方法/步骤 1 python 3的命名元组在collections模块内，如图。构造命名元组非常简单，使用namedtuple然后指定类型名和各个字段名。2 各个字段名除了可以写成一个字符串，空格隔开，也可以写成一个列表，如图。要读取字段值，使用'.'运算符。3 此外，命名元组还可以通过数字下标读取各个字段，也可以多赋值来展开...
是不是很有趣?Point就像一个定义过x和y属性的类一样,可以直接创建实例,而所有实例都可以用.x,.y的形式访问其属性,这可比直接定义类要省事多了:
Any tuple subclass whose indexable elements are also accessible using named attributes (for example, time.localtime() returns a tuple-like object where the year is accessible either with an index such as t[0] or with a named attribute like t.tm_year). A named tuple can be a built-in t...
for current_index, current_value in enumerate(self)) return self.fromValues(values) return setter For comparison, I've seen similar ideas at http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/500261 and http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/303439 but I don't like the...
可以发现param是由2个元素组成的tuple, 其中第一个元素是str类型的,表示参数的名字, 第二个元素是torch.nn.parameter.Parameter类型的,表示包含的参数信息 named_children() 方法 可以通过调用nn.Module的named_children()方法来查看这个nn.Module的直接子级的模块: import torch.nn.functional as F class Net(nn...
I'd like to request that the TC consider adoption of a new chapter in the typing spec that spells out type checking behaviors related to named tuples. Links to PR & Discussion The PR can be found here. The latest draft incorporates feedback from PR reviews and the discussion. The ...
