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.

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. On
some operating systems, this makes no difference.
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.

refer to a file that did not exist at some point, but by the time
you get around to creating it, someone else may have beaten you to

Y nX dS )a Create and return a temporary file.
Arguments:
'prefix', 'suffix', 'dir' -- as for mkstemp.
'mode' -- the mode argument to io.open (default "w+b").
'buffering' -- the buffer size argument to io.open (default -1).
'encoding' -- the encoding argument to io.open (default None)
'newline' -- the newline argument to io.open (default None)
'delete' -- whether the file is deleted on close (default True).
The file is created as mkstemp() would do it.
Returns an object with a file-like interface; the name of the file
is accessible as its 'name' attribute. The file will be automatically
deleted when it is closed unless the 'delete' argument is set to False.
