python中如何创建带有文件名的临时文件？

def NamedTemporaryFile(mode='w+b', buffering=-1, encoding=None,

                       newline=None, suffix=None, prefix=None,

                       dir=None, delete=True, *, errors=None)

import os

import tempfile

temp = tempfile.NamedTemporaryFile()

try:

    print 'temp:', temp

    print 'temp.name:', temp.name

finally:

    # Automatically cleans up the file

    temp.close()

print 'Exists after close:', os.path.exists(temp.name)
