Python double asterisk that is not **kwargs but rather gets used on the function call itself

Question

was watching here:

https://youtu.be/F5mRW0jo-U4?t=9267

he proceeds to write the call:

Product.objects.create(**my_form.cleaned_data)

Can someone explain what is the difference between

Product.objects.create(my_form.cleaned_data)

and

Product.objects.create(**my_form.cleaned_data)

Answer 1

Assuming that my_form.cleaned_data is a dict, or some other kind of mapping, then create(**my_form.cleaned_data) will pass all the dict's entries as keyword arguments. So:

def my_fun(a=None, b=None):
    print(a)
    print(b)

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

my_fun(**my_dict)

would print:

1
2
