00:00:39 *args example 1
00:03:10 *args example 2
00:04:32 **kwargs
00:07:51 exercise

# *args = allows you to pass multiple non-key arguments
# **kwargs = allows you to pass multiple keyword-arguments
# * unpacking operator

# ----- *ARGS Example 1 -----

def add(*nums):
total = 0
for num in nums:
total += num
return total

print(add(1, 2, 3, 4))

# ----- *ARGS Example 2 -----

def display_name(*args):
print(f"Hello", end=" ")
for arg in args:
print(arg, end=" ")

display_name("Dr.", "Spongebob", "Harold", "Squarepants", "III")

# ----- **KWARGS -----
def print_address(**kwargs):
for value in kwargs.values():
print(value, end=" ")

print_address(street="123 Fake St.",
pobox="P.O Box 777",
city="Detroit",
state="MI",
zip="54321")

# ----- EXERCISE -----
def shipping_label(*args, **kwargs):
for arg in args:
print(arg, end=" ")
print()

if "apt" in kwargs:
print(f"{kwargs.get('street')} {kwargs.get('apt')}")
elif "pobox" in kwargs:
print(f"{kwargs.get('street')}")
print(f"{kwargs.get('pobox')}")
else:
print(f"{kwargs.get('street')}")

print(f"{kwargs.get('city')}, {kwargs.get('state')} {kwargs.get('zip')}")
