# 1) Create a tuple called olympics with four elements: “Beijing”, “London”, “Rio”, “Tokyo”.

# Amswer:

olympics = "Beijing", "London", "Rio", "Tokyo"



# 2) The list below, tuples_lst, is a list of tuples. 
# Create a list of the second elements of each tuple and assign this list to the variable country.

# Amswer:

tuples_lst = [('Beijing', 'China', 2008), ('London', 'England', 2012), ('Rio', 'Brazil', 2016, 'Current'), ('Tokyo', 'Japan', 2020, 'Future')]
country = []

for scnd_elem in tuples_lst:
    country.append(scnd_elem[1])
    
print(country)



# 3) With only one line of code, assign the variables city, country, and year to the values of the tuple olymp.

# Amswer:

olymp = ('Rio', 'Brazil', 2016)
city, country, year = olymp



# 4) Define a function called info with five parameters: name, gender, age, bday_month, and hometown. 
# The function should then return a tuple with all five parameters in that order.

# Amswer:

def info(name, gender, age, bday_month, hometown):
    return name, gender, age, bday_month, hometown

print(info('myself', 'male', 33, 'July', 'Buenos Aires')) # print is not needed for excersise

# 5) Given is the dictionary, gold, which shows the country and the number of gold medals they have earned 
# so far in the 2016 Olympics. Create a list, num_medals, that contains only the number of medals for each 
# country. You must use the .items() method. Note: The .items() method provides a list of tuples. 
# Do not use .keys() method.

# Amswer:

gold = {'USA':31, 'Great Britain':19, 'China':19, 'Germany':13, 'Russia':12, 'Japan':10, 'France':8, 'Italy':8}
num_medals = []

for how_many in gold.items():
    num_medals.append(how_many[1])
print(num_medals)
