从python脚本调用编辑器（vim）

调用$ EDITOR很容易。我已经编写了这种代码来调用编辑器：

import sys, tempfile, osfrom subprocess import callEDITOR = os.environ.get('EDITOR','vim') #that easy!initial_message = "" # if you want to set up the file somehowwith tempfile.NamedTemporaryFile(suffix=".tmp") as tf:  tf.write(initial_message)  tf.flush()  call([EDITOR, tf.name])  # do the parsing with `tf` using regular File operations.  # for instance:  tf.seek(0)  edited_message = tf.read()

这里的好处是，库可以处理创建和删除临时文件。
