1) Fun

For each of the following programs, enter the result of the print statement after executing the program.

If evaluating the print statement in question would cause an error, write error in the box.

x = 4

def fun(x):
    x = 1
    return x

y = 5
z = fun(y)

print([x, y, z])

def fun(x):
    y[0] += 1
    return x

y = [1, 2, 3]
x = [0]
z = fun(y)

print([x, y, z])

x = 5.5
y = 7.5

def fun(y):
    y += 2
    return bar(y)

def bar(x):
    x = x * 3
    return x

z = fun(10)

print([x, y, z])

2) Transcript

Below is a single Python program, split up into several pieces for viewing. After each print statement, provide the value that will be printed to the screen.

If evaluating the print statement in question would cause an error, write error in the box.

x = 14
y = 22
a = 12
b = 7

def f(x):
    return x + a

def f2(x):
    return y + b

a = 13

print(f(1))

print(f(a))

print(f2(a))

def f3(x, y):
    a = x + y
    return a + x + y

print(f3(43, 2))

print(a)
