# dataset and then converts it into a dictionary! url.get_dictionary() does this for you from a csv/file on a page!
# Get contents just gets the text from a page as a big string. RETURNS BIG STRING! "..."
# Get dataset will return the csv as a list of lists (dataset). RETURNS LIST OF LISTS! [[],[],[]]
# Get dictionary will return a dictionary of the text file as a dictionary. RETURNS DICTIONARY! { k:v, k:v,...}

    # If you indent the translation accumulator update into else, it only add the wrong words to the translation.
    # Likewise, only indenting the translation accumulator update into if only adds the right words (the
    # words found in our dictionary to translate)
    # We want to add the translation of the word regardless of whether it's in our dictionary or not because
    # we have our translation as either the translation from the dictionary or the flagged word (?word?)!
    # EACH WORD HAS A "translation"

    # Hint: Use if/else the word is in our dictionary and see what we add to our translation :)
    # Remember: We wanna process each word in the user text word by word and get it's translation from the
    # dictionary if it exists and if it's not in our dictionary, it should be ?word? with the word!
    # What dictionary functions can we use?
    # Remember dictionaries look like { key: value, key : value, ...}

# print translation
