Re: Python Events in 2017, Need your help.
Thank you, with your help, we have added events on the t-shirt. Now, Could you just add them on python.org/events ? Have a nice day, Stephane On 9 Jan 2017, at 10:54, Stephane Wirtel via Python-list wrote: Dear Community, For the PythonFOSDEM [1] on 4th and 5th February in Belgium, I would like to present some slides with the Python events around the World. Based on https://python.org/events, I have noted that there are missing events, for example: * PyCon Otto: Italy * PyCon UK: United Kingdom * PyCon CA: Canada * PyCon Ireland: Ireland * PyCon France: France Some of these events are not yet announced and I understand they are in the second semester, and thus, they don't know the location and the dates, excepted for PyCon Otto (April). In fact, I have noted that we know some big events in the Python community (for example: PyCon US and EuroPython) but do you know the others events, maybe the local event, PyCon IE, PyCon UK or PyCon IT. I like to know where there is a PyCon or a Django Conf or a PyData Event. In fact, I think we can help the Python Community if we submit all the events in https://python.org/events.

How to store properties
In Java you (can) use a properties file store configuration. What is the best way to do something like that in Python? I saw ConfigParser, but have the feeling that it is not really used.

If you only want to read the configuration, just use an ordinary file you import. For example config.py contains the lines: username=myuser server=myserver password=secret In your script: import config Now you can referenc all the variables via config., e.g. config.username Another method would be a dictionary for your config.

I think the relative simpleness of .INI files. If I was expecting end users to manipulate a config file, I would use ConfigParser. But 90% of the time, I just use another python module. For my purposes, there is no security risk to it. Due to its nature, Django also uses python modules to define configuration such as URL maps, etc. When I'm using GTK+, I would use the gsettings facilities of GTK+ to store and retrieve config variables.

I am afraid he means that it create mishmash in word document...
Dear accessnewbie I propose divide problem to smaller subproblems.
For example make python code as simple as possible (avoid python part if you
could! As Deborah wrote it is very probably not problem in python)
And try to explicitly try to write example text where is bold part.
#myBlurb = "My Favorite Cars -
My favorite cars are available at "
+ myText + ""
myBlurb = "My Favorite Cars -
My favorite cars are available at
my garage "
if it is still wrong try to make more and more similar text to: myBlurb =
"My Favorite Cars - My favorite cars are available at my garage"
I mean for example remove "" part etc.
Second - This is probably not your problem (unless you have special char in
your example myList) but if you could have xml spec chars in your input then
python could help. See example ->
>>> from xml.sax.saxutils import escape
>>> escape("< & >")
'< & >'
myBlurb = "My Favorite Cars - My favorite cars are available at " +
escape(myText) + "" # this is safer than your code!
I hope you understand why it is useful. :)

subprocess problem
The Problem with the subprocess code is: Using the sourcecode
functioning as normal.
The frozen app with cx_freeze on every platform just returns an empty result
Here is the code in short:
def get_path_pandoc():
settings = QSettings('Pandoc', 'PanConvert')
path_pandoc = settings.value('path_pandoc','')
if not os.path.isfile(path_pandoc):
if platform.system() == 'Darwin' or os.name == 'posix':
args = ['which', 'pandoc']
p = subprocess.Popen(
args,
stdin=subprocess.PIPE,
stdout=subprocess.PIPE)
path_pandoc =
str.rstrip(p.communicate(path_pandoc.encode('utf-8'))[0].decode('utf-8'))
The whole problematic code can be checked on
http://github.com/apaeffgen/panconvert
in source/converters/interface_pandoc.py
I debugged it with some QMessage-Boxes. I just know, that the returnd
result is empty.
I tried some stderr on this code also. But also the error message is empty.
Any hints what could be changed in the code, so it also works in the
frozen app?
At the moment i use python3.4 to 3.5 depending on the platform (Mac,

What does "which pandoc" say to you at a terminal prompt? The code above relies
on that returning you the path to the pandoc executable. If it is not in your
path then you will get an empty result.
Also, the "which" programme should have a zero exit status if it finds and
prints the path to pandoc, and a nonzero exit status otherwise? Find out what
exit status it returns. This is available from the "p" object after
communicate() returns. See the subprocess doco for details. The easy thing to
do is probably to call "p.check_returncode()" after communicate() returns.
Any hints what could be changed in the code, so it also works in the
frozen app?
What's a frozen app?
Maybe that is your problem: when you run the programme by hand it works, but in
this "forzen" state it doesn't.
The "which" command isn't magic. It searchs for commands by looking for
executables in the directories listed in the $PATH environment variable. Get
your program to print or display the value of "os.environ['PATH']" before
invoking "which". The difference may tell you something useful.
At the moment i use python3.4 to 3.5 depending on the platform (Mac,
Win, Linux)
Thank you for this information; many people forget to supply it.
P.S. Tried also some code with invoking the bash and afterwords the which
pandoc code. To know avail also
From a shell prompt (such as bash's prompt) issuing the command:
which pandoc
should print the executable path, _if_ your $PATH includes the right directory.
You can look at $PATH from the shell with the command:
echo $PATH
Do you know where pandoc normally resides on your system?

Decorator
Hi In python courses I read, it is explained that @decor def f(): pass is equivalent to: def f(): pass f = decor(f) But that's not always true. See this code class Temperature: def __init__(self): self.value = 0 # @property def celsius(self): return self.value celsius = property(celsius) # @celsius.setter def celsius(self, value):<-- overwrites previous celsius self.value = value celsius = celsius.setter(celsius) <-- error here When you define the setter function named celsius, it overwrites the previous property object also named celsius ... and it fails: celsius = celsius.setter(celsius) AttributeError: 'function' object has no attribute 'setter' any comment ? -- https://mail.python.org/mailman/listinfo/python-list

The difference is that the decorator line is evaluated before the
function is defined. Try this:
class Temperature:
def __init__(self):
self.value = 0
#@property
def celsius(self):
return self.value
celsius = property(celsius)
#@celsius.setter
_tmp = celsius.setter
def celsius(self, value):
self.value = value
celsius = _tmp(celsius)
del _tmp
Now it'll work.
(Actually, there are some other very minor subtleties; the name isn't
temporarily bound to the undecorated function prior to the decorator
being called. But in this case, it's simply an order of evaluation.)
In CPython (3.7 on Debian Linux, fwiw), the decorated function is
processed like this:
@celsius.setter
#_tmp = celsius.setter
def celsius(self, value):
self.value = value
#celsius = _tmp(celsius)
#del _tmp
11 28 LOAD_NAME5 (celsius)
30 LOAD_ATTR6 (setter)
32 LOAD_CONST 5 ()
34 LOAD_CONST 4
('Temperature..Temperature.celsius')
36 MAKE_FUNCTION0
38 CALL_FUNCTION1
40 STORE_NAME 5 (celsius)
In other words:
1) Evaluate "celsius.setter" and save that on the stack
2) Fetch up the compiled code for the undecorated function
3) Grab the name of the function (it's a constant)
4) Create a function. Don't save it anywhere yet, just put it on the stack.
5) Call the function from step 1, passing the function from step 4 as
a parameter.
6) Whatever it returns, save that under the name "celsius".
That's very detailed and nitty-gritty, but that's what really happens
when you use "@celsius.setter" in your code.
