Simple Object assignment giving me errors

[Nir]

This is from the book 'dive into python'. I am trying to define jeez as being 
an instance of FileInfo.

class UserDict(object):
def __init__(self, dict = None):
self.data = {}
if dict is not None: self.update(dict)

class FileInfo(UserDict):
def __init__(self, filename=None):
UserDict.__init__(self)
self["name"] = filename


jeez = FileInfo("yo")




I get a TypeError: 'FileInfo' object doesn't support item assignment .

Am I missing something?

Re: Simple Object assignment giving me errors

[Nir]

Those two classes are from this code here(pasted below). Quite frankly, I don't 
understand this code. 

Also, UserDict is a built in module. I just typed it out so as to give 
reference or any clue as to why I cant instantiate jeez.

==

"""Framework for getting filetype-specific metadata.

Instantiate appropriate class with filename.  Returned object acts like a
dictionary, with key-value pairs for each piece of metadata.
import fileinfo
info = fileinfo.MP3FileInfo("/music/ap/mahadeva.mp3")
print "\\n".join(["%s=%s" % (k, v) for k, v in info.items()])

Or use listDirectory function to get info on all files in a directory.
for info in fileinfo.listDirectory("/music/ap/", [".mp3"]):
...

Framework can be extended by adding classes for particular file types, e.g.
HTMLFileInfo, MPGFileInfo, DOCFileInfo.  Each class is completely responsible 
for
parsing its files appropriately; see MP3FileInfo for example.

This program is part of "Dive Into Python", a free Python book for
experienced programmers.  Visit http://diveintopython.org/ for the

If this makes sense to you, great. I am trying to break it down so that I can 
make sense of it. As you mentioned self["name"] = filename doesn't work unless 
I built a class to handle it. I guess my question then, is how is the class 
handling it in this code? If you can show me by stripping it down to the bare 
minimum or write an example that would be awesome.

Why is the interpreter is returning a 'reference'?

[Nir]

>>> k = ['hi','boss']
>>>
>>> k
['hi', 'boss']
>>> k= [s.upper for s in k]
>>> k
[, ]

Why doesn't the python interpreter just return
['HI, 'BOSS'] ?

This isn't a big deal, but I am just curious as to why it does this.

Winpdb may sound to you as windows specific but it actually googles up
as platform independent. Those of you who dare work with a bunch of
separate development tools (oh, the terror, ugh...) instead of an IDE
will find it to be one of the best Python debuggers around.

With Winpdb you can pause (break into) and inspect the state of the

It does not check a different variable.
You can open a Python session and try the following:

Python 2.5.1 (r251:54863, Oct  5 2007, 13:36:32)
[GCC 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> a = True
>>> id(a)
135527852
>>> a = False
>>> id(a)
135527840

The problem is that the waiter is locked waiting for new food and
never looks at the variable.
You should add hot_food.release() after you set the keep running flag
to False.

Re: Cannot use Winpdb (or PyDev) to trace embedded Python script in MSVC++ application - ImportError: No module named _socket

[Nir]

You seem to be having a problem with the import path of the embedded
interpreter. I suppose the embedded interpreter includes some modules
in a particular folder and _socket is not one of them. For the sake of
debugging try adding the c:\python25\lib path to the sys.path variable
of the interpreter before attempting to import rpdb2.

Does this work?

Re: Cannot use Winpdb (or PyDev) to trace embedded Python script in MSVC++ application - ImportError: No module named _socket

[Nir]

Can you check another hypothesis?

I currently do not have a Python installation to verify this but if my
memory does not fail me there is a DLL library somewhere under c:
\python25 and _socket might be there as well. Copy any DLLs you find
there to the same folder as your embedded interpreter DLL and see if
the problem is resolved.

Re: debugger on system with Python 2 and 3

[Nir]

rpdb2 should be compatible with Python 3.x.
And once you start a debugging session with rpdb2 (running with Python
3.x)
you can attach to it from a winpdb instance (running with Python 2.x)

Packaging multiple wheels in the same package

[Nir Cohen]

Hey all,

As part of working on Cloudify (http://github.com/cloudify-cosmo) we've had to 
provide a way for customers to install our plugins in an environment where PyPI 
isn't accessible. These plugins are sets of Python packages which necessarily 
depend on one another (i.e. a regular python package with dependencies).

We decided that we want to package sets of wheels together created or 
downloaded by `pip wheel`, add relevant metadata, package them together into a 
single archive (tar.gz or zip) and use the same tool which packs them up to 
install them later on, on the destination hosts.

We came up with a tool (http://github.com/cloudify-cosmo/wagon) to do just that 
and that's what we currently use to create and install our plugins.

While wheel solves the problem of generating wheels, there is no single, 
standard method for taking an entire set of dependencies packaged in a single 
location and installing them in a different location.

We thought it would be a good idea to propose a PEP for that and wanted to get 
your feedback before we start writing the proposal.

The logic behind the PEP is that there's a standard for creating a single 
python package and we would like to propose a layer above it to package 
multiple python packages either for offline environments or any other 
requirement a user may have.

We're currently working on a new rearchitected version of that tool to make it 
more pythonic and clean but the base stays the same.


We would greatly appreciate your feedback on this.

Thanks!


P.S. We encourage you to take a look at the repo (see the `rearchitecture` 
branch) and read the README.

Sorry to bump this up.. but I'm not sure exactly how I should go about getting 
as much feedback as possible on this. Any suggestions?

A bioinformatics module similar to DEseq in R

[nir . yakovi1]

Hi!
is there a Python module equivalent\as similar as possible to 'DEseq' in R?
It's just that my team's (many) scripts use it, and to start modifying them all 
to support some different bioinformatics module would be a nightmare.
Thanks!

Hello Len,

You should try the #python IRC room.
It is always very active and helpful.

sys.path and unicode folder names

[Nir Aides]

Hello,

Is there a solution or a work around for the sys.path problem with 
unicode folder names on Windows XP?

I need to be able to import modules from a folder with a non-ascii name.

Thanks,
Nir

Re: sys.path and unicode folder names

[Nir Aides]

I can not restrict the name to CP_ACP.
I am interested in the general case of Unicode.
Windows XP is a native Unicode OS.

Re: sys.path and unicode folder names

[Nir Aides]

Actually, I already managed to make a Patch for this problem.
I will post it soon on my website and in this group.

But I find it strange that this problem even exists, and that I could 
not find any workarounds on the Internet.

Re: sys.path and unicode folder names

[Nir Aides]

If few people use file names not in their respective CP_ACP as you say, 
why did Microsoft bother to make Windows XP a unicode OS?
It does not make any sense.

The existence of such bugs is the source of the problem itself.

It is because of this situation that people in non-English speaking 
countries prefer to install English Windows XP. After all why should 
they get all messed up with incompatible software?

And from my experience a considerable percent of these 
stay-on-the-safe-side users have their CP_ACP pages setup incorrectly.

My software installs per-user Python modules in a sub-folder of the 
User's Application-Data folder. The software itself resides under 
Program-Files. The User's Application-Data folder will contain unicode 
characters if the User's account name contains unicode characters.

You can argue that the design is good or wrong or can be altered to work 
around the problem, but the fact remains:

Python is Broken.

They don't refuse. You assume they actually know about its existence. I 
think that in  most cases they are not aware of that thing. Sometimes 
they call their 10 year old neighbors to fix their computer if they are 
tired of seeing garbage on their screen instead of readable characters, 
but their computer usually crashes under the heavy load of dozens of 
viruses and spy-ware long before that kid neighbor gets a chance to look 
at it anyway.

Tkinter and Windows XP themes (via manifest files)

[Nir Aides]

Hello,

How do I make Tkinter use windows XP themes?
ordinary root Tkinter windows ignore the manifest file (which is placed 
by wxPython for the same purpose)

but message dialogs popped with tkMessageBox.Message do use the Windows 
Theme, so it should be possible.

Does anyone has a clue?
Thanks,
Nir

tkinter and threads

Hello,

In Tkinter, is it safe to call widget.after(time, callback) from another

tracing crash

[Nir Aides]

Hi,

I am facing a strange problem.
I will appreciate an explanation and a work around for the problem.

Look in the following code paste. It seems that taking a reference to 
the frame object crashes python in some scripts:

#
# trace_hell.py
#
# crashes with spe (stani's python editor) v0.7.3.a
#
# to see the crash add "import trace_hell; trace_hell.unleash_hell()" as
# the first line in spe.py
#
# 1. The statement that triggers the crash is "g_frame = frame"
#

import sys

g_frame = None

def tracer(frame, event, arg):
 global g_frame
 g_frame = frame
 return None

def unleash_hell():
 sys.settrace(tracer)
