Passing dict to constructor?

Question

I\'d like to pass a dict to an object\'s constructor for use as kwargs.

Obviously:

foo = SomeClass(mydict)

Simply passes a single

Answer 1

Try this: SomeClass(**mydict)

Answer 2

Use :

foo = SomeClass(**mydict)

this will unpack the dict value and pass them to the function.

For example:

mydict = {'a': 1, 'b': 2}

SomeClass(**mydict) # Equivalent to : SomeClass(a=1, b=2)

Answer 3

To pass a dictionary to a constructor you have to do so by reference, which is by preceding it with **, like so:

foo = SomeClass(**mydict)
