Full Stack JavaScript Techdegree Graduate 29,854 PointsHow do you pack a dictionary into a function?
In the 'Packing with Dictionaries' video, the instructor packs a sequence of variables and arguments (i.e. name='Doug') into a function using **kwargs. The title of the video is misleading as it doesn't actually pass a dictionary into the function. How do you actually pass each element of a dictionary into a function?

example_dictionary = {
'name' : 'user',
'role': 'pythonista'
}
def example_print_info_for(name, role):
print(f"My name is {name}, and I am a {role}")
you then use the double asterisks (**
) before the dictionary name when calling the function i.e.
example_print_info_for(**example_dictionary)
You should get the output
My name is user, and I am a pythonista
