locals() should be considered read-only. From the docs:

locals(  	)
     Update and 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.

At global scope, locals() == globals() and modifying locals() will work. 
Within a function, modifying locals() will not do what you want.
