"The Python interpreter is usually installed as "

":file:`/usr/local/bin/python3.9` on those machines where it is available; "

"putting :file:`/usr/local/bin` in your Unix shell's search path makes it "

"possible to start it by typing the command:"

msgid ""

"to the shell. [#]_ Since the choice of the directory where the interpreter "

"lives is an installation option, other places are possible; check with your "

"local Python guru or system administrator. (E.g., :file:`/usr/local/python`"

" is a popular alternative location.)"

msgstr ""

"这样，就可以在 shell 中运行 Python 了 [#]_ 。因为可以选择安装目录，解释器也有可能安装在别的位置；如果还不明白，就去问问身边的 "

"Python 大神或系统管理员。（例如，常见备选路径还有 :file:`/usr/local/python`。）"

"Typing an end-of-file character (:kbd:`Control-D` on Unix, :kbd:`Control-Z` "

"the following command: ``quit()``."

msgstr ""

"在主提示符中，输入文件结束符（Unix 里是 :kbd:`Control-D`，Windows 里是 "

"The interpreter's line-editing features include interactive editing, history"

" substitution and code completion on systems that support the `GNU Readline "

"<https://tiswww.case.edu/php/chet/readline/rltop.html>`_ library. Perhaps "

"the quickest check to see whether command line editing is supported is "

"typing :kbd:`Control-P` to the first Python prompt you get. If it beeps, "

"you have command line editing; see Appendix :ref:`tut-interacting` for an "

"introduction to the keys. If nothing appears to happen, or if ``^P`` is "

"echoed, command line editing isn't available; you'll only be able to use "

"backspace to remove characters from the current line."

msgstr ""

"在支持 `GNU Readline <https://tiswww.case.edu/php/chet/readline/rltop.html>`_ "

"库的系统中，解释器的行编辑功能包括交互式编辑、历史替换、代码补全等。检测是否支持命令行编辑最快速的方式是，在首次出现 Python 提示符时，输入 "

":kbd:`Control-P`。听到“哔”提示音，说明支持行编辑；请参阅附录 :ref:`tut-"

"interacting`，了解功能键。如果没有反应，或回显了 ``^P``，则说明不支持行编辑；只能用退格键删除当前行的字符。"

"The interpreter operates somewhat like the Unix shell: when called with "

"standard input connected to a tty device, it reads and executes commands "

"interactively; when called with a file name argument or with a file as "

"standard input, it reads and executes a *script* from that file."

msgstr ""

"解释器的操作方式类似 Unix Shell：用与 tty "

"设备关联的标准输入调用时，可以交互式地读取和执行命令；以文件名参数，或标准输入文件调用时，则读取并执行文件中的 *脚本*。"

#: ../../tutorial/interpreter.rst:51

msgid ""

"A second way of starting the interpreter is ``python -c command [arg] ...``,"

" which executes the statement(s) in *command*, analogous to the shell's "

":option:`-c` option. Since Python statements often contain spaces or other "

"characters that are special to the shell, it is usually advised to quote "

"*command* in its entirety with single quotes."

"Some Python modules are also useful as scripts. These can be invoked using "

"``python -m module [arg] ...``, which executes the source file for *module* "

"as if you had spelled out its full name on the command line."

msgstr ""

"Python 模块也可以当作脚本使用。输入：``python -m module [arg] ...``，会执行 *module* "

"的源文件，这跟在命令行把路径写全了一样。"

#: ../../tutorial/interpreter.rst:61

msgid ""

"When a script file is used, it is sometimes useful to be able to run the "

"script and enter interactive mode afterwards. This can be done by passing "

":option:`-i` before the script."

msgstr "在交互模式下运行脚本文件，只要在脚本名称参数前，加上选项 :option:`-i` 就可以了。"

"When known to the interpreter, the script name and additional arguments "

"thereafter are turned into a list of strings and assigned to the ``argv`` "

"variable in the ``sys`` module. You can access this list by executing "

"``import sys``. The length of the list is at least one; when no script and "

"no arguments are given, ``sys.argv[0]`` is an empty string. When the script"

" name is given as ``'-'`` (meaning standard input), ``sys.argv[0]`` is set "

"to ``'-'``. When :option:`-c` *command* is used, ``sys.argv[0]`` is set to "

"``'-c'``. When :option:`-m` *module* is used, ``sys.argv[0]`` is set to "

"the full name of the located module. Options found after :option:`-c` "

"*command* or :option:`-m` *module* are not consumed by the Python "

"interpreter's option processing but left in ``sys.argv`` for the command or"

" module to handle."

msgstr ""

"解释器读取命令行参数，把脚本名与其他参数转化为字符串列表存到 ``sys`` 模块的 ``argv`` 变量里。执行 ``import "

"sys``，可以导入这个模块，并访问该列表。该列表最少有一个元素；未给定输入参数时，``sys.argv[0]`` 是空字符串。给定脚本名是 "

"``'-'`` （标准输入）时，``sys.argv[0]`` 是 ``'-'``。使用 :option:`-c` *command* "

"时，``sys.argv[0]`` 是 ``'-c'``。如果使用选项 :option:`-m` *module*，``sys.argv[0]`` "

"就是包含目录的模块全名。解释器不处理 :option:`-c` *command* 或 :option:`-m` *module* "

"*interactive mode*. In this mode it prompts for the next command with the "

"*primary prompt*, usually three greater-than signs (``>>>``); for "

"dots (``...``). The interpreter prints a welcome message stating its version"

" number and a copyright notice before printing the first prompt:"

"By default, Python source files are treated as encoded in UTF-8. In that "

"encoding, characters of most languages in the world can be used "

"simultaneously in string literals, identifiers and comments --- although the"

" standard library only uses ASCII characters for identifiers, a convention "

"that any portable code should follow. To display all these characters "

"properly, your editor must recognize that the file is UTF-8, and it must use"

" a font that supports all the characters in the file."

msgstr ""

"默认情况下，Python 源码文件的编码是 UTF-8。这种编码支持世界上大多数语言的字符，可以用于字符串字面值、变量、函数名及注释 —— "

"尽管标准库只用常规的 ASCII 字符作为变量名或函数名，可移植代码都应遵守此约定。要正确显示这些字符，编辑器必须能识别 UTF-8 "

"编码，而且必须使用支持文件中所有字符的字体。"

"To declare an encoding other than the default one, a special comment line "

"should be added as the *first* line of the file. The syntax is as follows::"
