Thanks for the sobering advice, and for the two sites I knew nothing about. So there's a SciPy!

Of course, but coding general-purpose root finders-- even if "general"
is limited to just polynomials --requires mathematical and numeric
expertise.  If it interests you, there are book-length treatments of
the subject, and there's really no easy reliable approach.  Good
online sources for numeric algorithms include:

Just Googling on

    polynomial roots Python

will point you to
