Using plotly and getting "This site can't be reached"
The Chrome browser on the machine shows "127.0.0.1 refused to connect" for
various urls of the form 127.0.0.1:x where x are numbers like
64981, 65029,... About once in 20-40 attempts, the graphs appear.
I ran the same code on a different machine and it created the plots in the
Chrome browser every time. I ran a different Python plotly program on both
machines with similar results.
Everything else I navigate to in Chrome works as expected.
No errors are reported by the plotly code shown below. I also ran the code
in Visual Studio Code with the same results.
I would like to see the information sent to the browser but I have not
figured out how to do that yet.
Any help would be appreciated.

Sqlite3 help
I am building a simple podcast program where I download all the data from a feed with feedparser and store the data in sqlite3. I am spanking new to sqlite and database programming. Should I create the database in the __init__ method of my class, or is that a bad idea. I haven't done any designing that included databases. Thanks!

Re: Generating Filenames from Feeds

I'm asking more for a better way of generating destination filenames, not so much debugging questions. I only put my attempts there to show people that I was actually trying something, and not just relying on people to do my thinking for me. I'm trying to take a feed such as this http://www.theskepticsguide.org/feed/rss.aspx?feed=SGU and parse some useful data out of it for a destination filename. The solution should be general, and not just for this particular feed. Thanks! -- http://mail.python.org/mailman/listinfo/python-list
Generating Filenames from Feeds
HI all,
I am trying to write a podcast catcher for fun, and I am trying to come up with
a way to generate a destination filename to use in the function
urlretrieve(url, destination). I would like the destination filename to end
in a .mp3 extension.
My first attempts were parsing out the and stripping the whitespace
characters, and joining with os.path.join. I haven't been able to make that
work for some reason. Whenever I put the .mp3 in the os.path.join I get syntax
errors. I am wondering if there is a better way?
I was doing something like os.path.join('C:\\Users\\Me\\Music\\Podcasts\\',
pubdate.mp3), where pubdate has been parsed and stripped of whitespace. I keep
getting an error around the .mp3.
Any ideas?
Thanks!!

Essentially, what I am trying to learn by just reading articles on the web is how to access info on the web using Python, i.e. weather data, podcasts, etc... I have never done it before in any language. So, I am trying to do something that I've never done before with a language I barely know.

I will play around with this. I am using Python 3.1, but I can't figure out why I can't use xml.dom.minidom. Here is my code: from xml.dom.minidom import parse, parseString url = 'http://minnesota.publicradio.org/tools/podcasts/ grammar_grater.xml' #just for test purposes doc = parse(url) #I have also tried parseString(url), not to mention a million other methods from xml.Etree, xml.sax etc... all to no avail What the heck am I doing wrong? How can I get this xml file and use the toprettyxml() method. Or something, so I can parse it. I don't have any books and the documentation for Python kind of sucks. I am a complete noob to Python and internet programming. (I'm sure that is obvious :) ) Thanks! Charlie -- http://mail.python.org/mailman/listinfo/python-list

Hooray and thanks again. Secondly, perhaps I overstated my abilities. I have written a couple of websites from scratch that pull data in/out of databases and have formatted their outputs for user consumption. I am by no means a php expert and have never had occasion to use regular expressions for the type of data I've been manipulating.

My response is at: http://www.vbaexpress.com/forum/showthread.php?t=10065 A little confusing (I confused myself) and tried to clear it with a reply to my own note. Using base 12 makes it easy to add key numbers and change the music key.

I'm partial to *Python*, but, the last time I looked, *urllib2* didn't provide a time-out mechanism that worked under all circumstances.

You can get around this by starting an *html* retrieval in its own thread, giving it a deadline, and killing it if it doesn't finish gracefully.

I'd like to maintain not-just-read-only libraries of geographic shapefiles, which are available free from governmental agencies and which are riddled with obvious errors. Typically these are published in compressed archives within which every subdirectory is likewise compressed (apparently for no other purpose than a rather vain attempt at flattening the directory structure, which must be reconstituted on the User's end anyway). Building a comprehensive index to what member name(s) the different map layers (roads, political boundaries, watercourses) have in various political districts of varying geographic resolutions is much more than merely frustrating. I've given it up. However, I believe that once I've located something usable, the thing to do is save a grand unified reference locator (GURL) for it.

PythonTidy 1.10
PythonTidy cleans up, regularizes, and reformats the text of Python scripts. It is released under the GNU General Public License. Python scripts are usually so good looking that no beautification is required. However, from time to time, it may be necessary to alter the style to conform to changing standards. This script converts programs in a consistent way. It abstracts the pretty presentation of the symbolic code from the humdrum process of writing it and getting it to work. This is an upgrade. There was a big problem with earlier versions: Canonical values were substituted for strings and numbers. For example, decimal integers were substituted for hexadecimal, and escaped strings for raw strings. Authors of Python scripts usually use peculiar notations for peculiar purposes, and doing away with the peculiarity negatively impacts the readability of the code. This version preserves the original constants (parsed by *tokenize*) in a literal pool indexed by the value they evaluate to. The canonical values (output by *compiler*) are then translated back (when possible) to the original constants by looking them up in the literal pool. -- http://www.lacusveris.com/PythonTidy/PythonTidy-1.10.python";>PythonTidy 1.10 - Cleans up, regularizes, and reformats the text of Python scripts.

This problem has been fixed I think. No customization should be required to keep block comments from being rendered as in-line comments. Wolfgang Grafen reported that PythonTidy crashed in Python-2.4 because new Abstract Syntax Tree node types introduced in Python-2.5 weren't available. It was trivial to check availability, so PythonTidy should now run in Python-2.4. However, this has not been thoroughly tested and is not guaranteed. PythonTidy can now recode string literals if required, although this capability is turned off by default. See RECODE_STRINGS.

Thank you for trying PythonTidy. o Command-line args: Please give an example of a standard command that I might emulate w.r.t. standard argument use. o Comments: Input is parsed twice: I use *tokenize.generate_tokens* to extract the comments and *compiler.parse* to generate the Abstract Syntax Tree (AST). Other applications usually use the AST to generate bytecode, so it contains no information about comments. The tokens list identifies keywords (and comments and some whitespace) but doesn't group them into statements. I need both: comments *and* functional grouping. Fortunately both the AST and the tokens list carry line numbers to reference the source. Unfortunately the AST line numbers are relative to functional groups and do not necessarily apply to the particular keywords that introduce each group. This makes fixing the position of comments relative to reconstructed code a bit of a challenge. For example, when a comment has a line number in the beginning/ending range of what would normally be considered one command, I have to assume it is an inline comment regardless of how it may have appeared in the original code. Out-of-line comments should appear pretty much as they did in the original code, however. Can you provide an example where they do not? Would you prefer that they be left justified or wrapped? >-~ Doc strings (for modules, class declarations, and functions) are another matter. PythonTidy should not mess with them (unless LEFTJUST_DOC_STRINGS is True). They should appear exactly as originally written. I was taught that code ought to be self documenting and that comments more often than not diminish readability by padding the code beyond what can be comprehended on one page (screen).

advanced module/import/namespace idioms
Every once in awhile I run across a python module that might have statements like: for c in sys.modules[module].__dict__.values(): or import __builtin__ __builtin__.__dict__['_'] = lambda x: x Snurf also does some strange import trickory (see http://bdash.net.nz/svn/snurf/trunk/snurf/dataStore/). While I'm sure none of this stuff is rocket science, but rather just "namespace manipulation" there is very little explanation in the python world that explains these techniques. I've googled around to try to find articles/papers that explain such techniques but cannot find any. Can anyone point out any refereces that discuss such module/import/namespace idioms. -- http://mail.python.org/mailman/listinfo/python-list

The world desperately needs programming languages, frameworks, etc. that allow for the more efficient creation and maintenance of software application - web or otherwise.

As I read through this thread I can't say that I disagree that having more choices is a 'good thing'. However in your example here - I suspect that you are a bit sharper and have a bit more guts than your average code slinger since you appear to be an independent. You've got to remember that your average corporate programmer - which are the folks driving the popularity of programming languages - isn't that sharp/confident. (I don't mean to insult anyone but that just the facts.) They don't do things like evaluate frameworks and make smart choices. This is why there needs to be obvious and singularly popular frameworks and IDE's for Python so that people don't have to think that hard about it. Take Java for example - for the most part its Eclipse and Struts. I know there are many other choices (I've used them), but even the managers know these terms. Very, very few people I know in the IT world know of 'Python', let alone the name of any web framework or an IDE for Python. One of the great things about Python is its simplicty/clarity. Its a shame that there doesn't also exist a clarity of choice for a web framework for Python or an IDE for that matter. Both of these would go a long way in motivating people to take a look at Python and realizing what great value it has to offer the IT world in solving problems. -- http://mail.python.org/mailman/listinfo/python-list
Re: Which Python web framework is most like Ruby on Rails?
> People keep talking about Python's wealth of web frameworks as if it > were a bad thing. I disagree somewhat. While variety and choice are nice, sometimes having too many choices may inhibit people from trying the language because they don't know where to start in terms of framworks. Maybe I'm wrong but if there is an element of truth what I suggest then that would be a terrible shame since Python is such a great language. Python's popularity might improve if there were a bit more unity within the Python community with regards to (web) frameworks. -- http://mail.python.org/mailman/listinfo/python-list
Python IDE (was: PythonWin troubleshooting)
Apparently not too many people use or are interested in PythonWin. I'm giving up on it. It used to work pretty good. I'm lucky that I have found PyScripter (http://www.mmm-experts.com/) a python IDE for the windows platform which is much more stable and has more features that PythonWin. If you are doing Python development on Windows I'd recommend taking a look at it. I'm also evaluating Wing IDE. I may have another post with comments on it for anyone who might be interested. -- http://mail.python.org/mailman/listinfo/python-list

I think the problem is related to some sort of shell hook as it goofs up not only PythonWin, but other windows applications and windows itself. Can't get the context menu to work in explorer, the task manager from the task bar, etc. Something is really goofed up! The problem only appears when PythonWin is running or was running and is hung in memory from a non-clean PythonWin shutdown. -- http://mail.python.org/mailman/listinfo/python-list

Sticking with 2.4.2 I reverted to win32 ext 204 and problems were the same or worse. Then I uninstalled both, removed the dangling py*24.dll and then installed "ActivePython 2.3.5.236". All the problems went away. I hate to go back to 2.3 cause there are some nice updates in the 2.4 library that I'd like to have.

PythonWin troubleshooting
Having problems with PythonWin on Windows XP SP1. Shortly after startup and trying to debug I see: LoadBarState failed - LoadBarState failed (with win32 exception!) Things go down hill quickly from there. From there I see stuff like: [Dbg]>>> Traceback (most recent call last): File "C:\Python24\Lib\site-packages\pythonwin\pywin\framework\winout.py", line 111, in OnRClick apply(menu.AppendMenu, appendParams) win32ui: ::AppendMenu failed - no error code is available >From there out none of the menus or toolbars work. This is on Windows/Python 2.4.2. Both the ActiveState or regular Windows distribution. I've cleaned up any old Py*23 DLL's. Uninstalled and re-installed several times. Suggestions please. -- http://mail.python.org/mailman/listinfo/python-list
Re: Dectecting dir changes
I do need to stick to FTP though as indicated I could run it on a different port. Limit comes more from the client side capabilities. Did some reading about twisted and I now understand that things in general are single threaded. I started working my way through the twisted finger tutorial. While it appears that it may be useful for someone writing a new protocol it doesn't seem to useful for someone just trying to hook into an existing one. While I do appreciate the suggestions but I have to say that if the twisted folks spent half the time writing documentation as they do code - twisted would probably get used a lot more Python folks. Didn't get much encouragement/assistance from the twisted irc channel either. Perhaps the fella I chatted with hadn't had his coffee yet ;) -- http://mail.python.org/mailman/listinfo/python-list
Re: Dectecting dir changes
Hmmm, that is an interesting idea. I've noticed the new book on Twisted, thinking about picking it up. I assume that this little snippet will handle multiple/concurrent incoming transfers via threading/sub-process, is scalable, secure, etc? I could even run it on a non-standard port making it a bit more (ob)secure. -- http://mail.python.org/mailman/listinfo/python-list

Re: Dectecting dir changes
Is this on Solaris? I think you may have missed my point. I don't have fcntl.py on my Solaris box so how do I know what signals that I can used to monitor a directory for modification. In other words will the following work? fcntl.fcntl(self.fd, fcntl.F_NOTIFY, fcntl.DN_DELETE|fcntl.DN_CREATE|fcntl.DN_MULTISHOT) Without fcntl source, which the python documentation suggests that I look at, I don't know if any of these constants apply to the Solaris platform. -- http://mail.python.org/mailman/listinfo/python-list
Dectecting dir changes
I need to write a daemon for Solaris that monitors a directory for incoming FTP transfers. Under certain conditions, when the transfer is complete I need to send an email notification, and do other stuff. Win32 provides FindFirstChangeNotification(), but as best I can tell this isn't supported on Solaris. I am thinking of using the approach suggested here http://tgolden.sc.sabren.com/python/win32_how_do_i/watch_directory_for_changes.html which is: import os, time path_to_watch = "." before = dict ([(f, None) for f in os.listdir (path_to_watch)]) while 1: time.sleep (10) after = dict ([(f, None) for f in os.listdir (path_to_watch)]) added = [f for f in after if not f in before] removed = [f for f in before if not f in after] if added: print "Added: ", ", ".join (added) if removed: print "Removed: ", ", ".join (removed) before = after My concern with this is that a change may be detected before the ftp daemon process is done writing the file to disk. I don't want to take any action until the file is written and closed. I know that I could pole a new file looping to check to see if it's file size is changing but the timing of such a loop is subject to I/O buffering and is otherwise not elegant. Googling shows other solutions using fcntl (http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/217829) but it appears that this only works on Linux. While I'm at it I'm going to throw in a grump about the Python documentation of fcntl. The doco indicates to read the source for fcntl.py to lookup the constants representing the different types of events/signals that are avaiable. However fcntl on some platforms seems to be implemented as a binary leaving no way to look up the contants for the platform. Suggestions? -- http://mail.python.org/mailman/listinfo/python-list

Re: Why doesn't IDLE editor windows have horizontal scrollbars?
Well I don't want to start yet another thread on IDE's. I've googled and all of that an am aware of most of the IDE's that are out there. I am curious if there is someplace where statistics have been captured on what IDE's most people are using. Since IDLE ships with Python I assume a lot of people use it. I've been a PythonWin user for years but it has shortcomings, isnt' being developed further and doesn't run on FreeBSD, my other platform. -- http://mail.python.org/mailman/listinfo/python-list
