Uplоаd а Pythоn sоurce file (.py) thаt defines a function named transform. This function will take a list of dictionaries as its only parameter. This list contains dictionaries that each hold information about an ebay auction. The function will then return a single dictionary that will contain the same information but differently structured, as explained below. Let us start by putting the following code in your global scope: data = [ { 'name' : 'Atari Falcon 030', 'starting_price' : '499.99' }, { 'name' : 'Raspberry PI 400', 'starting_price' : '50.45' }, { 'name' : 'Lenovo T480', 'starting_price' : '200.59' }, { 'name' : 'Clockworks DevTerm', 'starting_price' : '259.95' }, { 'name' : 'HP DevOne', 'starting_price' : '759.85' } ] As you can see, the dictionaries in our list contain both the name of the items being listed (a string value corresponding to the key 'name' in that item's dictionary) and the starting price of the item (a string value corresponding to the key 'starting_price' in that item's dictionary). We want our function to return a dictionary in which the keys are the names of the items (we'll assume they are always unique) and the values are their respective starting price, as a float. With the example above, calling our function on the data variable would return a dictionary structured as follows: { 'Atari Falcon 030' : 499.99 , 'Raspberry PI 400' : 50.45 , 'Lenovo T480' : 200.59 , 'Clockworks DevTerm' : 259.95 , 'HP DevOne' : 789.85} You are free to add more code to the global scope of your file in order to call your function to test it. This extra code will not be graded but will help you ensure that your function performs as expected. Grading Rubric: The function creates an empty dictionary named result to start off with (1 point) The function iterates over the list correctly (1 point) The function correctly adds the content from each of the dictionaries in the list parameter, to the result dictionary (1 point) The function returns the correct result dictionary corresponding to the contents of the list passed as argument (1 point)
Cоnsider the fоllоwing dаtа structure: bookshelf = [ { 'title' : 'The Colour of Mаgic', 'author': 'terry pratchett', 'rating': 9, 'number_of_pages': 268 }, { 'title' : 'Dragonriders of Pern', 'author': 'anne mccaffrey', 'rating':8, 'number_of_pages': 256 }, { 'title' : 'The Hogfather', 'author': 'terry pratchett', 'rating': 10, 'number_of_pages': 404 }, {'title' : 'All the Weyrs of Pern', 'author': 'anne mccaffrey', 'rating': 7, 'number_of_pages': 312 }, { 'title' : 'Going Postal', 'author': 'terry pratchett', 'rating': 8, 'number_of_pages': 372 } ] Write a function named compute_stats that takes as first argument a list of dictionaries similar to the above, and a string representing the name of an author as second argument. It will return a tuple of two values: the first one will be the average rating (as a float) based on all books by that author found in the list. The second one will be the total number of pages of all books by that author found in the list. If the author passed as argument is not found in the books recorded in our list of dictionaries, then your function will return a tuple containing None and None. Please note that the author passed as argument may be spelled with a mixture of upper and lower cases and may have extraneous spaces at the beginning or end of the string. compute_stats(books, author_name) # returns a tuple containing: # the average rating (as a float) for all the books by that author # the total number of pages (as an int) for all the books by that author Grading Rubric: Iterates correctly over all books in the first parameter (1 point) Computes and return the average rating correctly (1 point) Computes and return the average rating correctly (1 point) Returns the two values as a tuple (1 point) Returns (None, None) when the author is not found (1 point) In the global scope, you call that function, then assign its two return values to two separate variables without having to use indexing (1 point)
Uplоаd а Pythоn sоurce file (.py) thаt defines a function named words_sorter. This function will take two strings as parameters. It will return a new string in which we have all the words from each of the string parameters, represented only once, and sorted in alphabetical order. Please note that, in the resulting string, the words will be separated by a comma followed by a space (as illustrated below). Examples: words_sorter('one two eight three four', 'five three six seven eight') will return 'eight, five, four, one, seven, six, three, two' words_sorter('', 'one two') will return 'one, two' words_sorter('two one', '') will return 'one, two' words_sorter('', '') will return '' You are free to add more code to the global scope of your file in order to call your function to test it. This part will not be graded but will help you ensure that your function performs as expected. Grading Rubric: 2 points for putting all words from the parameters in a list 1 point for removing duplicate words from that list 1 point for sorting the list 1 point for transforming that list of words into a string of words, each separated from the next one by a comma followed by a space. 1 point for passing the 4 tests mentioned above (0.25 each)
Write а functiоn print_mоde thаt tаkes nо parameter. It will prompt the user to enter some integer values and read a sequence of integers typed in a single line and each separated by a space character. All integers in the sequence must be between 0 and 10 (inclusive). If one or more values are out of range, display an error message for each value that is out of range and then read again a sequence of values from the user, until they get it right. If the user provides no value, display an error message and read again a sequence of values from the user, until they get it right. Once you have proper values, your function will identify and display on the screen the so-called mode of the series: that is, the value that appears the most often in the series of integers. If there is more than one value that could be the mode, your function has to display only one of them. Example of calling the function from the REPL: >>> print_mode()Enter some integers:ERROR - give me some values!Enter some integers:1 2 3 44 5 6 77 8ERROR - value 44 is out of range!ERROR - value 77 is out of range!Enter some integers:1 2 3 4 5 6 7 8Mode = 1>>> print_mode()Enter some integers:1 2 3 1 2 3 4 5 4 Mode = 1>>> print_mode()Enter some integers:1 2 3 1 2 3 4 5 4 8 4Mode = 4>>> Hint: Use a list to count the number of occurrences of each of the numbers between 0-10 in the user's sequence. Then find the max in this list: this is your mode. Grading Rubric: Reading all integers as one string and converting it to a list of int values (1 point) Using a loop to keep asking the user to enter a series of integers until they get it right (1 point) Displaying an error message if they entered no values (empty string typed) (0.5 point) Displaying an error message if any of the value is not between 0 and 10 (inclusive) (0.5 point) Being able to display an error message for each value that is out of range (1 point) Counting how many times each number between 0 and 10 appears in the sequence of values entered by the user (1 point) Using the above to identify and print the value of the mode (1 point) Displaying error messages exactly when and as illustrated above (0.5 point each, total 1 point)
