With the Tcl expect I would advise:

I assume you're trying to match the prompt, and the colour codes are messing you up. I'd keep it as simple as possible: match the angle bracket and space at the end of input:
expect -re {> $}

With python's telnetlib, it appears that read_until does not work with a regular expression. I wonder if this will be sufficient:

self.teln.read_until('[0m> ', 300)

Perhaps you want read_eager() or read_very_eager() instead.
