1,445 Pointsi did not understand how to unpack a dictionary, i have rewatched the video multiple times with no success
unpacking dictionaries, P.S. I have continued to the later parts of the series and everything is quite doable but the strategy i have been using is to put all the keys or values in a list and manipulate there. is this the right approach or am i missing some useful dict manipulation techniques by coercing everything to lists
def unpack (name=None,food = None):
return
def favorite_food(dict):
return "Hi, I'm {name} and I love to eat {food}!".format(name,food)

adict = {'a': 1, 'b': 2}
# **adict is then replaced with a=1, b=2
print("a is {a} and b is {b}".format(**adict))
# is the same as
print("a is {a} and b is {b}".format(a=adict['a'], b=adict['b'])
In the case of a parameter list such as def my_func(**kwargs):
, this means to expand the single dictionary object pass as an argument into separate key/value pair assigments.
