Being able to code fast one-offs to solve problems or automate tasks is one of the strongest reasons to get into programming in the first place. This is hugely useful in engineering for example, not just in minimum wage grunt jobs. Scheme/Lisp facilitate this VERY poorly.

Python is maps far better to how problems are commonly presented, very rarely has gotchas that would make you drag out some advanced programming construct, and has batteries included at a level which scheme/lisp may NEVER catch up with:)

All of the world is not calculus! Spend all your time playing in that area and you won't become a very well rounded or capable programmer/engineer.
