easy way to return a list of absolute file or directory path within a directory

[iMath]

Any easier solutions on returning a list of absolute file or directory path 
within a directory? Mine is  

list(map(lambda entry: os.path.join(directory,entry),os.listdir(directory)))

Use a list comprehension:


[os.path.join(directory,entry) for entry in os.listdir(directory)]

Fwd: Fwd: Python freeze fails with warning: the use of `tempnam' is dangerous, better use `mkstemp'

[Alexander N. Moibenko]

Hello,
when I build a binary with python 2.6 it builds without any problem.
When I build with python 2.7 the build fails after warnings like:
/opt/python/Python-2.7.12/Modules/posixmodule.o: In function 
`posix_tempnam':
/opt/python/Python-2.7.12/./Modules/posixmodule.c:7578: warning: the use 
of `tempnam' is dangerous, better use `mkstemp'

collect2: ld returned 1 exit status

How this can be fixed?
Thanks,

How to split value where is comma ?

Here is my view.py

When i run this command it gives output which you can see...

Is your question "Given a string that may contain some commas, how
do I insert a newline after each comma"?   (Note that that is *not*
what you show, but from what you show I can't tell what you want.)

The clearest answer is already there in the warning message. Replace
your use of ‘tempnam’ with ‘mkstemp’.

If you don't know what that means because you didn't write the code,
then this is for whoever is maintaining that code. Read it, learn what
it does, find (or write) its unit tests to make sue you don't break
anything; then, change that usage as suggested.

Your add() function returns None (because it has no return statements).
Your failing statement is assigning that None to a["007-12"].

There are a number of helpful structures in Python to do this work for
you.  collections.Counter will probably be helpful:

>>> from collections import Counter
>>> a = Counter()
>>> a["007-12"] += 22
>>> a
Counter({'007-12': 22})
>>> a["007-12"] += 22
>>> a
Counter({'007-12': 44})

On Thursday, August 18, 2016 at 2:36:31 PM UTC+12, I wrote:
> Solution: set up a table of rules ...

Here  is another 
example. The problem is to list all external file dependencies of a Blender 
document, to ensure that they exist etc. Currently, as far as I know, these 
external files might be fonts, images, libraries (additional Blender documents 
containing linked assets) and sounds. The processing for all of these is very 
similar. But within some categories, there are special cases for items which 
need to be ignored. So my loop starts like this:

for \
category, match, mismatch, extra \
in \
(
("fonts", {}, (("filepath" , ""),), ()),
("images", {"type" : "IMAGE"}, (), ("filepath_raw",)),
("libraries", {}, (), ()),
("sounds", {}, (), ()),
) \
:
...

where “match” is a dictionary where each key is an attribute name, and the 
value is the corresponding value that the attribute must have, while “mismatch” 
is a tuple of (key, value) 2-tuples, where each “key” is an attribute name, and 
“value” is a value that attribute must *not* have. The table is designed so 
that I can easily add new categories, and new criteria for each category, as I 
discover them in future.

So, within the above category loop, I loop over all items in the Blender 
document within that category that match the specified criteria:

for item in getattr(bpy.data, category) :
if (
item.packed_file == None
and
not any(getattr(item, k) == v for k, v in mismatch)
and
all(getattr(item, k) == match[k] for k in match)
) :

That additional “item.packed_file == None” check indicates that the object is 
not stored in the .blend file, but resides in an external file. That, at least, 
is a common characteristic of all object categories (so far...).

My usual way of debugging C code is to stick printf statements close to where I 
think the problem areas might be. Write to stderr, not stdout, so you can

I doubt that the (compiler) warning is responsible for the (linker) failure.

When I am faced with problems like this (usually during extension building;
I have never encountered a problem during a Python built), I try
to find out what (OS level) commands are executed by the build machinery
and then issue them manually on the command line: the build machinery
often hides error details revealed by executing the commands
directly on the command line.


What I can imagine is that your (OS level installed) C libraries (i.e. "libc"
and friends) no longer contain a "tempnam", letting the linker fail.
Thus, maybe, the compiler still warns about "tempnam" but the linker
already considers it as an error.
