"In the following examples, input and output are distinguished by the "
"presence or absence of prompts (:term:`>>>` and :term:`...`): to repeat the "
"example, you must type everything after the prompt, when the prompt appears;"
" lines that do not begin with a prompt are output from the interpreter. Note"
" that a secondary prompt on a line by itself in an example means you must "
"type a blank line; this is used to end a multi-line command."
"在下面的例子中，通过提示符 (:term:`>>>` 与 :term:`...`) "
"的出现与否来区分输入和输出：如果你想复现这些例子，当提示符出现后，你必须在提示符后键入例子中的每一个词；不以提示符开头的那些行是解释器的输出。注意例子中某行中出现第二个提示符意味着你必须键入一个空白行；这是用来结束多行命令的。"

"Many of the examples in this manual, even those entered at the interactive "
"prompt, include comments.  Comments in Python start with the hash character,"
" ``#``, and extend to the end of the physical line.  A comment may appear at"
" the start of a line or following whitespace or code, but not within a "
"string literal.  A hash character within a string literal is just a hash "
"character. Since comments are to clarify code and are not interpreted by "
"Python, they may be omitted when typing in examples."
"这个手册中的许多例子都包含注释，甚至交互性命令中也有。Python中的注释以井号 ``#`` "
"开头，并且一直延伸到该文本行结束为止。注释可以出现在一行的开头或者是空白和代码的后边，但是不能出现在字符串中间。字符串中的井号就是井号。因为注释是用来阐明代码的，不会被"
" Python 解释，所以在键入这些例子时，注释是可以被忽略的。"

"One way to remember how slices work is to think of the indices as pointing "
"*between* characters, with the left edge of the first character numbered 0. "
"Then the right edge of the last character of a string of *n* characters has "
"index *n*, for example::"
"您也可以这么理解切片：将索引视作指向字符 *之间* ，第一个字符的左侧标为0，最后一个字符的右侧标为 *n* ，其中 *n* 是字符串长度。例如::"
#: /home/runner/work/docspush-transifex/docspush-transifex/cpython/Doc/tutorial/introduction.rst:301
"The first row of numbers gives the position of the indices 0...6 in the "
"string; the second row gives the corresponding negative indices. The slice "
"from *i* to *j* consists of all characters between the edges labeled *i* and"
" *j*, respectively."
"第一行数标注了字符串 0...6 的索引的位置，第二行标注了对应的负的索引。那么从 *i* 到 *j* 的切片就包括了标有 *i* 和 *j* "
"的位置之间的所有字符。"
#: /home/runner/work/docspush-transifex/docspush-transifex/cpython/Doc/tutorial/introduction.rst:306
"For non-negative indices, the length of a slice is the difference of the "
"indices, if both are within bounds.  For example, the length of "
"``word[1:3]`` is 2."
msgstr "对于使用非负索引的切片，如果索引不越界，那么得到的切片长度就是起止索引之差。例如， ``word[1:3]`` 的长度为2。"

"fact any sequence; anything with a non-zero length is true, empty sequences "
"are false.  The test used in the example is a simple comparison.  The "
"standard comparison operators are written the same as in C: ``<`` (less "
"than), ``>`` (greater than), ``==`` (equal to), ``<=`` (less than or equal "
"to), ``>=`` (greater than or equal to) and ``!=`` (not equal to)."
":keyword:`while` 循环只要它的条件（这里指： ``a < 10``）保持为真就会一直执行。Python 和 C "

" C 语言里是一样： ``<`` （小于）、 ``>`` （大于）、 ``==`` （等于）、 ``<=`` （小于或等于)、 ``>=`` "
"（大于或等于）以及 ``!=`` （不等于）。"

"The *body* of the loop is *indented*: indentation is Python's way of "
"grouping statements.  At the interactive prompt, you have to type a tab or "
"space(s) for each indented line.  In practice you will prepare more "
"complicated input for Python with a text editor; all decent text editors "
"have an auto-indent facility.  When a compound statement is entered "
"interactively, it must be followed by a blank line to indicate completion "
"(since the parser cannot guess when you have typed the last line).  Note "
"that each line within a basic block must be indented by the same amount."
"*循环体* 是 *缩进的* ：缩进是 Python 组织语句的方式。在交互式命令行里，你得给每个缩进的行敲下 Tab "
"键或者（多个）空格键。实际上用文本编辑器的话，你要准备更复杂的输入方式；所有像样的文本编辑器都有自动缩进的设置。交互式命令行里，当一个组合的语句输入时,"
" 需要在最后敲一个空白行表示完成（因为语法分析器猜不出来你什么时候打的是最后一行）。注意，在同一块语句中的每一行，都要缩进相同的长度。"

"The :func:`print` function writes the value of the argument(s) it is given. "
"It differs from just writing the expression you want to write (as we did "
"earlier in the calculator examples) in the way it handles multiple "
"arguments, floating point quantities, and strings.  Strings are printed "
"without quotes, and a space is inserted between items, so you can format "
"things nicely, like this::"
":func:`print` 函数将所有传进来的参数值打印出来. 它和直接输入你要显示的表达式(比如我们之前在计算器的例子里做的)不一样， print()"
" 能处理多个参数，包括浮点数，字符串。 字符串会打印不带引号的内容, 并且在参数项之间会插入一个空格, 这样你就可以很好的把东西格式化, 像这样::"

"Since ``**`` has higher precedence than ``-``, ``-3**2`` will be interpreted"
" as ``-(3**2)`` and thus result in ``-9``.  To avoid this and get ``9``, you"
" can use ``(-3)**2``."
"因为 ``**`` 比 ``-`` 有更高的优先级, 所以 ``-3**2`` 会被解释成 ``-(3**2)`` ，因此结果是 ``-9``.  "
"为了避免这个并且得到结果 ``9``, 你可以用这个式子 ``(-3)**2``."

"Unlike other languages, special characters such as ``\\n`` have the same "
"meaning with both single (``'...'``) and double (``\"...\"``) quotes. The "
"only difference between the two is that within single quotes you don't need "
"to escape ``\"`` (but you have to escape ``\\'``) and vice versa."
"和其他语言不一样的是, 特殊字符比如说 ``\\n`` 在单引号 (``'...'``) 和双引号 (``\"...\"``) 里有一样的意义. "
"这两种引号唯一的区别是，你不需要在单引号里转义双引号 ``\"`` (但是你必须把单引号转义成 ``\\'``) ， 反之亦然."
