scatter plot error - possibly data type
Hi,
Can anyone help me with this error?
I suspect it is something to do with the data type, but don't know how to
resolve.
I'm trying to plot a 2 user system dates against each other and am getting the
error below.
print(type(DialogUsers.TRDAT))

Ah. I finally solved the issue though I don't know what the problem itself it.
The problem, shown with a simple example
Python 3.7.2 (tags/v3.7.2:9a3ffc0492, Dec 23 2018, 22:20:52) [MSC v.1916
32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>
>>> print ("hallo")
hallo
>>> print ("h\allo")
hllo
>>> print (r"h\allo")
h\allo
>>>
The first line is a simple print statement to print the text "hallo"
(which is Dutch for "hello")
In the second line i added a '\' (backslash), the letter 'a' seems to be
missing, unless audio on your computer works. If audio works you will
hear a bell.
(see: https://docs.python.org/2.0/ref/strings.html )
In the third line a 'r' is put in front of the string, and now the 'a'
is shown again (and also the '\').
In your path there is something like '...programs\assertion\CNN..'.
Python does see a '\a', after 'programs', and before 'ssertion', and
tries to sound a 'bell'

So, my test program is importing design file. Both test and design file are have the following lines: #Create and configure logger filename = os.path.join(os.path.dirname(os.path.realpath(__file__)), 'test_5.log') logging.basicConfig(filename=filename, filemode='w', format='%(asctime)s %(message)s') #Creating an object logger = logging.getLogger() I think this is causing the issue. Anyway, I am able to log from the test program. However, I am not able to log anything from design program. I will open a separate thread on this topic. -- https://mail.python.org/mailman/listinfo/python-list
Multiple log files using logging module
I have a test program that imports a design program. Both the programs need to log messages. I have tried the following: 1) Both the programs have the following lines: for handler in logging.root.handlers[:]: logging.root.removeHandler(handler) #Create and configure logger filename = os.path.join(os.path.dirname(os.path.realpath(__file__)), '<>') logging.basicConfig(filename=filename, filemode='w', format='%(asctime)s %(message)s') #Creating an object logger = logging.getLogger() #Setting the threshold of logger to DEBUG logger.setLevel(logging.DEBUG) replace <> above with respective log file names for test and design programs. However, the test program logs the messages but not the design program. 2) I removed the above lines from design program altogether hoping that the messages will appear in the same log file. There is no error, however, no message is logged from the design program. I would like to get comment from members here as well as some simple programs to illustrate this ... -- https://mail.python.org/mailman/listinfo/python-list

As mentioned in your other thread, you should take note on HOW you put the filenames in there. How do you see the end of the line starting with 'filename =...'?

I don't think that's the problem. Rather, if you call logging.basicConfig() multiple times in the same program only the first invocation has an effect, and only if there weren't any handlers added to the root logger by other means. > > How do you see the end of the line starting with 'filename =...'? > > > Is it like: > for TEST:, 'TEST') > for DESIGN: , 'DESIGN') > > or did you put a full pathname in there? > > and, if you did put a full pathname in there (i.e. 'D:\TEMP\TEST' ), > did you also put the 'r' in front of it, like this: > , r'D:\TEMP\TEST') > > -- https://mail.python.org/mailman/listinfo/python-list
