   Seems you are a novice, just doing your first steps in Python! Welcome! :)

   "indices=indices" is not an expression at all - it is an assignment. The
"lambda" constructs a function in the global namespace, and the function
doesn't have access to local var "indices". The assignment give such
access.

   It is from LISP, well-known programming language.
