It gets created:
In [24]: import tempfile
In [25]: t = tempfile.NamedTemporaryFile()
In [26]: t.name
Out[26]: '/tmp/tmp9bmhap'
In [27]: ls -l /tmp/tmp*
-rw------- 1 jmjones jmjones 0 Nov 22 11:15 /tmp/tmp9bmhap
In [28]: t.write("123")
In [29]: t.flush()
In [30]: ls -l /tmp/tmp*
-rw------- 1 jmjones jmjones 3 Nov 22 11:15 /tmp/tmp9bmhap
In [31]: t.close()
In [32]: ls -l /tmp/tmp*
ls: /tmp/tmp*: No such file or directory
From the docstring, it gets automatically deleted on close:
def NamedTemporaryFile(mode='w+b', bufsize=-1, suffix="",
prefix=template, dir=None):
"""Create and return a temporary file.
Arguments:
'prefix', 'suffix', 'dir' -- as for mkstemp.
'mode' -- the mode argument to os.fdopen (default "w+b").
'bufsize' -- the buffer size argument to os.fdopen (default -1).
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 file.name. The file will be automatically deleted
when it is closed.
