  - by saltycrane

  In Python I can use the iterkeys() method to iterate over the keys of a dictionary. For example: mydict = {'a': [3,5,6,43,3,6,3,], 'b': [87,65,3,45,7,8], 'c': [34,57,8,9,9,2],} for k in mydict.iterkeys(): print k gives me: a c b How can I do something similar in Javascript?

  - by user210481

  Hi I have a MySQL server that I need access through a VPN. I use MySQLdb package to access MySQL server in Python.

• Executing JavaScript with Python without X.

  - by Thomas

  I want to parse a html-page that unfortunately requires JavaScript to show any content. In order to do so I use a small python-script that pulls the html-code of the page, but after that I have to execute the JavaScript in a DOM-context which seems pretty hard. To make it even harder I want to use it in a server environment that has no X11-server. Note: I already read about http://code.google.com/p/pywebkitgtk/ but it seems to need a X-server.

• Python: Split, strip, and join in one line

  - by PandemoniumSyndicate

  I'm curious if their is some python magic I may not know to accomplish a bit of frivolity given the line: csvData.append(','.join([line.split(":").strip() for x in L])) I'm attempting to split a line on :, trim whitespace around it, and join on , problem is, since the array is returned from line.split(":"), the for x in L #<== L doesn't exist! causes issues since I have no name for the array returned by line.split(":") So I'm curious if there is a sexy piece of syntax I could use to accomplish this in one shot? Cheers!

• Catching and outputting stderr at the same time with python's subprocess

  - by Mediocre Gopher

  (Using python 3.2 currently) I need to be able to: Run a command using subprocess Both stdout/stderr of that command need be printed to the terminal in real-time (it doesn't matter if they both come out on stdout or stderr or whatever At the same time, I need a way to know if the command printed anything to stderr (and preferably what it printed). I've played around with subprocess pipes as well as doing strange pipe redirects in bash, as well as using tee, but as of yet haven't found anything that would work. Is this something that's possible?
