-You want a script you’ve written to be able to accept input using whatever mechanism
-is easiest for the user. This should include piping output from a command to the script,
-redirecting a file into the script, or just passing a filename, or list of filenames, to the
-script on the command line.
+你希望你的脚本接受任何用户认为最简单的输入方式。包括将命令行的输出通过管道传递给该脚本、
+重定向文件到该脚本，或在命令行中传递一个文件名或文件名列表给该脚本。

 解决方案
 ----------
-Python’s built-in fileinput module makes this very simple and concise. If you have a
-script that looks like this:
-#!/usr/bin/env python3
-import fileinput
+Python内置的 ``fileinput`` 模块让这个变得简单。如果你有一个下面这样的脚本：
 
-with fileinput.input() as f_input:
-    for line in f_input:
-        print(line, end='')
+.. code-block:: python
 
-Then you can already accept input to the script in all of the previously mentioned ways.
-If you save this script as filein.py and make it executable, you can do all of the following
-and get the expected output:
+    #!/usr/bin/env python3
+    import fileinput
 
-$ ls | ./filein.py          # Prints a directory listing to stdout.
-$ ./filein.py /etc/passwd   # Reads /etc/passwd to stdout.
-$ ./filein.py < /etc/passwd # Reads /etc/passwd to stdout.
+    with fileinput.input() as f_input:
+        for line in f_input:
+            print(line, end='')
+
+那么你就能以前面提到的所有方式来为此脚本提供输入。假设你将此脚本保存为 ``filein.py`` 并将其变为可执行文件，
+那么你可以像下面这样调用它，得到期望的输出：
+
+.. code-block:: python
+
+    $ ls | ./filein.py          # Prints a directory listing to stdout.
+    $ ./filein.py /etc/passwd   # Reads /etc/passwd to stdout.
+    $ ./filein.py < /etc/passwd # Reads /etc/passwd to stdout.

 讨论

-The  fileinput.input() function creates and returns an instance of the  FileInput
-class. In addition to containing a few handy helper methods, the instance can also be
-used as a context manager. So, to put all of this together, if we wrote a script that expected
-to be printing output from several files at once, we might have it include the filename
-and line number in the output, like this:
+``fileinput.input()`` 创建并返回一个 ``FileInput`` 类的实例。
+该实例除了拥有一些有用的帮助方法外，它还可被当做一个上下文管理器使用。
+因此，整合起来，如果我们要写一个打印多个文件输出的脚本，那么我们需要在输出中包含文件名和行号，如下所示：
 
->>> import fileinput
->>> with fileinput.input('/etc/passwd') as f:
->>>     for line in f:
-...         print(f.filename(), f.lineno(), line, end='')
-...
-/etc/passwd 1 ##
-/etc/passwd 2 # User Database
-/etc/passwd 3 #
+.. code-block:: python
 
-<other output omitted>
+    >>> import fileinput
+    >>> with fileinput.input('/etc/passwd') as f:
+    >>>     for line in f:
+    ...         print(f.filename(), f.lineno(), line, end='')
+    ...
+    /etc/passwd 1 ##
+    /etc/passwd 2 # User Database
+    /etc/passwd 3 #
 
-Using it as a context manager ensures that the file is closed when it’s no longer being
-used, and we leveraged a few handy FileInput helper methods here to get some extra
-information in the output.
+    <other output omitted>
+
+通过将它作为一个上下文管理器使用，可以确保它不再使用时文件能自动关闭，
+而且我们在之类还演示了 ``FileInput`` 的一些有用的帮助方法来获取输出中的一些其他信息。
