We also can use a set of functions that's built into Python strings called ljust and rjust. Ljust will left justify the string, padding the right side with whatever character you want.

我们也可以用一系列的函数——ljust和rjust，来形成Python字符串。ljust函数可以左对齐字符串，在右边你想填多少字符就可以填多少。

Note that we give getmro itself as an argument to facilitate recursion in older Python versions that did not support lexically nested scopes.

注意我们将函数getmtro作为递归参数传入，这样可以处理python的旧版本中不支持嵌套语法作用域。

Earlier versions of Python used lexicographic comparison of the sorted lists, but this was very expensive for the common case of comparing

之前的Python使用排序后的列表进行字典序的比较，但这在进行相等比较时代价非常高。

Earlier versions of Python used lexicographic comparison of the sorted lists, but this was very expensive for the common case of comparing for equality.

之前的Python使用排序后的列表进行字典序的比较，但这在进行相等比较时代价非常高。

By popular demand, a few features commonly found in functional programming languages and Lisp have been added to Python.

出于适当的需要，有几种通常在功能性语言和 Lisp 中出现的功能加入到了 Python 。

Many past Lisp programmers have found Python appealing for this reason.

很多曾经的Lisp程序员发现Python在这方面是很有吸引力的。

We mentioned above during our introduction to Python's for loop that it is an iterative looping mechanism.

我们在前面介绍Python的for循环的时候提到它是一种迭代的循环机制。

Python's while is the first looping statement we will look at in this chapter.

Python 的 while 是本章我们遇到的第一个循环语句。

In this mode, Python acts as an embedded control language (what some call a "macro" language).

在这一模式下，Python是一种内嵌式的控制语言。

It is not a full functioned object-relational mapper for python - it deals best with simple data types structured in ways that can be easily represented in a relational database.

它并不是一个关系对象函数在Python的完整映射-它和关系数据库表现的简单数据类型结构协作的非常好。

The work of this paper is as follows: 1. Looking back the progressing history of the linear motor, introducing the features of the elevator driven by linear induction motor, radicating the topic of this paper "the digital frequency variable control of the elevator bi-side direct driven by linear induction motor". The research of this paper covers the conventional VVVF control, space vector based VVVF control, vector control and DTC.

本文主要开展了以下几个方面的工作： 1 回顾了直线电机发展历史，电机的驱动技术演变，特别是针对直线电机的驱动，简要介绍了直线感应电机驱动电梯的优点和不同结构类型，对传统的v／f控制，基于空间矢量法的v／f控制，矢量控制，和基于电压空间矢量的直接转矩控制进行了比较，确立了本课题的研究主题：直线感应电机双边直推式驱动电梯的全数字变频控制。

The article combines with the treatment of a superficial civil air defense work to introduce how the grouting method to improve the performance of the backfill soil.

文章从治理漂浮人防工事的角度提出了注浆技术在改善回填土性质方面的应用，并详细阐述了注浆技术的施工流程。
