Consider the below program, separated into pieces. Indicate the value of the prompted expressions. If evaluating the expression would cause an error, write error in the box. If an expression is a function, write function in the box. If an expression is a string, make sure to wrap it in quoatation marks.
An environment diagram may be particularly helpful here. Relevant readings include the custom function example from unit 4
three = "three"
def one():
one = 1
two = 2
three = 3
return 1
a = one()
print(three)
What's the value of a?
What's the value of three that will be printed in the last line?
def two():
return 2
one = two
two = one
b = one()
c = two
What's the value of b?
What's the value of c?
