file是python中的关键字吗?

Is file a keyword in python?

我已经看到一些使用关键字file的代码很好，而其他代码则建议不要使用它，而我的编辑器则将其作为关键字进行颜色编码.

I've seen some code using the keyword file just fine, while others have suggested not to use it and my editor is color coding it as a keyword.

推荐答案

否，file是内置的，而不是关键字:

No, file is a builtin, not a keyword:

>>> import keyword
>>> keyword.iskeyword('file')
False
>>> import __builtin__
>>> hasattr(__builtin__, 'file')
True

它可以看作是open()的别名，但已从Python 3中删除，因为它是新的 io框架替换了它.从技术上讲，它是open()函数返回的对象的类型.

It can be seen as an alias for open(), but it has been removed from Python 3, as the new io framework replaced it. Technically, it is the type of object returned by the open() function.
