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

if __name__ == "__main__":
    words = ["cod", "s", "r"]
    print(verbing(words)) # expected ['coding', 'sing', 'ring']
    print(verbing(["work", "play"])) # expected ["working", "playing"]
    print(verbing(words)) # expected ['coding', 'sing', 'ring']

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 credit).

For full credit, include the type (Semantic error, Syntax error, or Runtime error) and cause of each bug. You don't need to say how fix the bugs and feel free to be 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 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 example, second_largest([20, -1, -10]) should return -1 and second_largest([8, 8, 7, 6, 5]) should return 8.

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. Hint: you do not need to sort the list to solve this problem!

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

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 test that was not explicitly provided
• /1 point - code correctness: second_largest function is implemented correctly

Solutions that use max, imports, sorted, or other similar advanced Python features can earn max half credit.
