Tuples and Nested Data¶

Tuples¶

# Also for return values
# Remember functions only return 1 value --
# With tuples, 1 value can hold multiple pieces of data

# Here's most of a function that takes a dictionary as input with
# key-value pairs that are names as keys
# and integers as values.
# The values represent the score that person got in a game.
# For example, {"Nick":12,"Ayo":15,"Lauren":21}

# The function should return a tuple:
# the name of the person who got the highest score, and their score

def highest_scoring(score_diction):
    keys = score_diction.keys() # could also use .items(), but that would lead to different code
    max_key_so_far = keys[0]
    for k in keys:
        if score_diction[k] > score_diction[max_key_so_far]:
            max_key_so_far = k
    # FILL IN THE RETURN STATEMENT

# example invocation code

sd = {"Nick":12,"Ayo":15,"Lauren":21}
sd2 = {"Natalie":62,"Jackie":35,"Jaime":44}

print(highest_scoring(sd)) # should print: Lauren 21
print(highest_scoring(sd2)) # should print: Natalie 62
# Like strings, tuples print a little different than they're represented in code

Nested Data¶

Exercise: Write a function that takes as input a list of lists, like x in earlier example, and returns a count of the total number of leaf items (seven in x above).
