namedtuple._source在python 3.7中不起作用 [英] namedtuple._source not working in python 3.7

问题描述

我已经尝试过使用此代码

I've tried with this code

from collections import namedtuple
t = namedtuple('t', 'a b c')
i = t(1,2,3)
print(i._source, t._source)

但是当我运行它时，它说没有属性 _source (对于 t ，因此对于 i ).自3.6以来已被淘汰吗?

But when I run it it says that there is no attribute _source (for t and therefore also for i). Has it been eliminated since 3.6?

推荐答案

是的，如

Yes, as stated here, the attribute _source has been removed from namedtuples in Python 3.7.

在3.7版中已更改:删除 verbose 参数和 _source 属性.
