tempfile behavior

Hi all,
I would like to use tempfile module to generate files having unique
names excepting that I don't want them to be removed after closing.
Does it is possible?

Looks like tempfile.mkstem p() will do what you want.

'''Unlike TemporaryFile() , the user of mkstemp() is responsible for
deleting the temporary file when done with it.'''

Thank you, it seems good.
Just another question:
>>fd, filename = tempfile.mkstem p()
type(fd)
<type 'int'>

I would expect a file descriptor, not and integer.
How do I have to use it?

File descriptors are integers. It's a low level C thing. Either use the
low level functions in `os` or open the file with the `filename`.

In particular, os.fdopen(fd) will give you a
file object.

Hi all! I am using Python 2.3.1 on Win32 (NT, 2000). Whenever a file imports the standard tempfile module, Python 2.3.1 issues the following warning: C:\Python23\lib\fcntl.py:7: DeprecationWarning: the FCNTL module is Deprecated; please use fcntl DeprecationWarning).

Hi! Is there a need for the "@" in the filenames created with tempfile.mktemp()? I think it would be better to use only characters which are "shell save". At least with bash you need to quote the "@". Copy&past of the filename does not work.

I've been working on a curses-based application in Python. My application effectively has a series of screens (or windows). When one screen closes, the previous screen should be exactly redrawin in its original state (i.e., before the sub-screen was created). As far as I can tell, the putwin() and getwin() functions can easily solve this problem. So I can do something like this: # draw/write some stuff on stdscr......

Tonight I discovered something odd in the __doc__ for tempfile as shipped with Python 2.4.4 and 2.5: it says: This module also provides some data items to the user: TMP_MAX - maximum number of names that will be tried before giving up. template - the default prefix for all temporary names. You may change this to control the default prefix.

Hi there. I'm trying to generate a brand new file with a unique name by using tempfile.mkstemp(). In conjunction I used os.fdopen() to get a wrapper around file properties (write & read methods, and so on...) but 'name' attribute does not contain the correct file name. Why? <fdopen> Moreover, I'd like to know if I'm doing fine. Does this approach avoid

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
