The os.system command neglects important changes in the environment

Thanks so much for your reply. You've definitely helped me a great
deal on this. Your comment about the difference between define time and
instantiation time cleared things up more than anything, and that also
helped clear up the confusion I was having about "self".

I'm trying to create a recursive function to evaluate the expressions
within a list. The function uses eval() to evaluate the list. Like a
lisp interpreter but very limited.
What I'm looking for is a function to recursively traverse the list and

existing Python code that will form part of the business logic. This
relies on 3rd party libraries (such as numpy) which would make porting
