The tempfile
module in Example 2-6 allows you to quickly come up with unique names to use for
temporary files.
Example 2-6. Using the tempfile Module to Create Filenames for Temporary Files
File: tempfile-example-1.py import tempfile import os tempfile = tempfile.mktemp() print "tempfile", "=>", tempfile file = open(tempfile, "w+b") file.write("*" * 1000) file.seek(0) print len(file.read()), "bytes" file.close() try: # must remove file when done os.remove(tempfile) except OSError: passtempfile => C:TEMP~160-1
1000 bytes
The TemporaryFile
function picks a suitable name
and opens the file, as shown in Example 2-7. It also makes sure that the file is removed when
it’s closed. (On Unix, you can remove an open file and have it
disappear when the file is closed. On other platforms, this is done
via a special wrapper class.)
