[ANN] Movable Python 1.0.2
by Fuzzyman May 1, 2006

May 1, 2006

`Movable Python 1.0.2 <http://www.voidspace.org.uk/python/movpy/>`_ is now available. This release if for the Python 2.4 distribution of **Movable Python**, and is now available for `download <http://voidspace.tradebit.com/groups.php>`_. Features new to this release include : * Now built with Python 2.4.3. * Other updated modules include : - pywin32 build 208 - ctypes 0.9.9.6 - wxPython 2.6.3.2 - Firedrop 0.2.1 - ConfigObj 4.3.1 - Wax 0.3.33 * Scripts (and ``customize.py``) are now executed in a specific namespace, no more movpy cruft. * When entering interactive mode (``movpy -``), any *additional* command line arguments are passed to IPython. * ``imp.find_module`` has been fixed to work with modules contained in the zipfile. This fix doesn't write any temporary files, but ``imp.load_module`` has been patched to accept a ``StringIO`` instance. * Built in support for *matplotlib* interactive sessions. (``movpy - pylab``) * Verified that ``__future__`` statements are handled correctly. * New look documentation and website. To try the new `matplotlib <http://matplotlib.sourceforge.net/>`_ support, you'll need the `matplotlib files <http://www.voidspace.org.uk/matplotlib.zip>`_ in your ``lib/`` directory. You can then run the following at the command line : ``movpy.exe - -pylab`` This should drop you straight into a IPython session, with pylab enabled.

Passing events
by Wesley Brooks May 1, 2006

May 1, 2006

Dear Users, Is it possible to pass events such as keyboard, mouse, and joystick events to any software application and take screen shots? In this example I would like to be able to control a car racing game using python script. Is it difficult to recieve and create events from devices like the steering wheels and pedals? Thanks again in advance of any help. Yours Sincerely, Wesley Brooks

Converting floating point to string in non-scientific format
by Madhusudhanan Chandrasekaran May 1, 2006

May 1, 2006

Hi all: When I try to convert a float variable into string via repr() or str() function, i get the value as is, i.e '0.1e-7' in IEEE 754 format. Instead how can force the created string to represent the floating point in non-scientific fashion (non IEEE 754 format)? i.e something like 0.000000001 Thanks in advance for your help. -Madhu

critique this little script, if you like
by John Salerno May 1, 2006

May 1, 2006

# Create new subdomain directory (with subdirectories) in my 1and1 folder import os import sys subdirs = [r'\cgi-bin', r'\images', r'\styles'] #if len(sys.argv) == 1: # subdomain = raw_input('Enter subdomain name: ') #else: # subdomain = sys.argv[1] try: subdomain = sys.argv[1] except IndexError: subdomain = raw_input('Enter subdomain name: ') path = r'C:\Documents and Settings\John Salerno\My Documents\My Webs\1and1\johnjsalerno.com\\' + subdomain os.mkdir(path) for subdir in subdirs: os.mkdir(path + subdir) Just a simple script I wrote as an experiment, and it works nicely anyway. My two questions are these: 1. Like my other post, I'm wondering if it's okay to handle the ending backlash as I did in path 2. Between the if block or the try block, which is more Pythonic? The try block seems nicer because it doesn't have such an ugly-looking check to make.

ending a string with a backslash
by John Salerno May 1, 2006

May 1, 2006

I have this: subdomain = raw_input('Enter subdomain name: ') path = r'C:\Documents and Settings\John Salerno\My Documents\My Webs\1and1\johnjsalerno.com\' + subdomain Obviously the single backslash at the end of 'path' will cause a problem, and escaping it with a backslash seems to fix this problem, but how does escaping work when I already have it as a raw string? When I test it out and then print string, I get something like this: C:\Documents and Settings\John Salerno\My Documents\My Webs\1and1\johnjsalerno.com\\test But I don't see how this is valid, since all the backslashes are single (which is correct) except the last one. Somehow this still works when I tried to create the new directory -- os.mkdir(path) -- but I wasn't sure if this is the right way to go about it, or if there is some other, better way to handle the final backslash.

python and xulrunner
by joe.hrbek＠gmail.com May 1, 2006

May 1, 2006

Hi everyone, sorry, this post is a bit off topic. I posted this on a devel xul thread on the mozilla groups but didn't get a response. My hope is that some of you may have interest in this and have tried it yourself. I've been trying to get xulrunner compiled with python (in windows) but have been unsuccessful. I've been following this: <http://michaelthornhill.blogspot.com/2005/07/giving-python-legs-with-...>. I know it's a linux based tutorial, but the steps are generally the same aside from required os linkers/compilers - which i've obtained reading the standard mozilla compile instructions for windows. Has anyone else tried this and had luck with it? -j

Measure memory usage in Python
by Rune Strand May 1, 2006

May 1, 2006

Is there a way to measure how much memory a data structure use? For instance, what is the footprint of a particular list object like [0,1,2,3,4,5,6,7,8,9]?

Hi guys Tried searching for a solution to this, but the error message is so generic, that I could not get any meaningfull results. Anyways - errormessage: ---------------------------------------------------- TypeError: addFile() takes exactly 1 argument (2 given) ---------------------------------------------------- The script is run with two args "arg1" and "arg2": ---------------------------------------------------- import sys class KeyBase: def addFile(file): print "initialize the base with lines from this file" print "These are the args" print "Number of args %d" % len(sys.argv) print sys.argv print sys.version_info print sys.version f = sys.argv[1] print "f = '%s'" % f b = KeyBase() b.addFile(f) ---------------------------------------------------- The output - including error message (looks like stdout and stderr are a bit out of sync...): ---------------------------------------------------- These are the args Traceback (most recent call last): Number of args 3 ['C:\\home\\<.. bla bla snip ...>\\bin\\test.py', 'arg1', 'arg2'] (2, 4, 2, 'final', 0) 2.4.2 (#67, Oct 30 2005, 16:11:18) [MSC v.1310 32 bit (Intel)] f = 'arg1' File "C:\Program Files\ActiveState Komodo 3.5\lib\support\dbgp\pythonlib\dbgp\client.py", line 1806, in runMain self.dbg.runfile(debug_args[0], debug_args) File "C:\Program Files\ActiveState Komodo 3.5\lib\support\dbgp\pythonlib\dbgp\client.py", line 1529, in runfile h_execfile(file, args, module=main, tracer=self) File "C:\Program Files\ActiveState Komodo 3.5\lib\support\dbgp\pythonlib\dbgp\client.py", line 590, in __init__ execfile(file, globals, locals) File "C:\home\hbille\projects\bc4rom\bin\test.py", line 20, in __main__ b.addFile(f) TypeError: addFile() takes exactly 1 argument (2 given) ---------------------------------------------------- I'm running this inside ActiveState Komodo on WinXP.

Python based file format cracking
by Wesley Brooks May 1, 2006

May 1, 2006

Dear Users, Is there another tool that can examine an string for undefined repeating patterns? I'm aware of and have limited experience regular expressions which finds supplied patterns within a string. Yours Faithfully, Wesley Brooks
