Not easily. Attributes are stored in a dict; dicts don't preserve

Yes, the OS caches file and directory data so the second open is faster.

sorry this is not true:
There is a think left, i can't jus compare this:
if type(somethingA) == type(somthingB):
I transform type() to a string and then compare them.. (like in the code
below)

I don't know of any sort of official list of supported platforms.

Hi all,

in this case, my question is how do i replace "% (some,some,some)" with

I would check the docs on the www.python.org website.

multiple values, a common trick is to pass vars() or locals() as
the dict, giving the format access to all defined variables:
In [27]: a=1
In [28]: b=2
In [29]: print '%(a)s %(b)s' % vars()
1 2
If you literally need to repeat as in your example, you could do this:
In [26]: print &#

Another approach is to use dictionaries for string
replacement.
>>> subst = {'some': 'thing'}
>>> print "%(some)s%(some)s%(some)s" % subst

You appear to be referring to list comprehension. Here is a link to list
comprehension is the python docs
well it's true, using list it's scalable too. But It's doesn't looks
friendly to the user to write the document. Syntacticly looks nice to keep
some of the original structure of the html ( I mind, put the thags inside
the document, and so on ).
I'll making some test this days to see what i get,
Hi all,
This is a syntax that I've seen on occasion in other people's code:
theme = (VALID_THEMES[0], theme) [ theme in VALID_THEMES ]
I have no idea how this works, or how to go about looking it up. Can
someone enlighten me as to what's happening here?
Many thanks,

If you look closely at the end of the string there is an extra space.

No extra space.
