TemporaryFile
- TemporaryFile(mode='w+b', buffering=-1, encoding=None, newline=None, suffix=None, prefix=None, dir=None, *, errors=None)
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) 'errors' -- the errors argument to io.open (default None) The file is created as mkstemp() would do it. Returns an object with a file-like interface. The file has no name, and will cease to exist when it is closed.

1 Example
>>> import tempfile # create a temporary file and write some data to it >>> fp = tempfile.TemporaryFile() >>> fp.write(b'Hello world!') # read data from file >>> fp.seek(0) >>> fp.read() b'Hello world!' # close the file, it will be removed >>> fp.close() # create a temporary file using a context manager >>> with tempfile.TemporaryFile() as fp: ... fp.write(b'Hello world!') ... fp.seek(0) ... fp.read() b'Hello world!' >>> # file is now closed and removed # create a temporary file using a context manager # close the file, use the name to open the file again >>> with tempfile.NamedTemporaryFile(delete_on_close=False) as fp: ... fp.write(b'Hello world!') ... fp.close() ... # the file is closed, but not removed ... # open the file again by using its name ... with open(fp.name, mode='rb') as f: ... f.read() b'Hello world!' >>> # file is now removed # create a temporary directory using the context manager >>> with tempfile.TemporaryDirectory() as tmpdirname: ... print('created temporary directory', tmpdirname) >>> # directory and contents have been removed
