[Tutor] Problems with creating XML-documents

2010-04-14 Thread Karjer Jdfjdf
I'm having problems with creating XML-documents, because I don't seem to write it to a document correctly. I have to write the document from a loop:     doc.write('\n')         for instance in query:        if doc != None:     text = str('\n' + \    ' ' +  st

[Tutor] difflib context to string-object?

2010-03-19 Thread Karjer Jdfjdf
With difflib.context_diff it is possible to write the context to files. difflib.context_diff(a, b[, fromfile][, tofile][, fromfiledate][, tofiledate][, n][, lineterm]) Is it also possible to do this to seperate string-objects instead of writing them to files? ___

Thank you all for the input. I've not been clear in my original question. For each value in the range (in example 10) I have to perform calculations with the values in the tuple (in example 3). This makes 30 calculations in total. In reality I have to do this for a much larger dataset (eg 1000

[Tutor] Problems with iterations and breaking loops.

2010-03-17 Thread Karjer Jdfjdf
I'm having problems with iterations and loops. So I'm curious about the best Python-way to do iterations of lists (in if, while etc statements) and breaking of loops. I have a list of tuples with 2 values. I want to perform calculations on all of these for each value in a range of values (e.g.

[Tutor] Proper way to use **kwargs?

2010-03-15 Thread Karjer Jdfjdf
I want to use **kwargs to check a list of conditions (if true do this, if false do nothing) besides required parameters ( in sample a and b).  Sometimes I want to add a Python object (in example a dictionary and a list). Below is my first **kwargs-brew. ###START def function_with_kwargs(a, b,

I brew this up. It works, but I think it will be slow with a long text and a big dictionary def searchWord(text, dictionary):     '''search for terms in dictionary(key) and retrieve value(keywords)'''     text = text.split()     w = []     for word in text:     if word in dictionary:

[Tutor] Use ZODB or Durus to store Python-objects?

2010-03-08 Thread Karjer Jdfjdf
I'm using pickle more often in my programs and now I store them as files. I want to store them in ZODB or Durus to prevent losing sight of where I store what pickled object. Which one is the best one to use? I've never worked with either one, so I would like to have some opinions. I want to ac
