将__filename__预定义属性添加到2.5？ [英] Adding a __filename__ predefined attribute to 2.5?

问题描述

是否可以将新的__filename__预定义属性包含在

2.5中，以便__file__包含模块的完整路径，并且

__filename__只包含名称模块？

例如，在脚本用法（）部分中包含对

文件名的非静态引用是很有用的提取

文件名或执行模块导入只是为了解析它很麻烦。

Is it an idea to include a new __filename__ predefined attribute to
2.5, so that __file__ contains the entire path to the module, and
__filename__ only the name of the module?

For instance it''s useful to include a not-static reference to the
filename in a scripts usage() section and it''s cumbersome to extract
the filename or to do module imports just to parse it.

No. 不是通常一个好主意，把它加（其中大部分时间它从你的程序

消除复杂性是没有必要的）底层

系统。这里有一个关于如何在没有__file__的情况下完成任务的线索：

No. It''s not usually a good idea to remove complexity from your program
by adding it (where most of the time it''s not needed) to the underlying
system. Here''s a clue as to how you might do without __file__ altogether:

sholden@bigboy ~/Projects/Python

cat test78.py

import sys

print sys.argv

sholden @ bigboy~ / Projects / Python

cat test78.py
import sys
print sys.argv

sholden@bigboy ~/Projects/Python

python test78.py我们可以说与它一起生活吗？

[''test78.py''，''可以''，''我们'' ，''''，''直播''，''带''，''它？''']
