Can Python replace TCL/Expect

[xinchenvn@gmail.com]

Hi

I'm learning Python. I don't know whether Python can do something like
Expect can do. If yes, please show me how to do it.
I want to do something automatically: open connection to a ftp server,
get the welcome message on the screen (not in the packet). I can do it
easily with Expect but I still don't have any idea with Python.
If possible, can you introduce me some book or website that I can get
infor about automation programming with Python

Thanks

You'll probably want to take a look at pexpect:

http://pexpect.sourceforge.net/

It depends. I do not feel /that/ advanced, but I've been bitten by pexpect's
limitations several times in several places.

.... which puts me in a weird position ;-) I /loathe/ the Tcl language, but I
have to admit that its expect functionality is far superior to Python's.

There is hobby hacking, and there is work. I've encountered pexpect during
work, and haven't had the time and energy to look into it. I hereby
apologize to the pexpect developers. Not for whining, but for not helping
out.
