x.strip( ) will create four parts.

Here's another way:

s.replace((, '').replace(), '').split('')[1::2]

But you should rather worry about correctness. Can '' occur inside the
parentheses and vice versa? Is there a way to escape ''? Can parentheses be
nested? Etc.
The example is not sufficient to specify the problem.

The right way to use config files
Folks,
I am not a computer scientist (just a scientist) and I'd like to ask
your opinion about a design problem I have. It's not that I can't get my
program to work, but rather that I have trouble to find an elegant
solution to the problem of passing information to my program's elements.
I have trouble to be clear in my request so my apologies for the long
text...
The tool I am developing is a classical data-analysis workflow. Ideally,
all the program's configurations are located in a single .cfg file which
I parse with ConfigObg. The file contains I/O informations
(path_to_input, path_to_output) as well as internal options
(use_this_function, dont_use_this_one, function1_paramx = y), etc...
Currently, my program is a super-object which is initialized once and
work schematically as follows:
main():
obj = init_superobj(config file)
obj.preprocess()
obj.process()
obj.write()
the superobj init routine parses the config files and reads the input data.
and a processing step can be, for example:
def process():
if self.configfile.as_bool('do_funcion1'):
params = config.parse_function1_params()
call_function1(self.data, params)
if self.configfile.as_bool('do_funcion2'):
params = config.parse_function2_params()
call_function2(self.data2, params)
The functions themselves do not know about the superobject or about the
configfile. They are standalone functions which take data and
parameters as input and produce output with it. I thought that the
standalone functions will be clearer and easier to maintain, since they
do not rely on some external data structure such as the configobj or
anything.
BUT, my problem is that several options really are universal options
to the program, such as the output directory for example. This
information (where to write their results) is given to most of the
functions as parameter.
So I had the idea to define a super-object which parses the config file
and input data and is given as a single parameter to the processing
functions, and the functions take the information they need from it.
This is tempting because there is no need for refactoring when I decide
to change something in the config, but I am afraid that the program may
become unmaintainable by someone else than myself. Another possibility
would be at least to give all the functions access to the configfile.
To get to the point: is it good practice to give all elements of a
program access to the configfile and if yes, how is it done properly?
I hope at least someone will understand what I mean ;-)
Cheers and thanks,
Fabien

That's not a bad idea, you could do that without embarrassment. A better technique, though, is to make use of modules as namespaces. Have one module of your application be responsible for the configuration of the application:: # app/config.py import configparser parser = configparser.ConfigParser() parser.read(app.conf) and import that module everywhere else that needs it:: # app/wibble.py from . import config def frobnicate(): do_something_with(config.foo) By using an imported module, the functions don't need to be parameterised by application-wide configuration; they can simply access the module from the global scope and thereby get access to that module's attributes. To get to the point: is it good practice to give all elements of a program access to the configfile and if yes, how is it done properly? There should be an encapsulation of the responsibility for parsing and organising the configuration options, and the rest of the application should access it only via that encapsulation. Putting that encapsuation in a module is an appropriately Pythonic technique. -- \ “Now Maggie, I’ll be watching you too, in case God is busy | `\ creating tornadoes or not existing.” —Homer, _The Simpsons_ | _o__) | Ben Finney -- https://mail.python.org/mailman/listinfo/python-list

They need to be led in small steps towards basic knowledge. 2) People who are (at least somewhat) experienced programmers, and are learning Python as a second language. Their experiential background is limited to one way of doing things (i.e. the Java way, or the PHP way, or whatever language way they learned first). They mostly should be shown how translate the things they already know into familiar feeling constructs. You already know how to write a loop, this is how we do it in Python. You already know how build a data structure that maps keys to values, this is how we do it in Python. Only after they've become comfortable with that, should they start exploring the really cool features of Python. 3) People who already know many languages, and are learning Python as their n-th. These folks have seen multiple ways of doing things, and can understand concepts at a higher level. Oh, Python dicts are more like C++ STL maps than PHP arrays. Oh, variables have function scope and don't have to be explicitly declared. Oh, RAII is spelled with in this language. Oh, functions are first-class objects, but code blocks are not. 4) People who are already proficient Python programmers and are looking to explore deeper topics.

I see. But then this is also true for parameters, right? And yet we

Let's say my configfile looks like this:
-
### app/config.cfg
# General params
output_dir = '..'
input_file = '..'
# Func 1 params
[func1]
enable = True
threshold = 0.1
maxite = 1

-
### app/myconfig.py
import ConfigObj
parser = obj() # parser will be instanciated by initialize
def initialize(cfgfile=None):
global parser
parser = ConfigObj(cfgfile, file_error=True)
-
My main program could look like this:
-
### app/mainprogram_1.py
import myconfig
def func1():
# the params are in the cfg
threshold = myconfig.parser['func1'].as_float('threshold')
maxite = myconfig.parser['func1'].as_long('maxite')
# dummy operations
score = 100.
ite = 1
while (score threshold) and (ite maxite):
score /= 10
ite += 1
# dummy return
return score
def main():
myconfig.initialize(sys.argv[1])
if myconfig.parser['func1'].as_bool('enable'):
results = func1()
if __name__ == '__main__':
main()
-
Or like this:
-
### app/mainprogram_2.py
import myconfig
def func1(threshold=None, maxite=None):
# dummy operations
score = 100.
ite = 1
while (score threshold) and (ite maxite):

# dummy return

def main():
myconfig.initialize(sys.argv[1])
if myconfig.parser['func1'].as_bool('enable'):
# the params are in the cfg
threshold = myconfig.parser['func1'].as_float('threshold')
maxite = myconfig.parser['func1'].as_long('maxite')
results = func1(threshold=threshold, maxite=maxite)
if __name__ == '__main__':
main()
-
In this case, program2 is easier to test/understand, but if the
parameters become numerous it could be a pain...
As always, I guess I'l have to decide on a case by case basis what is best.

The advantage of TDD is that it forces one to make code testable as you
do. Old code may not be designed to be so easily testable, as I have
learned trying to add tests to idlelib. For the above, I would consider
def func1_algo(threshhold, maxite): # possible separte file
score = 100.
ite = 1
while (score threshold) and (ite maxite):
score /= 10
ite += 1
return score
def func1(): # interface wrapper
threshold = myconfig.parser['func1'].as_float('threshold')
maxite = myconfig.parser['func1'].as_long('maxite')
return func1_algo(threshhold, maxite)
This is a slight bit of extra work, but now you can separately test (and
modify) the algorithm and the interfacing. Testing the algorithm is
easy, which encourages testing multiple i/o pairs.
for in, out in iopairs:
assert func1_algo(in) == out # or self.assertEqual, or ...
(or close enough for float outputs)
As for the interfacing: you can write and read multiple versions of
config.cfg (relatively slow), use something like unittest.mock to mock
the myconfig module, or write something fairly simple (py3 code).
class Entry(dict):
def as_bool(self, name):
s = self[name]
return True if s == 'True' else False if s == 'False' else None
def as_int(self, name):
return int(self[name])
as_long = as_int
def as_float(self, name):
return float(self[name])
class Config(object):
def initialize(self, argv):
pass
myconfig = Config() # a module is like a singleton class
myconfig.initialize('a') # test that does not raise
# In use for testing, uncomment the following two lines
# import mainprogram_1.py as mp1
# mp1.myconfig = myconfig
f1_cfg = Entry({
'enable': 'True',
'threshold': '0.1',
'maxite': '1',
})
myconfig.parser = {'func1': f1_cfg}
print(myconfig.parser['func1'].as_float('threshold') == 0.1)
print(myconfig.parser['func1'].as_long('maxite') == 1)
print(myconfig.parser['func1'].as_bool('enable') == True)
f1_cfg['maxite'] = 5
print(myconfig.parser['func1'].as_int('maxite') == 5)
# prints True 4 times
Notice that you inject the mock myconfig into the tested module just
one. After that, you can change anything within parser or replace parser
with a new dict.
Or like this:
-
### app/mainprogram_2.py
import myconfig
def func1(threshold=None, maxite=None):
These should not have defaults; avoid extra work!
# dummy operations
score = 100.
ite = 1
while (score threshold) and (ite maxite):
score /= 10
ite += 1
# dummy return
return score
def main():
myconfig.initialize(sys.argv[1])
if myconfig.parser['func1'].as_bool('enable'):
# the params are in the cfg
threshold = myconfig.parser['func1'].as_float('threshold')
maxite = myconfig.parser['func1'].as_long('maxite')
results = func1(threshold=threshold, maxite=maxite)
if __name__ == '__main__':
main()
-
In this case, program2 is easier to test/understand, but if the
parameters become numerous it could be a pain...
This is equivalent to what i wrote except for putting the wrapper inline
in main(). Testing is the same for either.

Fwd: How to draw a map using python
To kind whom it may concern: I want to draw a map using python, not really a map with full information, just a get together of a series of small shapes to reflect land use. The data is like below 1 2 2 3 3 22 3 3 1 1 21 1 1 1 3 33 3 3 3 4 1 Each number represents one land use type. and their positions in the matrix are their coordinates. I used VBA to do that before, the whole map consists many small square shapes representing land use, but since the data was so large, it took a long time to generate the map, also delete the map. My question are : 1. I wonder in python, is there any more fast way to generate this kind of map, as a whole, not a series of shapes, i think that would be faster？？ 2. I have tried using contourf, as below, but it says out of bounds for axis 1, but actually, I printed X,Y and cordi, they have the same shape, why still out of bounds? 1. y = np.arange(0, 4 , 1) x = np.arange(0, 6 , 1) X,Y = np.meshgrid(x,y) # cordi is the matrix containing all the data# pyplot is imported before plt.contourf(X,Y, Cordi[X,Y], 8, alpha=.75, cmap='jet') 3. Some kind person has suggested me to use imshow to plot. I checked the explanation of imshow, it deals more about images not plots, and it needs a 3D array to plot, in which for each pixel it needs 3 values to show the color. I also tried, not so acceptable. The interfaces of each color are so vague, and besides, when the data is large, it just failed to present. So, if I use imshow, could I have some way to avoid those two problems? Thank you very much for answering! -- https://mail.python.org/mailman/listinfo/python-list

[issue21725] RFC 6531 (SMTPUTF8) support in smtpd
R. David Murray added the comment:
I tweaked your additions. Instead of trying to strip out the 'b' to make
things look pretty, I think it is better to print them and thus make it
explicit when we are dealing with binary data and when we are dealing with
strings. It also clues the user in to the fact that the escaping inside the
string is that used for bytes display, as opposed to string display. I also
expanded the tests to include headers so that the 'X-Peer' header addition
would get tested. This reveals a bug; whether it is in the tests or the code I
don't know: the value of self.peer in the process_ methods is 'peer', not the
expected ('b', 0). If you can look in to this issue it would be great.
That looks like the last issue that needs to be addressed before commit.
(Oh, yeah, and there was a bug in the original process_message code...it was
printing an extra blank line at the end of the message text if there was, as
there should be, a newline at the end of the message...I fixed that by
switching to splitlines instead of split.)

[issue21725] RFC 6531 (SMTPUTF8) support in smtpd
Milan Oberkirch added the comment:
I think that the peer arg is supposed to be set to the address of the peer
connecting to our server.
The value 'peer' comes from test/mock_socket.py:105 and is the best answer we
can get for mock_sock.getpeername() because there is no real client when
directly writing into the socket. ('b', 0) would be the address of the remote
server.

The reason I suspect it's the missing runtime check that's causing the py problem is because (as far as I am aware), Jinja2 generates AST constructs directly and compiles those, and thus may be relying on the runtime check. It's just a theory, though. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21591 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22174] property doc fixes
Raymond Hettinger added the comment: Also, please don't add the extra whitespace to the docstring. It is intentionally compact because of the differing needs of various IDEs and help utlities. -- assignee: docs@python - rhettinger nosy: +rhettinger ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22174 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue22174] property doc fixes
diana added the comment: This whitespace? Or did you mean something else? class C: def __init__(self): self._x = None def getx(self): return self._x def setx(self, value): self._x = value def delx(self): del self._x x = property(getx, setx, delx, I'm the 'x' property.) versus: class C: def __init__(self): self._x = None def getx(self): return self._x def setx(self, value): self._x = value def delx(self): del self._x x = property(getx, setx, delx, I'm the 'x' property.) I added it to be consistent with the rest of the code snippets in the property docs. For example: class C: def __init__(self): self._x = None @property def x(self): I'm the 'x' property. return self._x @x.setter def x(self, value): self._x = value @x.deleter def x(self): del self._x Of the three code snippets in the property docs, that first one is the only one that doesn't have whitespace between the methods. That first code snippet also has inconsistent whitespace within itself (__init__ vs the rest of methods). Anyhoo, that was my reasoning, but that's largely beside the point. I will happily drop it and leave it as-is. What really prompted me to submit a patch was this paragraph: If given, doc will be the docstring of the property attribute. Otherwise, the property will copy fget‘s docstring (if it exists). This makes it possible to create read-only properties easily using property() as a decorator: I now understand the original intent, but I don't think it's clear as-is. I also find it a bit odd that 'fget', 'fset', 'fdel' are all defined in the first sentence of the docs, but 'doc' isn't. It then launches into an example that uses 'doc' (still as of yet undefined), before defining 'doc' later on in the read-only properties part. I'll think on it a bit some more -- feel free to close this in the mean time. It's been this way for a better part of a decade, so perhaps it's just me ;) Cheers, --diana -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22174 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
