In the following code, what is true about tax after amount = calculate_total(100, 0.08)?

def calculate_total(price, tax_rate):
tax = price * tax_rate
total = price + tax
return total

A
tax is local to calculate_total and is not directly accessible outside it.
B
tax is global because it is used in an arithmetic expression.
C
tax is automatically returned along with total.
D
tax can be accessed outside the function because all Python variables are global.

How should this function be classified?

def add_score(scores, new_score):
scores.append(new_score)

A
It is pure because it accepts a list parameter.
B
It is pure because it performs only one operation.
C
It has no effect because it does not return a value.
D
It has a side effect because it modifies the caller's list.
