Python:无法识别next() [英] Python: next() is not recognized

问题描述

当我在python中执行next(ByteIter, '')<<8时，出现名称错误提示

When I do next(ByteIter, '')<<8 in python, I got a name error saying

未定义全局名称'next'"

"global name 'next' is not defined"

我猜测由于python版本无法识别此功能?我的版本是2.5.

I'm guessing this function is not recognized because of python version? My version is 2.5.

推荐答案

来自文档

next(iterator [，默认])

next(iterator[, default])

Retrieve the next item from the iterator by calling its next() method. 
If default is given, it is returned if the iterator is
exhausted, otherwise StopIteration is raised.

New in version 2.6.

是的，它确实需要2.6版.

So yes, it does require version 2.6.
