programming language(s) for bioinformatics

I am a high school sophomore and visited a professor in the molecular biology sciences who is also an expert programmer. (He builds robots, biochips, and a bunch of other cool gadgets.) In discussing other things, he urged me to learn Python programming, and now im very interested in computer science, and progressing rapidly. I know Python is a powerful language for its simple syntax. But if I want to go into bioinformatics (especially to use the tool http://www.ncbi.nlm.nih.gov/BLAST/) and computer programming in general, maybe even study cybersecurity, is it an ideal language to start with? or is C/C++ a better choice?

Those are all Scheme implementations, not CL.  Let's face it, aside from the visual appearance of the code, Scheme and CL are entirely different creatures.  Scheme is like C, simple and pure, and CL is like C++, badly designed and bloated.
