| In the code below, why can i add elements to locals but not delete them?

from <URL: http://www.python.org/doc/lib/built-in-funcs.html#l2h-187>:

locals() 
      Return a dictionary representing the current local symbol
      table. Warning: The contents of this dictionary should not be
      modified; changes may not affect the values of local variables
      used by the interpreter.

this is because python doesn't (always) actually use a dictionary
internally to store local variables, to speed up execution.
