This small quiz is just for validating the concepts covered during the first week of our course. It's not something you can pass or fail. We use the results of this quiz to evaluate if we need to add more support sessions or improve any aspect of the course.
PLEASE, don't cheat. Make it honest. We'll never share the data with the rest of the class.

Take a look at the following code and answer:
a = 10
b = 3
c = 7
def test_scope(b):
a = 11
return a + b + c
c = c + test_scope(5)What will be the final value of the variable c?
a) 23
b) 30
c) 29
d) 28
e) None # The function gets into an infinite loop
IMPORTANT: Return the actual value as shown in the options. DO NOT surround it with quotes. Example, if you think that 23 is the correct answer, you should put return 23. Again, DON'T use quotes, and DON'T use the option number (return a, return "a)", return "a", etc).
Write a function number_of_customers_per_state that receives a dictionary containing states (as keys) and customers for those states (as a list of dictionaries) and returns a final dictionary containing the count of customers per state.
Example:
customers = {
'UT': [{
'name': 'Mary',
'age': 28
}, {
'name': 'John', # Eldest
'age': 31
}],
'NY': [{
'name': 'Linda', # Eldest
'age': 71
}]
}
number_of_customers_per_state(customers)Should return:
{
'UT': 2,
'NY': 1
}Write a function eldest_customer_per_state that receives a dictionary containing states (as keys) and customers for those states (as a list of dictionaries) and returns a final dictionary containing the eldest customer per each state.
Example:
customers = {
'UT': [{
'name': 'Mary',
'age': 28
}, {
'name': 'John', # Eldest
'age': 31
}],
'NY': [{
'name': 'Linda', # Eldest
'age': 71
}, {
'name': 'Lisa',
'age': 25
}]
}
eldest_customer_per_state(customers)Should return:
{
'UT': {
'name': 'John',
'age': 31
},
'NY': {
'name': 'Linda',
'age': 71
}
}
