Function mkstemp

Lib/tempfile.py:318–354

User-callable function to create and return a unique temporary 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 suf

    file is executable, the file is executable by no one. The file

    Caller is responsible for deleting the file when done with it.
