RE: Linux shell to python
You can do this with one subprocess.Popen and some python commands. The alternative is to pipe some subprocess.Popen commands together. Or for the quick way out (but I think you better stick with bash scripting then): http://pypi.python.org/pypi/sarge/ Don't know about it's stability/ubs/etc, never used it. -Original message- From:Vikas Kumar Choudhary vikas.choudh...@yahoo.co.in Sent:Mon 30-07-2012 09:34 Subject:Linux shell to python To:python-list@python.org; Dear friends, I just joined the group. I was trying porting from bash shell to python. let me know if someone has tried to implement (grep and PIPE) shell commands in python `lspci | grep Q | grep $isp_str1 | grep $isp_str2 | cut -c1-7' I tried to use python subprocess and OS.Popen modules.

RE: simplified Python parsing question
Another possibility is to use the ast module of python: http://docs.python.org/library/ast.html The only problem with that module, is that everything you parse must be correct, otherwise it throws an exception, I don't know if that's a problem for your project? -Original message- From:Eric S. Johansson e...@harvee.org Sent:Mon 30-07-2012 12:00 Subject:Re: simplified Python parsing question To:python-list@python.org; On 7/30/2012 5:25 AM, Laszlo Nagy wrote: Did you try to use pygments? http://pygments.org/docs/api/ thanks, I'll take a look. I would first tokenize the code, then divide it by statement keywords. Finally, you just need to find expression/assignment statements in the remaining sections. (Maybe there is a better way to do it.) yeah the problem is also little more complicated than simple parsing of Python code. For example, one example (from the white paper) *meat space blowback = Friends and family [well-meaning attempt] *could that be parsed by the tools you mention? I suspect not but this is what I need to generate using speech recognition because it's easily spoken. A more complex example might be something like new base = OS path-base name (old path) or if OS base exists (current path): new base name = OS path base name(current path) What's particularly cute here is that using the translation technique I can actually describe the full object method path with a minimum of speaking overhead. Python is great. :-) But the questions remain, will these tools are stuff like this? -- http://mail.python.org/mailman/listinfo/python-list -- http://mail.python.org/mailman/listinfo/python-list
Re: Is Python a commercial proposition ?
Scripting is one of the strong sides of python. I use it al the time to quickly write a script to analyze something or automate. That is probably the reason it is used to glue (script) things together and is embedded in some programs (like Maya and such). At the company we're using python and django for websites, from small micro sites till big enterprise sites. Currently I'm working on a highly configurable application to control a maya render cluster. You can also use it for testing and even frontend testing. I think you can use python for almost everything, tough I think it's less suitable for non-web gui applications. lipska the kat lip...@yahoo.co.ukschreef: Pythoners Firstly, thanks to those on the tutor list who answered my questions. I'm trying to understand where Python fits into the set of commonly available, commercially used languages of the moment. My most recent experience is with Java. The last project I was involved with included 6775 java source files containing 1,145,785 lines of code. How do I know this? because I managed to cobble together a python script that walks the source tree and counts the lines of code. It ignores block and line comments and whitespace lines so I'm fairly confident it's an accurate total. It doesn't include web interface files (mainly .jsp and HTML) or configuration files (XML, properties files and what have you). In fact it was remarkably easy to do this in python which got me thinking about how I could use the language in a commercial environment. I was first attracted to python by it's apparent 'Object Orientedness' I soon realised however that by looking at it in terms of the language I know best I wasn't comparing like with like. Once I had 'rebooted the bioware' I tried to approach python with an open mind and I have to say it's growing on me. The questions I have are ... How is python used in the real world. What sized projects are people involved with Are applications generally written entirely in python or is it more often used for a subset of functionality. I hope this is an acceptable question for this group Many thanks Lipska -- Lipska the Kat: Troll hunter, sandbox destroyer and farscape dreamer of Aeryn Sun -- http://mail.python.org/mailman/listinfo/python-list -- http://mail.python.org/mailman/listinfo/python-list
[issue6833] incorrect: failed local variable referenced before assignment
New submission from Paul van der Linden p...@soulbase.nl: The attached python file will give the following output, which is incorrect behavior as far as I know: this will fail failed local variable 'in_std' referenced before assignment this won't fail Not failed this won't fail either Not failed This is tested on windows with python2.6(standard msi) and on centos 5.3 with python2.6 (custom rpm), python2.4 (system rpm), freebsd with python2.5 (system package), python2.6 (hand compiled) and python3.0 (hand compiled).
