The worst part is we don't have any exe file specifically for IDLE. I mean windows has to choose whether to edit or compile. In my case, the file associated with my .py files is python.exe (c:/python27/python.exe). I still don't understand why its not opening in IDLE. If I am wrong, is there any special application (exe file) for IDLE so that I can configure to?? ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

To make it even better I will now assume you want the file to be opened by IDLE in a script (edit) window. So an even better explanation is "when I double-click the file I want it to be opened by IDLE in a script (edit) window." On the other hand if I take what you say literally all you want to do is open IDLE. This is probably not the case. Again I say it is well worth the effort to be as thorough and explicit as possible. So that we can reproduce the behavior you want. -- Bob Gailer 919-636-4239 Chapel Hill NC ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

You will should geta "context menu" Do you see Edit with IDLE? If so, choose that. Also take a look at the Advanced settings for the file type .py On my windows 2003 server in the Explorer I click Tools -> Folder Options -> File Types, select .py then click Advanced. Here I see Edit with IDLE I select that and click Edit and see "D:\Python27\pythonw.exe" "D:\Python27\Lib\idlelib\idle.pyw" -e "%1" in your case that should read "C:\Python27\pythonw.exe" "C:\Python27\Lib\idlelib\idle.pyw" -e "%1" If you don't have an Edit with IDLE entry, click New and add one. If you want that to be the double-click behavior click Set Default. If your OS is different the route to the file associations may be different. -- Bob Gailer 919-636-4239 Chapel Hill NC ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
[Tutor] feedback on writing pipelines in python
Hi Guys I am in the process of perl to python transition for good. I wanted to get some feedback or may be best practice for the following. 1. stitch pipelines : I want python to act as a glue allowing me to run various linux shell based programs. If needed wait for a program to finish and then move on, logs if required 2. run the same pipeline but on a local grid if required. (SGE flavor mainly) Any modules which can reduce the number of lines i write will be helpful. Thanks! -Abhi ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] feedback on writing pipelines in python
Hi Steve I agree Steve perl is perfectly fine for the stuff I described but I am also interested trying alternatives. I am seeing quite interesting data handling stuff coming up in Python and I would like to try and sometimes as a programmer I dont like so many ways of doing the same things but it is subjective. Having many options can be good for some. -Abhi On Wed, Mar 21, 2012 at 11:20 AM, Steve Willoughby wrote: > On 21-Mar-12 11:03, Abhishek Pratap wrote: > >> Hi Guys >> >> I am in the process of perl to python transition for good.

That's not usually the behavior you want for .py files. Once you gain experience you will likely have a lot of programs written in python, all will be in files ending .py. So you will probably want a double click to run those programs. (You should really only use IDLE to write and debug your programs not for running them) So it's usually better to add an edit option to your context menu (right click) to edit in IDLE. The ActiveState installer sets that up for you the official python windows installer doesn't - or didn't last time I used it - over a year ago now. Bob has shown you what his settings look like and how to set it up if you don't already have that option. Just create a new menu entry rather than modifying the Open entry. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

If needed wait for a program to finish and then move on, logs if required Python by default reads/writes to stdin/stdout so you can do stuff like: $ foo.py < fred.txt | bar.py | baz.py > joe.txt You can also control that explicitly by importing the sys module and reassigning sys.stdin/sys.stdout or even reading and writing explicitly from those file like objects. You can also use the subprocess module to execute other programs (either Python or any other ind of executable file) in a sub procvess or a separate shell and get full control over the pipes, stdin, stdout and stderr. Of course that flexibility brings a price and the full power of subprocess.Popen is a little complex but there are lots of examples in the documentation. 2. run the same pipeline but on a local grid if required.

[Tutor] opening a Qt .py file from within another python app.
Evening all;
I am trying to import a Python QT file, that had been generated from a ui file
into another python app.
I have imported it, without generating an error, but the Qt window isn't
opening. I have spent the afternoon googling the issue, have found numerous
articles, but none that have seemed to work for me.
I have tried: import file, from file import *, and a slew of
other suggested ways to get it to run, all to no avail.
I have tried to call the Class and other Def functions from the Qt file, up to
and including __main__, but no good.
I have spend well over an hour perusing the Python on line Doc's, but If i had
stumbled upon the answer I guess I am too slow to have recognized it.
I had come across this great piece on Stack overflow:
There are more than a few ways. I'll list them in order of inverted preference
(i.e., best first, worst last):
1. Treat it like a module: import file. This is good because it's secure,
fast, and maintainable. Code gets reused as it's supposed to be done. Most
Python libraries run using multiple methods stretched over lots of files.
Highly recommended. Note that if your file is called file.py, your
import should not include the .py extension at the end.
2. The infamous (and unsafe) exec command: execfile('file.py'). Insecure,
hacky, usually the wrong answer. Avoid where possible.
3. Spawn a shell process: os.system('python file.py'). Use when desperate.
None of which had gotten the Qt window to open. Yet when I run it directly, on
it's own, it open's and the Qt window is displayed.
I am hoping it is a relatively simply Task to accomplish, but beyond the
stunted abilities of my limited knowledge.
At this point I am simply trying to get the Qt window to open from the second
python app. After which I have a steep hill to climb to try to connect the
input from the one app to the signals of the other, but that is for another day.
Any and all help, would truly be appreciated.
python3.2, Linux Ubuntu 11.10
Thank you
Ken
