#1 Basics of dictionaries

'''fruitbasket = { "apple":3, "banana":5, "cherry":50 }

print(fruitbasket["cheery"])'''

#1.1 use for loop:

'''fruitbasket = { "apple":3, "banana":5, "cherry":50 }

for key in fruitbasket:

print("{}:{}".format(key, fruitbasket[key]))'''

#1.2 Access a dictionary element using a key

'''fruitbasket = { "apple":3, "banana":5, "cherry":50 }

print(fruitbasket)

fruitbasket["mango"] = 1

print(fruitbasket)'''

#1.3 Deleting an item from a dictionary using del keyword:

'''fruitbasket = { "apple":3, "banana":5, "cherry":50 }

print(fruitbasket)

del fruitbasket["banana"]

print(fruitbasket)'''

#2 Dictionary Methods:

#2.1 copy()

'''fruitbasket = { "apple":3, "banana":5, "cherry":50 }

fruitbasketalias = fruitbasket

fruitbasketcopy = fruitbasket.copy()

print(id(fruitbasket))

print(id(fruitbasketalias))

print(id(fruitbasketcopy))'''

#2.2 keys(), values(), and items()

'''fruitbasket = { "apple":3, "banana":5, "cherry":50 }

print(list(fruitbasket.keys()))

print(list(fruitbasket.values()))

print(list(fruitbasket.items()))'''

#2.3 use for loop max(), min(), sum().

'''fruitbasket = {"apple":3, "banana":5, "cherry":50, "durian":0, "mango":2}

for key in fruitbasket.keys():

print("{}:{}".format(key, fruitbasket[key]))

print(sum(fruitbasket.values()))'''

#2.4 get()

'''fruitbasket = { "apple":3, "banana":5, "cherry":50, "durian":0, "mango":2 }

apple = fruitbasket.get("apple")

if apple:

print("apple is in the basket")

else:

print("no apples in the basket")

orange = fruitbasket.get("orange")

if orange:

print("orange is in the basket")
