Python
Q1.
def silly(stuff, more_stuff=None):
    data = []
    for i, thing in enumerate(stuff):
        if thing >= 0 or i < 2:
            data.append(thing + i)
    print(len(stuff))
    if more_stuff is not None:
        data += more_stuff
    print(data)

Write a Python statement that calls silly and results in the output (from within silly):

4
[5, 3, 1, 5, -3]

stuff = [5, 2, 0, 2]
more_stuff = [-3]
silly(stuff, more_stuff)

Q2.

Function silly2 is defined as:

def silly2(nums, indices, extra=None):
    print(len(nums), len(indices))

    new_indices = []
    for i in indices:
        if i >= 0 and i < len(nums):
            new_indices.append(i)

    if extra:
        new_indices.append(extra)

    try:
        for index in new_indices:
            if index < len(nums):
                print(nums[index])
    except IndexError:
        print("We're dead, Fred")

Write a single Python statement that calls silly2 and results in the output:

2 2
We're dead, Fred

Answer 1

1)

CODE

def silly(stuff, more_stuff=None):

data = []

for i, thing in enumerate(stuff):

if thing >= 0 or i < 2:

data.append(thing + i)

print(len(stuff))

if more_stuff is not None:

data += more_stuff

print(data)

stuff = [5, 2, 0, 2]

more_stuff = [-3]

silly(stuff, more_stuff)

2)

CODE

def silly2(nums, indices, extra=None):

print(len(nums), len(indices))

new_indices = []

for i in indices:

if i >= 0 and i < len(nums):

new_indices.append(i)

if extra:

new_indices.append(extra)

try:

for index in new_indices:

if index < len(nums):

print(nums[index])

except IndexError:

print("We're dead, Fred")

nums = [1, 2]

indices = [0, 1]

silly2(nums, indices, -3)
