Lesson 6 Dictionaries

Lesson 6 Dictionaries was very good for today.
I am very happy to have learned Dictionaries in Python Programing at this great institute/organization ILabLiberia.
Prof Zane was good to us in this class.
Below are some practice of this lesson.

# Exercise 0 : This Next Part is Key
"""
    Print the value stored under the 'Sloth' key
    Print the value stored under the 'Burmese Python' key.
"""
residents = {'Puffin' : 104, 'Sloth' : 105, 'Burmese Python' : 106}


# Print the value stored under the 'Sloth' key
print residents ["Sloth"]



# Print the value stored under the 'Burmese Python' key
print residents ["Burmese Python"]






# Exercise 1 : New Entries
"""
    Add at least three key-value pairs to the menu variable,
    with the dish name (as a "string") for the key and the
    price (a float or integer) as the value. Here's an example:

    menu['Rice'] = 2.50
"""

menu = {}
menu['Chicken'] = 14.50


# Add three dish-price pairs to menu!
menu['Fish'] = 10.50
menu['Pizza'] = 17.50
menu['Rosted Meat'] = 10.99
print menu






# Now print the menu to see the new items





# Exercise 2 : Changing Your Mind
"""
    Delete the 'Sloth' and 'Bengal Tiger'
    items from zoo_animals using del.

    Set the value associated with 'Rockhopper Penguin'
    to anything other than 'Arctic Exhibit'.
"""

# key - animal_name : value - location
zoo_animals = { 'Unicorn' : 'Cotton Candy House',
'Sloth' : 'Rainforest Exhibit',
'Bengal Tiger' : 'Jungle House',
'Atlantic Puffin' : 'Arctic Exhibit',
'Rockhopper Penguin' : 'Arctic Exhibit'}

del(zoo_animals['Unicorn'])

print zoo_animals



# Delete the 'Sloth' and 'Bengal Tiger' items from zoo_animals using del.
del (zoo_animals ['Sloth'])

del (zoo_animals ['Bengal Tiger'])

print zoo_animals



# Set the value associated with 'Rockhopper Penguin' to something else.
zoo_animals ['Rockhopper Penguin'] = 'Lion Dane'


# Now print this zoo_animals dictionary
print zoo_animals
