  Suppose I have a python object x and a string s, how do I set the attribute s on x? So: >>> x = SomeObject() >>> attr = 'myAttr' >>> # magic goes here >>> x.myAttr 'magic' What's the magic? The goal of this, incidentally, is to cache calls to x.__getattr__().

• How should I grab pairs from a list in python?

  - by tomaski

  Say I have a list that looks like this: ['item1', 'item2', 'item3', 'item4', 'item5', 'item6', 'item7', 'item8', 'item9', 'item10'] Using Python, how would I grab pairs from it, where each item is included in a pair with both the item before and after it? ['item1', 'item2'] ['item2', 'item3'] ['item3', 'item4'] ['item4', 'item5'] ['item5', 'item6'] ['item6', 'item7'] ['item7', 'item8'] ['item8', 'item9'] ['item9', 'item10'] Seems like something i could hack together, but I'm wondering if someone has an elegant solution they've used before?

• Do you use Python mostly for its functional or object-oriented features?

  - by Eric

  I see what seems like a majority of Python developers on StackOverflow endorsing the use of concise functional tools like lambdas, maps, filters, etc., while others say their code is clearer and more maintainable by not using them. What is your preference? Also, if you are a die-hard functional programmer or hardcore into OO, what other specific programming practices do you use that you think are best for your style? Thanks in advance for your opinions!

• Show default value for editing on Python input possible?

  - by kircheis

  Is it possible for python to accept input like this: Folder name: Download But instead of the user typing Download it is already there as a initial value. If the user wants to edit it as Downloads all he has to do is add a 's' and press enter. Using normal input command: folder=input('Folder name: ') all I can get is a blank prompt: Folder name: Is there a simple way to do this that I'm missing?

• Can python code (say if I used djangno) be obfuscated to the same 'level' as c#/java?

  - by Blankman

  If I obfuscated python code, would it provide the same level of 'security' as c#/java obfuscating? i.e it makes things a little hard, but really you can still reverse engineer if you really wanted to, its just a bit cryptic.

• Can I upload an object in memory to FTP using Python?

  - by fsckin

  Here's what I'm doing now: mysock = urllib.urlopen('http://localhost/image.jpg') fileToSave = mysock.read() oFile = open(r"C:\image.jpg",'wb') oFile.write(fileToSave) oFile.close f=file('image.jpg','rb') ftp.storbinary('STOR '+os.path.basename('image.jpg'),f) os.remove('image.jpg') Writing files to disk and then imediately deleting them seems like extra work on the system that should be avoided.

• Take user input and put it into a file in Python?

  - by Galilsnap

  I must have skipped a page or two by accident during my PDF Tutorials on Python commands and arguments, because I somehow cannot find a way to take user input and shove it into a file. Don't tell me to try and find solutions online, because I did. None made sense to me.

• How can I have my python file show its mercurial tag or revision as the module version?

  - by Chris R

  I'd like to add a --version command line option to my python application that will show the right version depending on the tagged status of the command: If the file comes from a version whose short hex ID was abcdef01 that was tagged TAG, --version should show this: MyApp Version TAG (abcdef01) If the file comes from the tip, --version should show this: MyApp (tip) If the file comes from an arbitrary, untagged revision abcdef02, --version should show this: MyApp (development, abcdef02) Is this possible? If so, how?

• Is there a good Python library that can parse C++?

  - by csbrooks

  Google didn't turn up anything that seemed relevant. I have a bunch of existing, working C++ code, and I'd like to use python to crawl through it and figure out relationships between classes, etc. EDIT: Just wanted to point out: I don't think I need or want to parse every bit of C++; I just need something smart enough to pick up on class, function and member variable declarations, and to skip over function definitions.

• html/javascript automaticly getting link from submit button (maybe automating with python?)

  - by user317955

  I have a website where I have to click a submit button on a form. This gives me a link. I know the link is made up with the paramter that is passed through a hidden value. I was wondering if I could make a python script or something else that would go to the website and click some buttons returning the link that the submit button generates, if so how could I pass the extra parameter that influences the creation of the link? thanks in advance.

• Is there an easy way to "append()" two dictionaries together in Python?

  - by digitaldreamer

  If I have two dictionaries I'd like to combine in Python, i.e. a = {'1': 1, '2': 2} b = {'3': 3, '4': 4} If I run update on them it reorders the list: a.update(b) {'1': 1, '3': 3, '2': 2, '4': 4} when what I really want is attach "b" to the end of "a": {'1': 1, '2': 2, '3': 3, '4': 4} Is there an easy way to attach "b" to the end of "a" without having to manually combine them like so: for key in b: a[key]=b[key] Something like += or append() would be ideal, but of course neither works on dictionaries.
