loading a dictionary

[Skaperen]

i get a dictionary returned from a function call. this is a bunch of variable name keys and new values for them. there are a lot of them and a very large set of variables that could be changed. i could do this by creating and loading a module using the * selection. is there a better way to do this?

Is this what you're looking for? The code below will assign values to variables according to the corresponding values in the dictionary.

tester = {'a': 7, 'b': 13, 'c': 144}

for key, value in tester.items () :
	exec (f'{key} = {value}')

print (a, b, c)

At global level, you could do

globals().update(thedict)

In a class definition, you could do

locals().update(thedict)

Don't do that inside a function's body with the locals() dictionary: it won't work as you expect.

Similarly, you cannot import * inside a function's body.

Why do you want to update many variables from a dictionary?

[Skaperen]

they are return values. there are just a lot of them. too many to make a tuple-like assignment. and the caller won't know which are really updated.

[Gribouillis]

You could simply update an instance's dictionary

>>> class Namespace: pass
...
>>> ns = Namespace()
>>> ns.__dict__.update({'a': 1, 'b': 10})
>>> 
>>> ns.a
1
>>> ns.b
10
