Need to modify a Python Gui
Hi everybody,
I have a Python GUI that displays some data in labeled fields. As new data
comes in the fields clear and the old data is lost. I need to make a text box
in the GUI that will display the cleared data in a scrolling list. I also need
this scrolling list to be logged to a file in comma-seperated values for
analysis at a later time. The fields I need to scroll and log are labeled in
the “class TrafficPane(wx.Panel):” starting at line 64.
Thanks

need to print seconds from the epoch including the millisecond
i am using 2.7. I need to print the time in seconds from the epoch with
millisecond precision. i have tried many things but have failed. heres my
latest:
from time import time, strftime
from datetime import datetime, time
# write date, time, then seconds from epoch
self.logfile.write('%s\t'%(strftime("%Y-%m-%d",)))
self.logfile.write('%s\t'%(now.strftime("%H:%M:%S",)))
self.logfile.write('%s\t'%(now.time()))
what am i doing wrong? what should i be doing here? Thanks!

OK i did what you said but I am only getting 2 decimal places.
Why is this and what can I do to get the millisecond?

thanks a bunch. the "%.6f" was the cure. can you please point me to the doc

the formatting:

outputting time in microseconds or milliseconds
Hey everybody,
I am using 2.7 on Ubuntu 12.10. All I need to do is to print time with the
microseconds. I have been looking at the docs and trying things for about half
a day now with no success. Currently my code looks like this:
# write date and time and microseocnds
self.logfile.write('%s\t'%(str(strftime("%Y-%m-%d",
self.logfile.write('%s\t'%(str(strftime("%H:%M:%S",
self.logfile.write('%s\t'%(str(time(
the output looks like this:
2013-08-02 06:01:43 00:00:00
2013-08-02 06:01:43 00:00:00
2013-08-02 06:01:43 00:00:00
2013-08-02 06:01:43 00:00:00
2013-08-02 06:01:43 00:00:00

2013-08-02 06:01:44 00:00:00
as you can see in the 2nd column the observations occur with 'fractional
second' frequency, up to 8 or 9 per second. You can also see my latest attempt
to get the microseconds in the third column is not working. It would really be
great if python had a way to just tack the microseconds (actually i think
milliseconds would be better) on to the second (in the 2nd column) as a
fraction. If this is not possible I need the extra write statement for just the
microseconds (millisecond if possible).
Any help will be much appreciated.
Thanks!

Re: outputting time in microseconds or milliseconds
so you are saying that
self.logfile.write('%s\t'%(str(time(
should be:
self.logfile.write('%s\t'%(str(time.time(
???
Thanks

Thanks Skip, what i currently i have is:
dt = datetime.now()
and
self.logfile.write('%s\t'%(str(strftime("%Y-%m-%d",
self.logfile.write('%s\t'%(str(strftime("%H:%M:%S",

is the third column is only the microsecond? how could i get this to write

Re: outputting time in microseconds or milliseconds
ok so now i import the module like this:
from time import strftime, time
i made the write statement like this:
self.logfile.write('%s\t'%(str(strftime("%Y-%m-%d",
self.logfile.write('%s\t'%(str(strftime("%H:%M:%S",
self.logfile.write('%s\t'%(str(time(
(oh and btw,i know the code is hacker ugly).

the first two columns are for eyes so if they are a microsecond apart it
doesn't matter. the numbers in the third column are for calculating duration
which is where i need the precision.
Why is it only giving me the centisecond precision? the docs say i should get
microsecond precision with the code i put together.
Thanks!

I put the exact same post in the gnu-radio homebrew forum and the moderated closed the thread; I am not sure why because he wouldn't answer me but he closed it. Ive posted this question in so many places with but no luck so far. As a workaround I removed the block "wxgui_fftsink2", as that block is not integral to the signal processing. And that is the goal of "op25_grc.py", to decode digital radio signals. This code block is run in GNU radio companion (GRC) along with many others in the signal processing path . GRC is a GUI where one can manage the code (ie. use a flow graph instead of coding) needed to process radio signals with a personal computer; sort of like the IDEs people use to create executables. One can create there own processing blocks or use blocks that others have created. Thanks for your cooperation and patience! I am going to keep working on this as time allows. -- http://mail.python.org/mailman/listinfo/python-list

thats the file path. the directory "bin" in my home directory. in bash it
obviously looks like this "~/bin" using the file system folder the path is
home/Home/bin. i have tried commands like, export
PYTHONPATH=${PYTHONPATH}:/users/matt/bin or home/matt/bin or Home/home/bin and
nothing has worked.
from what ive found on the web the Python import process is notoriously
underspecified, notwithstanding i was under the impression that PYTHONPATH is a
global variable that i can add directories to at anytime to tell Python where
to look, without having to add some sort of code to every program. is this
impression incorrect? is there some code i need to add to the Python program
call the modules in the "bin" dir?

Re: Python module import failed error
Here is the PYTHONPATH >>> import sys >>> sys.path ['', '/home/matt', '/users/matt/bin', '/home/matt/bin', '/Home/bin', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PIL', '/usr/lib/python2.7/dist-packages/gst-0.10', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/python2.7/dist-packages/ubuntu-sso-client', '/usr/lib/python2.7/dist-packages/ubuntuone-client', '/usr/lib/python2.7/dist-packages/ubuntuone-control-panel', '/usr/lib/python2.7/dist-packages/ubuntuone-couch', '/usr/lib/python2.7/dist-packages/ubuntuone-storage-protocol', '/usr/lib/python2.7/dist-packages/wx-2.8-gtk2-unicode'] -- http://mail.python.org/mailman/listinfo/python-list
AttributeError: ' ' object has no attribute ' '
I am using Ubuntu 12.10, and Python 2.7.3, GNU Radio Companion v3.6.3. I get the this error in terminal: in __init__ self.wxgui_waterfallsink2_0.set_callback(wxgui_waterfallsink2_0_callback) File "/usr/local/lib/python2.7/dist-packages/gnuradio/gr/hier_block2.py", line 54, in __getattr__ return getattr(self._hb, name) AttributeError: 'gr_hier_block2_sptr' object has no attribute 'set_callback' I have been getting this error in multiple programs. So what is stopping the program here? There is no Attribute .set_callback obviously. But where is this attribute missing from exactly and how do i put it where it should be? -- http://mail.python.org/mailman/listinfo/python-list
Re: AttributeError: ' ' object has no attribute ' '
yeah im not a programmer, i have not wrote anything here that i am trying to use; i am an end user. my only interest in this code is to get the program working. so i have to do what i have to do try to get it working. im just hoping that what im going through here, this error thats coming up here, has been encountered by someone else that has solved it and that someone will see this and care to tell me how fix it. -- http://mail.python.org/mailman/listinfo/python-list
