Plotting multiple datasets with gnuplot
Hi, I'm trying to get gnuplot to display multiple data series on a single plot using gnuplot in python. I've searched around and haven't found a solution to how to do this when I have a variable-length list of plots to add. For example, the following code will work: plotData1 = Gnuplot.PlotItems.Data(data1, title=title1) plotData2 = Gnuplot.PlotItems.Data(data2, title=title2) g.plot( plotData1, plotData2 ) [I've removed the rest of the code for clarity] But how can I do the following instead: data = [] ... # Populate data ... plots = [] for dataSet in data: plots.append(dataSet) g.plot(plots) I don't know how many plots I'll be wanting to plot, but the number will be roughly 15-20 and it seems ridiculous to have to hand-write individual setup for each plot when I should be able to just loop through the datasets and add them to gnuplot automatically. Any help would be much appreciated!

mxDateTime history (Re: mktime, how to handle dates before 01-01-1970 ?)
John Yeung wrote: On Oct 6, 4:10 pm, Stef Mientki stef.mien...@gmail.com wrote: thanks guys, mx works a bit better Another popular Python date library is dateutil: http://labix.org/python-dateutil It gives a certain amount of credit to mxDateTime (praising it but not being very clear how they are related; there is some mention of using the specification of mxDateTime). History goes a bit like this: mxDateTime was the first Python library to implement native date/time types for Python. I started the project in 1997. Back then I had a good look around at the various date/time libs and then decided to take a little more academic approach to the whole thing. The result was that you only need two basic types in mxDateTime: the DateTime object, which refers to a point in time, and the DateTimeDelta object, which allows measuring the time span between two such points. Note the absence of a Date object. These would be date/time range objects since they apply to the timespan of a full day with a time reference point at midnight. I decided to leave such ranges for a later stage in development - and have so far, never needed them :-) A bit later in 1998, I also added the RelativeDateTime object, which allows doing date/time calculations based on relative terms, e.g. x minus one year (which could mean 356 or 366 days depending on the year), first of next month (which could mean anything from 1-31 days), last of next month, Tuesday in 3 weeks, last Monday next month, etc. And again a bit later in 2000, I added the RelativeDateTimeDiff object which works a bit like an age function in that it tries to determine the RelativeDateTime value which has to be applied to a DateTime object in order to reach another one, say from your birthday to today. The result reads is more user- friendly than a bare DateTimeDelta, e.g. you get 40 years, 6 months, 3 days instead of 14796 days. In 2002 Zope Corp initiated the development of the datetime module, which borrowed a lot of design and API ideas from mxDateTime. However, it did not provide a date/time string parser and also misses out on lots of the other good stuff you can find in mxDateTime. Gustavo Niemeyer started to work on a date/time parser based on the datetime module - that's the python-dateutil library. He also added a relative date/time object which was one of the bits Zope Corp left out in the datetime module from mxDateTime and added some other things that are not currently part of mxDateTime: recurring events and time zones. mxDateTime continues to be actively developed - mostly driven by eGenix' own needs and experience we find in projects. Whenever we need something new, we can just add it to mxDateTime and since its release cycle is not bound to Python's, such enhancement are more readily available to others as well. Overall, my impression is that the datetime module was designed on the drawing board without actually touching real life usage scenarios. We've just done a project that used the datetime module for date/time related things instead of mxDateTime and found that while the implementation is similar to mxDateTime (naturally, see above), many useful features you find in mxDateTime are not available on the datetime objects. For future releases, we'll make the interaction between the two implementations more user friendly, e.g. it should be possible to pass a datetime object to mx.DateTime.DateTimeFrom() and call a method on DateTime objects to get a datetime module object with the same values. I would say mxDateTime and dateutil are the two heavyweights in this arena. As you would expect, they have a lot of overlapping functionality and which one is used is often just a matter of taste, or whichever one you happened to find first. One thing that dateutil provides that mxDateTime doesn't is support for lay person month operations. That is, as far as I can tell, mxDateTime tries not to dirty itself with the messy business of month arithmetic, whereas dateutil rolls up its sleeves and takes an honest stab at it. If you are writing a calendar/appointment application, or other end-user-facing program, I would expect dateutil to be a little more helpful. Month arithmetic is a bit of a mess, since it's not clear how to map e.g. Jan 31 + one month. mxDateTime does support month arithmetic via the RelativeDateTime object, but I'm not all that happy with the solution to the above problem. The alternatives are basically deciding between loosing data or raising an exception - both aren't really all that nice. Perhaps I'll just add a parameter to allow customization of the behavior depending on application needs. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, Oct 09 2009) Python/Zope Consulting and Support ...http://www.egenix.com/ mxODBC.Zope.Database.Adapter ... http://zope.egenix.com/ mxODBC, mxDateTime, mxTextTools ...

Re: mxDateTime history (Re: mktime, how to handle dates before 01-01-1970 ?)
Month arithmetic is a bit of a mess, since it's not clear how to map e.g. Jan 31 + one month. Jan 31 + one month usually means add one to the month value and then keep backing off the day if you get an exception making the date, so you'd get Feb 31, exception, Feb 30, exception, Feb 29, possibly an exception, and possibly/finally Feb 28th. This makes pretty intuitive sense to most folks and is usually what's meant. I've found that issues and confusion stem more from the non-commutative reality that Jan 31 + (1 month) + (-1 month) != Jan 31 + (-1 month) + (1 month) or the non-associative Jan 31 + (1 month + 1 month) != (Jan 31 + 1 month) + 1 month :-/ So yes, messy it is! -tkc -- http://mail.python.org/mailman/listinfo/python-list

elif table[0] == 't': # This is a store subtype table
bits = string.split(table, '0')
sst.append(bits[2])
sstp.append(bits[1])
subtypes = dict(zip(sstp, sst))
When I print these out to screen, I get this:
sst: ['doctors', 'patient']
sstp: ['prescriptions', 'prescriptions']
subtypes: {'prescriptions': 'patient'}
Why do I only get one item from sst and sstp zipped? Why not both??
I think you have a logic problem that's not shown in that code sample:
sst = ['doctors', 'patient']
sstp = ['prescriptions', 'prescriptions']
zip(sst,sstp)
[('doctors', 'prescriptions'), ('patient', 'prescriptions')]
dict(zip(sst,sstp))
{'patient': 'prescriptions', 'doctors': 'prescriptions'}

The issue is:
subtypes = dict(zip(sstp, sst))
If you remove the dict, you'll see the following:
[('prescriptions', 'doctors'), ('prescriptions', 'patient')]
When this is converted to a dict, the first element of each tuple is placed
as the dict's key, and the second as the value. This means that you have two
keys of prescriptions, and so the final one happens to be chosen as the
value.
Changing the line:
subtypes = dict(zip(sstp, sst))
to:
subtypes = dict(zip(sst, sstp))
as I believe Stephen misread it to be causes the zip operation to return:
[('doctors', 'prescriptions'), ('patient', 'prescriptions')]
and thus the dict will contain:
{'patient': 'prescriptions', 'doctors': 'prescriptions'}

Re: Zip Question
You're right...how strange. Here's the whole code:
tables = []
bst = []
bdt = []
spt = []
sst = []
sstp = []
cursor.execute('show tables;')
all = cursor.fetchall()
for a in all:
tables.append(a[0])
for table in tables:
if table[0] == 'b': # This is a basic table
if table[1] == '0': # This is a basic static table
bst.append(table)
# elif table[1] == '1': # This is a basic dynamic table
#bdt.append(table)
# Basic dynamic tables, like pic below, have to be manually created.
elif table[0] == 's': # This is a store table
if table[1] == '0': # This is a store primary table
spt.append(table)
elif table[0] == 't': # This is a store subtype table
bits = string.split(table, '0')
sst.append(bits[2])
sstp.append(bits[1])
subtypes = dict(zip(sstp, sst))
print sst
print 'br /'
print sstp
print 'br /'
print subtypes
print 'br /'
This is what prints out:
['doctors', 'patient']
['prescriptions', 'prescriptions']
{'prescriptions': 'patient'}

Yeah, I think the arguments to zip() were probably just flipped in Victor's
code. Unless he wants a result different then what I assume is expected. I
assume he's expecting {doctors: prescriptions, patient:
prescriptions}. If instead its something more like {prescriptions:
[doctors, patient]} then zip() isn't how to accomplish it.

Python 2.5 execfile() works only once, why ?
hello,
I'm working on a kind of IDE, to build and distribute Python programs.
One of the parts is editing a build file for py2exe and running the
modified script.
In the script editor I've an accelerator key, to launch these tasks:
- save modified script file
- run modified script file
- catch log and error information from py2exe
- launch the distro executable
self.Edit.SaveFile ( self.Edit.Filename )
Globalsx = {}
#Globalsx [ 'stdout' ] = self.Log
execfile ( self.Edit.Filename, Globalsx )
The above code (with or without the stdout redirection),
works perfect,
... the first time ...
but does (almost?) nothing (doesn't crash, try / except around execfile),
although the source file self.Edit.Filename has changed.
Could someone give me an explanation, why this happens ?
It would be great to have a work around.
I've currently switched to Popen, but can't get output / error piping
working fluently.

Re: No threading.start_new_thread(), useful addition?
I personally find it much cleaner this way. Also, why should any code care in which thread it is executed? Why should I have to derive a class from some other only because I want to run one of its functions in a separate thread? I think you are right! Especially that you can (and probably will) call other methods from your thread. For example, functions from the standard library. Or use methods of objects that where created in a different thread. I think we can say, you must call methods of other (not Thread) objects if you ever want to do something useful in your thread. Now I'm beginnig to agree with you, Ulrich. We have threading.enumerate() - it can be used to list active threads. So if you only want to start a function in a separate thread, then you do not really need the Thread object. Then we do you HAVE TO create a Thread object explicitely? Of course you can easily create a nice decorator like this: import threading def threadlaunch(func): def launcher(*args,**kwargs): thr = threading.Thread(target=func,args=args,kwargs=kwargs) thr.start() return thr return launcher And then do something like: import time @threadlaunch def print_something(w,s): print please wait... time.sleep(w) print s thr = print_something(3,Test) print started print_something in,thr How about that?

There are some issues pending with syslog-ng and Python logging (see issue6444) and in general syslog over TCP is not necessarily all that reliable, see http://blog.gerhards.net/2008/04/on-unreliability-of-plain-tcp-syslog.html The requested change is not difficult to make, but it will be difficult for me to test because in general end-to-end testing for network APIs is not there in the standard regression test suite, and I don't have a setup where I can test it independently. So I'm sorry to say I will not be able to give this a very high priority at the moment (unless another committer can test this). Just curious (as no one has asked for this before) why you're using TCP, given that it doesn't eliminate message loss and it is slower and has less support than UDP? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7086 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue7092] Test suite emits many DeprecationWarnings when -3 is enabled
New submission from Jean-Paul Calderone exar...@divmod.com: If the test suite is run with -3, many deprecation warnings are reported. Quite a few are generated by code in the tests themselves, but many are from constructs in the stdlib which are different or no longer supported in 3.x. Even aside from the fact that many of these warnings being caused by code which I think many people would agree is not ideal, I think it is important for these warnings to be fixed for Python 2.7. Since the 3.x porting guidelines recommend that projects first run their test suite with -3, these warnings are going to be generating extra noise for developers to filter through when they try porting their code to 3.x. They shouldn't need to wade through stdlib warnings to find warnings about their own code.

[issue7086] logging.handlers.SysLogHandler with TCP support
Jr Aquino jr.aqu...@citrixonline.com added the comment: Thank you for responding so quickly Vinay. I am using a multitude of syslog daemons, from syslog, syslog-ng, rsyslog, and several different proprietary SIEM/SEM Log archiving appliances. I work in the security sector. (Yes I have read Rainer before, its actually a big reason I am writing the tool that I am working on. Gaps in logs are a real world problem!) Regarding issue 6444, these users are attempting to use SysLogHandler to write to the local system's syslog sockets. A way of piggy backing on the configuration of the local systems logging daemon. What I am actually doing is ignoring the local systems syslog, and sending the syslog packets directly to a remote syslog server. This is to replay syslog data that may have been previously lost due to connectivity outages. My tool can also be used to send the data to an external server for forensic reasons. I believe the answer to your last question also sheds light on your first question! The reason that I am looking to add TCP is because a lot of new data center architectures are heavily utilizing tcp syslog in a chained / centralized environment. I am also seeing a lot of preferential treatment of tcp syslog on logging appliances such as Loglogic. I am sorry to hear that your test environment is lacking the regression suites that you need. I do hope that another commiter can test for us. Syslog is an old technology and I hope that more efforts like mine and Rainer's can help to identify and correct deficiencies in the design. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7086 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue7095] Multiprocessing.Array(lock=False) fails
New submission from schlesin schle...@cshl.edu:
The documentation for the Multiprocessing.Array says:
multiprocessing.Array(typecode_or_type, size_or_initializer, *,
lock=True)¶
...
If lock is False then access to the returned object will not be
automatically protected by a lock, so it will not necessarily be
“process-safe”.
...
However:
In [48]: mp.Array('i',1,lock=False)

I.e. it looks like lock=False is not actually supported.

[issue7060] test_multiprocessing dictionary changed size errors and hang
R. David Murray rdmur...@bitdance.com added the comment: Benjamin tried reverting the weakref patch, but that didn't fix it. Turns out the problem is the other patch in that merge, that adds saving of the exception to AssertRaises. Adding Kristjan as that was his patch. (The tests pass with the weakref patch applied and the unittest patch reverted, by the way.) -- nosy: +krisvale ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7060 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
