查询词典 Denes

And also denes the possible values for objects of that type.

对象的类型也是不可变的，它用于检测对象支持的操作例如，&&有长度吗？

It is executed in the same namespace where interactive commands are executed, so that objects that it denes or imports can be used without qualication in the interactive session.

它与解释器执行的命令处在同一个命名空间，所以由它定义或引用的一切可以在解释器中不受限制的使用。

It also denes the basic theory of multidimensional digital signal processing, particularly with respect to how linear and nonlinear ltering, transform computation, and sampling are generalized from the one-dimensional case.

它还denes的基本理论的多维数字信号处理，特别是关于如何线性和非线性ltering ，变换计算，和取样是广义的一维情况。

If a class denes neither len nor nonzero, all its instances are considered true.

当此方法未定义时，义 len ，没有定义 nonzero，那么它就被看作为真。

If a class denes mutable objects and implements a cmp or eq method, it should not implement hash, since the dictionary implementation requires that a key's hash value is immutable (if the object's hash value changes, it will be in the wrong hash bucket).

如果类定义的是可变对象并且实现了 cmp或 eq方法，它就不应该实现 hash，因为字典实现一个散列表的键值是不可变的(如果对象的散列值改变了，它会放在错误的散列表位置中)。

It is executed in the same namespace where interactive commands are executed, so that objects that it denes or imports can be used without qualication in the interactive session.

这个文件在交互会话期是只读的，当Python 从脚本中解读文件或以终端'/dev/tty'做为外部命令源时则不会如此尽管它们的行为很像是处在交互会话期。

If a class cmp method it should not dene a hash operation either; if it denes does not dene a cmp or eq but not hash, its instances will not be usable as dictionary keys.

如果类没有定义 cmp方法，它也不应该定义 hash操作；如果类定义了 cmp或 eq但没有 hash，它的实例就不能作为散列表的键使用。

The import statement uses the following convention: if a package's '__init__.py' code denes a list named __all__, it is taken to be the list of module names that should be imported when from package import * is encountered.

包Packages 55 对于包的作者来说唯一的解决方案就是给提供一个明确的包索引。import 语句按如下条件进行转换：执行from package import *时，如果包中的'__init__。py'代码定义了一个名为__all__ 的链表，就会按照链表中给出的模块名进行导入。

Special attributes: func doc or doc is the function's documentation string, or None if unavailable; func name or name is the function's name; module is the name of the module the function was dened in, or None if unavailable; func defaults is a tuple containing default argument values for those arguments that have defaults, or None if no arguments have a default value; func code is the code object representing the compiled function body; func globals is the dictionary that holds the function's global variables — it denes the global namespace of the module in which the function was dened; func dict or dict contains the namespace supporting arbitrary function attributes; func closure is None or a tuple of cells that contain bindings for the function's free variables.

func defaults是一个包括有参数中设有默认值的元组；func name 或 name 是函数名。func code是一个编译后的代码对象；func globals是一个引用，指向保存了函数的全局变量的字典—-如果你在函数所在模块中定义了全局变量的话。func dict或 dict 包括了支持任意函数属性的名字空间；func closure 要么是None，要么是包括有函数自由变量捆绑的单元的元组。

Equation (1a) denes the three cost-revenue objective cri- teria to minimize initial capital cost, minimize annual op- erating cost, and maximize annual income revenue (i.e., minimize 1/annual income revenue) for the oce build- ing.

方程（1A）条定义了三个成本，收入目标光绪特里亚减少初始资金成本，减少每年的运算 erating成本，并最大限度地年收入收入（即，收入减少1/annual收入）为办公构建荷兰国际集团。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
