This module provides generic, low- and high-level interfaces for
creating temporary files and directories. All of the interfaces
provided by this module can be used without fear of race conditions
except for 'mktemp'. 'mktemp' is subject to race conditions and
should not be used; it is provided for backward compatibility only.
The default path names are returned as str. If you supply bytes as
input, all return values will be in bytes. Ex:
>>> tempfile.mkstemp()
(4, '/tmp/tmptpu9nin8')
>>> tempfile.mkdtemp(suffix=b'')
b'/tmp/tmppbi8f0hy'
This module also provides some data items to the user:
TMP_MAX - maximum number of names that will be tried before
giving up.
tempdir - If this is set to a string before the first use of
any routine from this module, it will be considered as
another candidate location to store temporary files.

This routine should be called exactly once.
We determine whether or not a candidate temp dir is usable by
trying to create and write to a file in that directory. If this
is successful, the test file is deleted. To prevent denial of
service, the name of the test file must be randomized.d s blatrQ z)No usable temporary directory found in %s)r0 r_ r r[ rV abspathrangenextrD open_bin_openflagswritecloseunlinkFileExistsErrorPermissionErrorrT isdiraccessW_OKr FileNotFoundError_errnoENOENT)namerr\ r, seqrT filenamefds r _get_default_tempdirrw s

file. The return value is a pair (fd, name) where fd is the
file descriptor returned by os.open, and name is the filename.
If 'suffix' is not None, the file name will end with that suffix,
otherwise there will be no suffix.
If 'prefix' is not None, the file name will begin with that prefix,
otherwise a default prefix is used.
If 'dir' is not None, the file will be created in that directory,
otherwise a default directory is used.
If 'text' is specified and true, the file is opened in text
mode. Else (the default) the file is opened in binary mode.
If any of 'suffix', 'prefix' and 'dir' are not None, they must be the
same type. If they are bytes, the returned name will be bytes; str
otherwise.
The file is readable and writable only by the creating user ID.
If the operating system uses permission bits to indicate whether a
file is executable, the file is executable by no one. The file
descriptor is not inherited by children of this process.
Caller is responsible for deleting the file when done with it.
