Practically all Python objects have a string presentation either evaluatable from repr( or '', or printable from str. The print statement automatically invokes the str function for an object. This gets even better. When you are defining your own objects, there are hooks for you to create string representations of your object such that repr and str (and '' and print) return an appropriate string as output. And if worse comes to worst and neither repr or str is able to display an object, the Pythonic default is at least to give you something of the format

事实上，所有的Python对象都有一个字符串表示形式（通过repr函数，''或者str函数来展现）。print语句自动为每个对象调用该对象的str方法，这种机制的一个额外的好处就是在你定义你自己的对象时，你可以利用这种机制定义repr(，str或者''或者print来为你的对象创建一种字符串表达形式，它可以在被调用时返回适当的字符串描述信息，这样即使在坏的不能再坏的情况下，repr或者str起码可以给你返回一个对象的信息，Pythonic方式的默认做法是起码给你返回想如下格式的信息

this paper introduces a lossless detected circuit system.firstly,system gathers slender infrared signal with transducer,then amplifies them with low noise.through voltage comparator circuit,transforming simulation objection signals to digital signals.finally,transforming transport landscape orientation and portrait to single chip processing.in design of pcb,the amplifying of quadruplet signal,filter,voltage comparator decree and and logic function are manufactured in one board.if the diameter of workpiece is long,it can add multiple the number of transducer of four,to wide its range of practice,disposing circuit only need one module.

摘 要：介绍了一种无损检测的电路系统。系统首先利用传感器采集到微弱的缺陷信号，再将缺陷信号进行低噪声放大，然后通过电压比较判决电路将模拟缺陷信号变换成数字信号，最终将横、纵两路的输出信号送至单片机处理。在pcb设计中，将四路信号的放大、滤波、电压判决以及与逻辑功能做在一块板上，若被检测工件的直径较大，可以将传感器的个数以四的倍数增加，处理电路只需增加一个模块。

Obtaining the qualitative factors,and achieve the conversion from qualitative to quantitative by the theory of quantification, and in combination with other quantitative factors. Then use SPSSto analyse its correlation and variance. In order to find the influence which the factor affect the water resources carrying capacity, eventually form the main factors for water resources carrying capacity of karst area.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
