I suspect that Peter said what he did, because your code wouldn't work 
anyway.

From the manual:
    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. 

Note the warning.

And a quick experiment

$ cat foo.py
def foo():
    some_dict= {'before':'new value',
                'after':'some other value' }
    before='this is the value before trying to update locals()'
    locals().update(some_dict)
    print before
    print after

foo()
$ python foo.py
this is the value before trying to update locals()
Traceback (most recent call last):
  File "foo.py", line 9, in <module>
    foo()
  File "foo.py", line 7, in foo
    print after
NameError: global name 'after' is not defined
