

The problem is, when I run the code, there is an error message like this:
usb.core.USBError: [Errno 110] Operation timed out

Anyone can give a clue?
Thank you.

Thanks for being up-front about it being homework. I'll give you one
broad hint, and see if you can figure it out from there.

Your beginning work is not actually achieving anything useful. To make
your next steps work, what you actually want is two very simple
assignments that will mean that "6 * hours" comes out as the number of
seconds in six hours. Then, when you've added all the different pieces
together, you'll have a final time that's measured in seconds - and
since that final time includes the time_left_house, it's actually
going to be the number of seconds since midnight. This is actually an
excellent way to represent time (number of seconds since some
"beginning point" aka epoch). There's then just one last step: Convert
it into hours, minutes, and seconds, for display. You have most of the
code for doing that.

So, work on this in two parts. In the first part, make your program
calculate how many seconds after midnight you'll get home. (The
correct answer there is 27006, according to my calculations. Of
course, you need to have a program that produces the correct answer,
not just the answer.) Then work out how to make that display as
hh:mm:ss.

I think you can probably get it from there - you're already a lot of
the way toward it. But if not, you know where to find us :)

One entry is 'IDLE (Python GUI)'. I have never seen Idle referred to as
'Python GUI' as the later is non-specific and could refer to wxpython or
pyqt or some other Python GUI.

Idle open a window called Python x.y.z Shell (until recently just Shell).

The other menu entry is 'Python (Command line)' and I am guessing that
the paragraph above has nothing to do with this entry.

Try the following, which I believe I said before.

1. Start the normal console interpreter 'Python (command interpreter)'
in the Start Menu.
2. In the interpreter, type
>>> import idlelib.idle
3. Open a file. If Idle quits,
4. If Idle quits, look in the console for an exception message.
5. If you do not understand it, *copy and paste the entire message* here.
6. If the Python console also closes, report here.

This much I understood.

This I do not. What is 'Python GUI'? What is 'Python Shell'?

As Steven's pointed out, this looks more like a Windows permissions
issue. However, it would still be worth identifying what's going on, as
I haven't run Python on a 2012 box (and I doubt if many other people
have either). I'm getting a VM run up to try it out but that will take a
while.

It may be that some hardened security is preventing Python from reading
its own files. Could you, please, do the simplest of imports which
fails, and post the traceback from the console in its entirety? (In
other words, something like this):

"""
Python 3.3.3 (v3.3.3:c3896275c0f6, Nov 18 2013, 21:18:40) [MSC v.1600 32
bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import willnotimport
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'willnotimport'
>>>
"""

It would be good to know whether *anything* imports, ie whether stdlib
imports work, or whether it's just user-installed modules.

This does not appear to be a Python problem. This appears to be a generic
Windows permissions problem. My guess is that you've made sure that the
Python .exe is executable by all users, but the standard library files
are only readable by the Administrator user.
