Fun fact, it can be done, but it's (afaik) then (almost) unusable...

 >>> a
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
NameError: name 'a' is not defined
 >>> locals()['a'] = 42
 >>> a
42
 >>> locals()[''] = 42
 >>> locals()['']
42
 >>> locals()[''] = (lambda x: x*42)
 >>> locals()[''](1)
42
