[Tutor] Generating XML using Python
hi, i'm using python to generate xml with elementtree api. and i'm getting error when opening the output xml. it doesnt give error when running. i also tried to use python to output to a text file and it works without any error. Pls advise me how i can rectify the error when opening the output xml. attached is my code, output in text file and output in xml. thanks tcl p/s: i sent earlier email but got bounced email so sending out again. import elementtree.ElementTree as ET lspeed=2 tspeed=3 f=open(out.txt, w) for port in range(1,9): print Port %d %port root = ET.Element(Test) f.write(Port %d\n %port) head1 = ET.SubElement(root, Default_Config, Port=str(port)) print Link speed: %d %lspeed f.write(Link speed: %d\n %lspeed) title = ET.SubElement(head1, LINK) title.text = str(lspeed) print Target speed: %d %tspeed f.write(Target speed: %d\n %tspeed) title = ET.SubElement(head1, Target Speed) title.text = str(tspeed) tree = ET.ElementTree(root) tree.write(C:\\Python25\\myscript\\cmm\\port1.xml) f.close() port1.xml Description: Binary data Port 1 Link speed: 2 Target speed: 3 Port 2 Link speed: 2 Target speed: 3 Port 3 Link speed: 2 Target speed: 3 Port 4 Link speed: 2 Target speed: 3 Port 5 Link speed: 2 Target speed: 3 Port 6 Link speed: 2 Target speed: 3 Port 7 Link speed: 2 Target speed: 3 Port 8 Link speed: 2 Target speed: 3 ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] How to design the structure of multi-steps(and substeps)scripts
leechau char...@sohu.com wrote def step1: local_var1 = ... # some other variable definitions for step1 def substep11: pass # more substeps ... global_var1 = ... # more global var definitions... if step1.return_success: step2 Since this is obviously pseudo code I'll assume the real code has fixed the synrax issues. steps in one module, where one step corresponding to one funciton and one substep corresponding to one nested function. While that may seem logical it does limit reuse of the subfunctions. Do these subfunctions look very similar? Could the be written more generically - perhaps using some parameters to deal with differences? If so take them outside the steps. Then define your steps as tables of functions step1 = [substep1,substep2,substep3] and call using a loop: for step in step1: step() maintain this script because of totally 1000+ lines of code. Thats getting close to the biggest I like my modules to be but not huge. The size is not the problem - after all thats what search is for in the editor! :-) when I manipulate different projects with this script I need to modify the value of some variables and detailed task logic. Obviously it's a dirty work to modify the source code directly for different projects. If you are reusing then break the modules down to the size of the unit of reuse. So if you only use a single step then make each step a module. BUt if you reuse the entire group then keep it as one. If I should put the default value of a variable and high level task logic in a abstract class, and define specific value and detailed task logic in concrete subclass? That would be good to get rid of the globals at least and enable different projects to modify the instance values for their own purposes. any design patterns available for this kind of multi-steps scripts? I'd definitely consider a data driven approach as suggested above, but a lot depends on how complex the real logic is inside the steps. If it can be simplified to little more than a sequence of substeps and those substeps can be generic then a table driven style will greatly simplify the code. Another pattern that is likely to apply is a state machine, either implemented using state classes or as a table. But without knowlege of the detail of the real code we cannot make definite recommendations.

I thought python would be a great way to do so since I know a little python but not fortran. So, my plan was to read in each line, and then at a certain line number, write out the changed code. A short snippet is as follows: dest= open( f1, w ) source= open( f2, r ) for line in source: if X: dest.write( newline + \n ) else: dest.write( line ) dest.close() source.close() The problem I am having is with hidden/invisible character. In the fortran code, there are line indents which are denoted with an invisible character ^I. When I write with python, there is no ^I at the beginning of the line and the fortran code no longer compiles. I know how to put in the invisible line return character (\n), but how can I put in other invisible characters? I think you could avoid entirely this problem by using the binary option in the open function: dest= open( f1, wb ) source= open( f2, rb ) This way, each read and each write you perform will take into account all kinds of characters, and so your written lines will be identical to those you read. If the problem was only with the newline lines, then Steven's answer has already solved your problem. Hope that helps Francesco - Nessun virus nel messaggio.

[Tutor] A Dictionary question
Hi Everyone,
I am a super beginner and am little muddled right now. So I apologize for the
low level question but I am trying to write a function that will return a
dictionary of a given list of strings containing two coordinates separated by a
space with the first numbers as a key and the second numbers as its
corresponding value. I thought maybe a set might be helpful but that didn't
seem to work at all. I am pretty much as confused as they come and any help
would be very much appreciated. Thank you so much for your time.

That's what this list is for, so you're asking in the right place!
but I am trying to write a function that will return a dictionary of a

It's always helpful to give example input and output, as well as show us
what you've done so far.It's *also* a good idea to tell us what your end
goal is, rather than just I have this data and I want to manipulate it
thus, because oft times it turns out that there are much better ways to
accomplish the end goal.
Here's what it sounds like you say you want to do:
line_xy = ['1 1', '2 2', '3 3', '4 4'] # Coordinates along the line y = x
def dictify_list(coords):
returnval = {}
for pair in coords:
x, y = pair.split()
returnval[x] = y
return returnval
dictify_list(line_xy) # produces {'1':'1', '3':'3', '2':'2', '4':'4'} or
some equivalent dict - they're non-ordered
But I can't think of a time that I would want data collected this way. My
guess is that unless you have a super special case, you don't really need
the data that way either.

Wayne

It will help if you give us an example of what your input data is, and
what you expect to get for your result. I'm going to try to guess.
I think your input data might look like this:
data = [1 2, 4 5, 23 42]
and you want to return a dictionary like:
{1: 2, 4: 5, 23: 42}
Am I close?
This sounds like homework, and our policy is not to solve homework for
people, but to guide them into solving it themselves. So here are some
hints. Please feel free to show us the code you are using if you have
any problems.
You will need to have a dict ready to store keys and values in, and then
you need to look at each string in the data list one at a time:
result = {} # This is an empty dictionary.
for s in data:
# Process the variable s each time.
print(s)
Since s is a string that looks like two numbers separated by a space,
processing the string needs two tasks: first you have to split the
string into the two parts, and then you have to turn each part from a
string into an actual number.
(Remember that in Python, 42 is not a number, it is just a string that
looks like a number.)
There are two functions that are useful for that: one is a string
method, and one is a proper function. Here are some examples to show
them in action:
# Splitting a string into two pieces:
s = 1234 5678
s.split()
['1234', '5678']
# Converting a string into a proper number:
a = 987
int(a)
987
The split method is especially useful when you use assignment to create
two variables at once:
s = 1234 5678
a, b = s.split()
a
'1234'
b
'5678'
int(a)
1234
Lastly, do you know how to store objects into a dictionary? You need two
pieces, a key and a value:
d = {} # Empty dict.
key = dinner
value = pizza
d[key] = value
print What's for dinner?, d[dinner]
What's for dinner? pizza
Only in your case, rather than storing strings in the dict, you want to
store numbers created by int(). So now you have to put all the pieces
together into one piece of code:
(1) Create an empty dict.
(2) Loop over the individual strings in the input list.
(3) For each string, split it into two pieces.
(4) Convert each piece into an int (integer).
(5) Store the first piece in the dict as the key, and the second piece
as the value.
Good luck!

[Tutor] ImportError: No module named wdmmgext.load
Hi,
Thanks Emile van Sebille for answering my last question.
I'm now testing my imported data and I get 21 errors (see attached). The
majority sounds like:
from wdmmgext.load import uganda
ImportError: No module named wdmmgext.load
I've searched the files that use this module. Attached is an example file.
I see 2 more errors;
1) that the file 'ukgov-finances-cra/cra_2009_db.csv' does not exist.
2) SolrException: HTTP code=404, reason=Not Found
Maybe both are due to the wdmmgext.load error, so I'll ignore this for now and
first try to find answer to my first question.
Thanks in advance for the help!

Re: [Tutor] Running python on windows
At least in my case it was about simplicity. If it was a simple matter of using a base python program, that would be one thing, but the last program i distributed here at work used pygtk as it's GUI (which at the time required four different packages, I believe they have consolidated this down to one, thank god), a month / date arithmetic module a few other modules I can't remember off the top of my head. It doesn't make sense to say, go here, install this, ok, now drop this in this folder, ok now drop this in that folder, ok now open your command prompt and type this string of words. But don't typo while your at it. It took all of five minutes to learn how to use CX enough so I could freeze something and send it around to people here to use. It would have taken 30 minutes to explain how to install each component to people who just want stuff to work.

[Tutor] Import multiple lines of text into a variable
I'm not sure how to do this. I'm reading lines in from a text file.
When I reach the string notes:, I want to assign the remainder of
the text file to a single variable (line breaks and all):
text
moretext
moretext
notes:
This is the stuff I want in my variable.
And this line should be included too.
Also this one.
So right now my code looks something like this:
for line in open('myfile','r'):
if line.startswith('notes'):
## Assign rest of file to variable
Is there an easy way to do this? Or do I need to read the entire file
as a string first and carve it up from there instead?

Re: [Tutor] Converting files
I use Openoffice and it has an option to export your files to .pdf and lots of other file formats. It's a free download - and has all the usual Office applications... Search for 'OpenOffice' online.

Seems like an elegant solution to me, as long as the file fits available
memory. There will be 2 copies of the file after the split.
Another way:
textFile = open('myfile','r')
for line in textFile:
if line.startswith('notes'):
notes = textFile.read()

Re: [Tutor] Running python on windows
At least in my case it was about simplicity. If it was a simple matter of using a base python program, that would be one thing, but the last program i distributed here at work used pygtk as it's GUI Valid comment although its not much more work to build a custom installer that installs Python plus all the other libs. And checks that they aren't already there first... However due to the incompatibility issues around v3 I'm much less anti-packages than I used to be. But I do think the reluctance to install Python is not a valid reason, it's not much different to installing a JVM for java. It doesn't make sense to say, go here, install this, ok, now drop this in this folder, ok now drop this in that folder, ok now open your command prompt and type this string Agreed, we need to package our apps so the user doesn't need to do this. But that doesn't necessariily mean creating a packed exe. But sadly that usually means using a third party installer, and the best of those are all commercial so it costs $$$.

The best, yes, but the likes of InnoSetup or NSIS are free, and fairly reasonable to use. Once I graduate, I suspect it won't be long before I've built a few templates around one or the other specifically designed for Python. I'm not aware if anyone else has done such things. -Wayne ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

hi Peter,
thanks for your reply. seems that xml doesnt accept a space in between.
anyway, the output generated is:

Default_ConfigPort=*8*
** LINK*2*/LINK
** Target_Speed*3*/Target_Speed

it overwrites every time the port number is incremented and only
capture the last iteration number. how can i modify it to capture all
the iteration? for eg:
Port 1
Link speed: 2
Target speed: 3
Port 2
Link speed: 2
Target speed: 3
Port 3
Link speed: 2
Target speed: 3
Port 4
Link speed: 2

Target speed: 3
Port 6
Link speed: 2
Target speed: 3
Port 7
Link speed: 2
Target speed: 3
Port 8
Link speed: 2
Target speed: 3
thanks

Sorry for the error, must remove ' Port' in iter() this example use std
lib xml.etree.ElementTree doctree_instance obtain through parse()
method from ElementTree and it works with infinite tag 'default_Config'
list:
for config in doctree_instance.iter('Default_Config'):
link = config.find('LINK')
target = config.find('Target_Speed')
print('Port ', config.attrib['Port'])
print('Link speed:', link.text)

I should have clarified, the if line.startswith part was used to
break out of the previous for loop, which was used to import the
other, shorter strings.
