  Thank you.
  findstr doesn't need quotes, so it works.

 Build the command line yourself -instead of using a list of arguments-. Popen 
 doesn't play with the quotes in that case:

 p1 = Popen(['netstat', '-an'], stdout = PIPE) # using list
 p2 = Popen('find 445', stdin = p1.stdout, stdout = PIPE) # using str
 print p2.communicate()[0]

Thanks very much.

Get rid of the extra quotes.  ie:

The quotes on the command line and on the os.system call are consumed

You must be a linux user:)

I guess, in windows, the quotes are consumed by the c runtime library.
Mayby the find in windows doesn't use the argc/argv but the windows
API GetCommandLine().

I wrote a c program to prove it.

#include windows.h
#include stdio.h

int main(int argc, char **argv) {
int i;

printf(%s\n, GetCommandLine());
for (i = 0; i  argc; ++i)
printf(%d: %s\n, i, argv[i]);

return 0;
}

The output is:
C:\test 1 2 3
test 1 2 3
0: test
1: 1
2: 2
3: 3

C:\

Notice that, GetCommandLine() does not consume the quotes, but the
(char **argv) does.

While there certainly are valid usecases for piping with subprocess in
Python - this ain't one I'd say. Just read the output of netstat yourself,
and filter for lines that contain the desired pattern.

I would say that, according to documentation, the following should
work:
