That *is* Python 3 syntax. It is also accepted under recent releases
of Python 2.
120917 Marc Joliet wrote:
print(' ',eval(expression))
That does the calculation, but the output is wrongly formatted :
514 bin pycalc1 2+3
(' ', 5)
This is because Marc's code is syntactically invalid for Python 3. It
is acceptable to Python 2, but does not do what you want; but it won't
work at all under Python 3.
No, he simply executed it using python2, hence he printed a tuple. My version
certainly prints the exact same output as the python2 version, *when executed
by python3*. You tried it out first, right? I certainly did.
Note that the only difference to your version is that yours does string
formatting via str.format(), which also exists in Python 2. That of course has
the advantage of working the same in Python 2 and 3 (*if* you care about that):
the argument to print is not a tuple anymore, so it is not formatted as such:
$ python3 -c print('{0}'.format(3))
3
$ python2 -c print('{0}'.format(3))
3
It is clear that you have not taken my advice to use the -3 run-time
option in your hash-bang line. At the risk of blowing my own trumpet,
that was *extremely sound* advice; you should really take it. It would
have revealed the problems with the above code during the Python
interpreter's initial scan of the code. I'll repeat it:
!#/usr/bin/python2 -3
This will perform a Python 3 syntax check, even under Python 2. It
will identify any going-forward issues for your Python script(s).
I also just remembered the 2to3 program, which will translate trivial (such
as print vs. print()) and (I think) some not so trivial cases to python3 syntax
for you. Personally I think you should just convert your scripts to python3 and
be done with it, unless you want to avoid python3 forever.
Of course, Philip did say this is his only python script, so using python2 -3
might actually be a tad overkill for his purposes, unless he wants to start
learning python, in which case: why not just start with python 3?

[gentoo-user] MTP auto-mount? (Kindle Fire HD)
Hi all,
Are there any known tricks for auto-mounting an MTP device? I think
this stuff is used on some newer Android phone so I'm hoping someone
has a nice solution.
My wife decided to buy the new Kindle Fire HD based on our good
experience with the original Kindle Fire. The new device is very nice
- faster, nicer screen, better networking, etc. - but no longer
presents itself as a USB Mass Storage device like my older Kindle
Fire. Rather it uses Media Transfer Protocol. (MTP) I've managed to
get it mounted using a package from the poly-c overlay called jmtpfs.
Info is located here:
http://research.jacquette.com/jmtpfs-exchanging-files-between-android-devices-and-linux/
I've copied some movies over and they play fine on the new device
but it's all by-hand manual mounting, etc. When the device is plugged
in I get this sort of info in dmesg:
[15720.370654] usb 2-2: new high-speed USB device number 4 using ehci_hcd
[15720.490935] usb 2-2: New USB device found, idVendor=1949, idProduct=0007
[15720.490940] usb 2-2: New USB device strings: Mfr=2, Product=3, SerialNumber=4
[15720.490944] usb 2-2: Product: Kindle
[15720.490947] usb 2-2: Manufacturer: Amazon
[15720.490949] usb 2-2: SerialNumber: REMOVED
and based on one post I read for Ubuntu (or maybe Arch - I don't
remember) I've created this udev rule:
mark@c2stable ~ $ cat /etc/udev/rules.d/51-android.rules
UBSYSTEM==usb, ATTR{idVendor}==1949, ATTR{idProduct}==0007, MODE=0666
mark@c2stable ~ $
Anyway, it's all usable but a bit clumsy. Is there a sensible way I
can have the device recognized and mounted via rules in fstab? (Or any
other fixed file?)
Thanks,
Mark

[gentoo-user] new machine : mail out, but not in
The rest of my new box is working, but -- as expected -- mail isn't. I can send mail, which is recorded in syslog arrives at this machine, but I can't grab mail from the 2 mail servers out there (ISP + UoT). The cron job in /var/spool/cron/crontabs is the same as here with the same permissions syslog says it runs it every 5 min . .fetchmailrc is the same there as here so is .procmailrc . I've tried remerging Fetchmail Procmail their deps checked USE flags. There definitely was mail to download, as the test msgs I sent had been waiting some time when I got them on this machine (yes, I always send 2 of them via each of the mail servers). One thought is that it mb due to the presence of Python3 on the new machine: there's a line at the end of the Fetchmail emerge output which says something re CPython. Mail is usually difficult to get going, as there are so many pieces they all have to work correctly. Any suggestions are very welcome. -- ,, SUPPORT ___//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT`-O--O---' purslowatchassdotutorontodotca

If mounting once and transferring 4GB of data in 6 files, unmounting
and then playing 5 minutes of video quaifies as reliable then yep,
it's reliable. ;-)
All I can say at this point is it seemed to work the way it was
advertised on the link in the first post. I'll post back over time as
I learn more. Possibly you an others who run into similar usage models
will too.

I used to run folding but only in the winter time. I don't mind the heat during the winter since I have electric heat anyway. It doesn't matter if the heat comes from the puter or from the regular heater, it's still heat from the power company. I may as well give back a little when I can. Thing is, I have had issues with folding and have not run it in a while. I started the service but they had no units for me to download and work on. So, when spring came along, I stopped it. I don't think it ever had a single unit all last winter. I chose folding because I have health issues myself. It may not help me but it may help someone else. Maybe someone else will do something to help folks like me. :/ I unhook things that I don't use often or rarely. I have a large air compressor that I turn off unless I plan to use it right away. I even have a small tank for little things, like putting air in the wheel barrow or something like that. I try to conserve on the things that are not used often but don't on the things that I use a lot. I would never think of cutting off my fridge or deep freezers just to save on energy. If my food spoils, that would cost me more than I save. If I had a light bulb that took a minute to come on, I'd likely leave it on a lot if I use it a lot. Why, I don't want to have to wait for it every time I need it. If it costs that much to run, time for a better bulb or something. 96 watts for standby is excessive for sure.

Hi all,
Are there any known tricks for auto-mounting an MTP device? I think
this stuff is used on some newer Android phone so I'm hoping someone
has a nice solution.
MTP is used on a quite a few newer Android devices, including my Nexus
7. I haven't found an automount solution yet, but it is possible to
create an fstab entry, though
My wife decided to buy the new Kindle Fire HD based on our good
experience with the original Kindle Fire. The new device is very nice
- faster, nicer screen, better networking, etc. - but no longer
presents itself as a USB Mass Storage device like my older Kindle
Fire. Rather it uses Media Transfer Protocol. (MTP) I've managed to
get it mounted using a package from the poly-c overlay called jmtpfs.
Info is located here:
http://research.jacquette.com/jmtpfs-exchanging-files-between-android-devices-and-linux/
I've copied some movies over and they play fine on the new device
but it's all by-hand manual mounting, etc. When the device is plugged
in I get this sort of info in dmesg:
[15720.370654] usb 2-2: new high-speed USB device number 4 using ehci_hcd
[15720.490935] usb 2-2: New USB device found, idVendor=1949, idProduct=0007
[15720.490940] usb 2-2: New USB device strings: Mfr=2, Product=3,
SerialNumber=4
[15720.490944] usb 2-2: Product: Kindle
[15720.490947] usb 2-2: Manufacturer: Amazon
[15720.490949] usb 2-2: SerialNumber: REMOVED
and based on one post I read for Ubuntu (or maybe Arch - I don't
remember) I've created this udev rule:
mark@c2stable ~ $ cat /etc/udev/rules.d/51-android.rules
UBSYSTEM==usb, ATTR{idVendor}==1949, ATTR{idProduct}==0007, MODE=0666
mark@c2stable ~ $
I documented what I had to do to mount my Nexus 7 on the forums, under
my own Nexus 7 thread, although now that I think about it, I don't think
I put an fstab entry in it. I do have one in my /etc/fstab, though:
mtpfs /mnt/nexus7 fuse user,noauto,allow_other 0 0
Make sure the mountpoint will be writeable.
Anyway, it's all usable but a bit clumsy. Is there a sensible way I
can have the device recognized and mounted via rules in fstab? (Or any
other fixed file?)
I haven't looked to see if there's a way to automount it yet though.
Thanks,
Mark

[gentoo-user] new machine : mail problem : solved
Yet another obscure + unexpected bump to trip over. I carefully copied .fetchmailrc from the other machine -- I'm now using the new one to send this -- made sure it was owned by 'purslow' (user) had read permissions. Not enough ! Could I get error msgs ? How could I find out what it was doing ? Google showed msgs from others with this type of problem what they were doing was running 'fetchmail -v'. I hadn't thought that I could run it myself (slightly red face). RTFM : front + centre it says to try 'fetchmail -vvv --nodetach --nosyslog'. That immediately told me the very non-obvious but crucial information : ~/.fetchmail must have no more permissions than 700. Whyever ? So 'chmod', wait till the next 5-min point at which the script runs yes, there are my test msgs from the older machine waiting for me ! This is yet another example of what was described in a recent thread : Gentoo may need a lot of time to install some time to maintain -- like training, then exercising a dog, perhaps -- , but the problems are rarely 1 layer deep there's lots of help.
