Output a python script to text file
提问by Bob
I'm using a script that someone else wrote in python. It's executed from the command line with 3 arguments.
我正在使用其他人用 python 编写的脚本。它是从带有 3 个参数的命令行执行的。
example: "python script.py 1111 2222 3333"
示例：“python script.py 1111 2222 3333”
It does it's thing and works perfectly. The results are NOT saved though, and I would really like to pipe the output to a text file. Can I simply use similar dos commands to accomplish this? ie "...333 > output.txt"
它做它的事情并且完美地工作。虽然结果没有保存，但我真的很想将输出通过管道传输到文本文件。我可以简单地使用类似的 dos 命令来完成这个吗？即“...333 > output.txt”
I don't really want to post the script here if possible since it's not really my work.
如果可能的话，我真的不想在这里发布脚本，因为这不是我的工作。

That seems to work fine for me in the DOS shell.
这在 DOS shell 中对我来说似乎很好用。

f = open('/path/to/file','w')
f.write(string, '\n') # ... etc.
Should be simple enough to add something like that to the script, just in case you'd rather not have to use the shell to pipe output each time.
应该足够简单，可以将类似的内容添加到脚本中，以防万一您不想每次都使用 shell 来管道输出。

Redirection works fine both in unix-y shells andin Windows' cmd.exe(which I suspect is what you're calling "the DOS window"... unless you're managing to run Python on Windows '95 or something!-).
重定向在 unix-y shell和Windows 中都可以正常工作cmd.exe（我怀疑这就是您所说的“DOS 窗口”……除非您设法在 Windows 95 或其他系统上运行 Python！-）。
$ python script.py 1111 2222 3333 >output.txt
where the $is notsomething you type, but rather stands for "whatever prompt your shell / command window is giving you". Just to be totally unambiguous, what you dotype at said prompt to get redirection is just:
其中$是不是东西，你打字，而是表示“任何提示你的shell /命令窗口是给你的。” 只是为了完全明确的，你什么都请在说提示符下，得到重定向就是：
python script.py 1111 2222 3333 >output.txt
just like what you type now (without redirection) is
就像你现在输入的（没有重定向）是
python script.py 1111 2222 3333
