I too took CS61AS in scheme and AI in python, but my experience was different than that of your friend. I didn't find it difficult to pick up python, and learning it after scheme made me appreciate python all the more.

Unless one plans on developing mostly in python during his or her career, I think its beneficial to be forced to learn multiple languages.

I've found that each incremental language I've learned typically improves my ability to write code in the languages I already 'knew'

It is definitely beneficial to learn multiple languages. I felt bad for my friend because she had taken the two concurrently.
