Second Largest

1) Part 1

Larry has written the following piece of code, designed to solve the first part of the ing assignment from week 2.

def verbing(worsd)
    """
    This function should take in a list of strings and return a new list of strings with "ing" added to the end of each word.
    """
    for w in len(words):
        words[w] = w + "ing"
    return words

words = ["cod", "s", "r"]
print(verbing(words)) # expected ['coding', 'sing', 'ring']
print(verbing(["work", "sleep", "play"])) # expected ['working', 'sleeping', 'playing']

Sadly, there are bugs in the code above exactly as written. Please describe any bugs you can find (there are 5 main bugs, but finding fewer will still get partial credit).

For full credit, include the type (Semantic error, Syntax error, or the specific runtime error) and cause of each bug. You don't need to say how fix the bugs and feel free to be very brief (1-2 sentences per bug).

For example, one of the five bugs is that "In line 1, Larry forgot the colon ":" at the end of the definition of the verbing function, which causes a SyntaxError".

2) Part 2

In a file on your own machine, write and test a function called second_largest_number that takes as input a single list containing 0 or more numbers. If there are 0 or 1 numbers in the given list, your function should return None. Otherwise, it should return the second largest number in the list.

For full credit, your code should not use built-in functions such as max or sorted. It should also not mutate (change) the input list.

You do not need to handle the case where elements in the provided list are not numbers.

For example, running the following code:

print(second_largest_number([]))
print(second_largest_number([2]))
print(second_largest_number([94, 87, 20, 35]))
print(second_largest_number([20, -1, -10]))
print(second_largest_number([8, 8, 7, 6, 5]))

should print:

None
None
87
-1
8

Pay particular attention to the last example. It does not print 7 since 8 is both the largest and second largest number.

Start by making a plan and running through some test cases of your own devising on paper. Once you are confident in your plan, implement your function and test using the Python interpreter. When you are ready, submit your file twice below. In order to get manual style credit, your code must pass at least half of the automated tests in the second file submission below.

Please upload your code here. This question will be manually graded for good code style according to the following rubric / 5 points:

• /1 point - function has descriptive docstring
• /1 point - use of good variable names, comments are added if needed
• /1 point - code clarity: code is easy to read, generally follows normal Python style conventions.
• /1 point - code testing: code has an if __name__ == '__main__': block which includes at least 1 manual test case that uses an f-string
• /1 point - code complexity: code avoids unnecessary repetition, overly complex logic

Solutions that use max, imports, sorted, or other similar advanced Python features can earn max half credit (the point of this exercise is to help you to develop your programming skills by writing the explicit logic yourself!)
