Convert dictionary entries into variables [duplicate]

by

You can do it in a single line with:

>>> d = {'a': 1, 'b': 2}
>>> locals().update(d)
>>> a
1

However, you should be careful with how Python may optimize locals/globals access when using this trick.

Note

I think editing locals() like that is generally a bad idea. If you think globals() is a better alternative, think it twice! 😀

Instead, I would rather always use a namespace.

With Python 3 you can:

>>> from types import SimpleNamespace    
>>> d = {'a': 1, 'b': 2}
>>> n = SimpleNamespace(**d)
>>> n.a
1

If you are stuck with Python 2 or if you need to use some features missing in types.SimpleNamespace, you can also:

>>> from argparse import Namespace    
>>> d = {'a': 1, 'b': 2}
>>> n = Namespace(**d)
>>> n.a
1

If you are not expecting to modify your data, you may as well consider using collections.namedtuple, also available in Python 3.
