I'm a win7-user.

I accidentally read about redirections (like `command1 < infile > outfile`) in \*nix systems, and then I discovered that [something similar can be done in Windows (link)](http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/redirection.mspx?mfr=true). And python is also can do something like this with pipes(?) or stdin/stdout(?).

I do not understand how this happens in Windows, so I have a question.

I use some kind of proprietary windows-program (.exe). This program is able to append data to a file.
For simplicity, let's assume that it is the equivalent of something like

```
while True:
    f = open('textfile.txt','a')
    f.write(repr(ctime()) + '\n')
    f.close()
    sleep(100)

```

**The question:**
Can I use this file (textfile.txt) as stdin?
I mean that the script (while it runs) should always (not once) handle all new data, ie

In the "never-ending cycle":

* The program (.exe) writes something.
* Python script captures the data and processes.

Could you please write how to do this in python, or maybe in win cmd/.bat or somehow else.

**This is insanely cool thing. I want to learn how to do it! :D**
