modifying variables in local or global space

[fishhook]

you can't modify variables in local space using they dictionary you get from locals()

but.... I can

>>> l=locals()
>>> l["foo"] = "bar"
>>> print(locals())
{'__spec__': None, '__builtins__': <module 'builtins' (built-in)>, '__name__': '__main__', '__loader__': <class '_frozen_importlib.BuiltinImporter'>, 'foo': 'bar', '__package__': None, '__doc__': None, 'l': {...}}
