Need help in passing a "-c command" argument to the interactiveshell.

[Bill]

On my windows box I type => c:\x>python -c "import re"

The result is => c:\x>

In other words, the Python interactive shell doesn't even open. What
am I doing wrong?

I did RTFM at http://www.python.org/doc/1.5.2p2/tut/node4.html on
argument passing, but to no avail.

Nothing! =) The -c option tells Python to execute the commands in the
quotes as a Python program. It's as if you wrote a Python program that
contained only "import re" and then executed that program.

If you want to run the Python interpreter interactively, just type
"python" (no quotes) at the command prompt and hit enter.

I did RTFM at http://www.python.org/doc/1.5.2p2/tut/node4.html on
argument passing, but to no avail.

Yikes, that's the documentation for Python 1.5.2 which is nine years
old! If that's the version you're running, then it's appropriate to
read that documentation, but that's probably not the case.

"python --version" (again, no quotes) should tell you what version
you're running.

You've told python to run the command "import re" which it's happily
done before exiting. Simply type python, then at the prompt (default
