Ana,

Great job on this lab!

It is always a good idea to test our own functions, but your tests on questions 2,3,5 and 7 gave you errors because the functions were created to get lists as arguments and you weren’t passing your arguments as lists.

For instance, in question 2, you ran:
greatest(2,3,4,2) #you are missing the square brackets used to define a list on Python
Instead of greatest([2,3,4,2])

On question 3, it should be sum_all([4,9,8,20])

On question 4: mult_all([9,2,6,7[)

On question 5, your function had two arguments: a list and a string that could be either “+” or “*”. You ran:
oper_all[9,2,4,5],("*")
Instead of
oper_all([9,2,4,5],"*") # [9,2,4,5] is a list and “*” is a string and both arguments need to be inside the parenthesis ( )

In that same question, you need to delete the asterisk before arr for the function to work properly and pass the test.

On question 7, it should be: unique([2,2,2,5])

About the bonus questions, a possible solution to question 11 would be to create a dictionary were the keys are the words of your list and the values are the frequency of each word. Then, you just look for the highest value:

def mode_counter(arr):
    dict_arr = {}
    for element in arr:
        dict_arr[element]=0
    for element in arr:
        index = [i for i,e in enumerate(arr) if e == element]
        dict_arr[element]=len(index)
    max_count = max(dict_arr, key=dict_arr.get)
    return max_count

For question 12:

def sort_alpha(input_string):
    # Initialize an empty list to store the words
    words = []

    # Initialize variables to keep track of the current word
    current_word = ""
    is_inside_word = False

    # Iterate through each character in the input string
    for char in input_string:
        if char == ',':
            # If a comma is encountered, append the current word to the list
            if is_inside_word:
                words.append(current_word)
                current_word = ""
                is_inside_word = False
        else:
            # Add the character to the current word
            current_word += char
            is_inside_word = True

    # If there's a word left after the loop, append it to the list
    if is_inside_word:
        words.append(current_word)

    # Sort the list of words alphabetically
    words.sort()

    # Create a sorted string by joining the sorted words with commas
    sorted_string = ""
    for word in words:
        sorted_string += word + ","

    return sorted_string[:-1]
