How to input the following code # Open the input file and read the dictionary with open("books.txt", "r") as file: favorite_books = {} for line in file: title, author, year = line.strip().split(", ") favorite_books[title] = [author, int(year)] # Invert the dictionary using the function from the previous program def invert_dict(d): inverse = dict() for key in d: vals = d[key] for val in vals: if val not in inverse: inverse[val] = [key] else: inverse[val].append(key) return inverse inverted_dict = invert_dict(favorite_books) # Write the inverted dictionary to a file with open("inverted_books.txt", "w") as file: for key, value in inverted_dict.items(): file.write(str(key) + ": " + str(value) + "\n")

This section has been set as optional by your instructor. OBJECTIVE: Write a program in Python that prints the middle value of a dictionary's values, using test_dict from the test_data.py module. NOTE: test_dict is created & imported from the module test_data.py into main.py Example 1: test dict = {'a':1,'b':9,'c':2,'d':5} prints 5 Example 2: test_dict = {'b':9,'d':5} prints 5 Hint: You may(or may not) find the following function useful: list.sort() which sorts the elements in a list. Note: the result is automatically stored in the original list, and return value from the function is None Туре list = [1, 2,3,2,1] After calling: list = [1,1,2,2,3] list.sort(), 339336.2266020 x3zgy7 LAB 13.11.1: Middlest Value (Structured Types) АCTIVITY 0/11 File is marked as read only Current file: test_data.py 1 #This module creates the test_dict to be used in main.py 2 #Reads input values from the user & places them into test_dict 3 dict_size = int(input()) #Stores the desired size of test_dict. 4...

PYTHON QUESTION This assignment requires you to create a dictionary by reading the text file created for the Chapter 6 assignment. The dictionary should have player names for the keys. The value for each key must be a two-element list holding the player's goals and assists, respectively. See page 472! Start with an empty dictionary. Then, use a loop to cycle through the text file and add key-value pairs to the dictionary. Close the text file and process the dictionary to print the stats and determine the top scorer as before. In fact, much of the code used in program6_2.py can be copied and used for this program. Printing the stats for each player is the most challenging part of this program. To master this, refer to the examples in the zip file that can be downloaded from the "Dictionary values can be lists" link in the "Learn Here" part of this module. NOTE: you do not need to submit the text file. Submit just this program. The required output should be the same well-formatted table...

As part of this assignment, the program that you will be writing will store current grades in a dictionary using course codes as keys and with values consisting of percent grades in lists. The main functions of this program are to print a student's gradebook, to drop the lowest grade in each course, print the student's gradebook again, drop the course with lowest average, and finally printing the student's gradebook again. This program requires a main function and a custom value-returning function. In the main function, code these basic steps in this sequence (intermediate steps may be missing): start with an empty dictionary that represents a gradebook and then use a while loop to allow the input of course codes from the keyboard. End the while loop when the user presses enter without entering data.within the while loop:for each course entered, use a list comprehension to generate five random integers in the range of 70 through 100. These random integers in a list represent the...

This code is full of errors, what are 4 of them and how I would fix them?

Assume the following list exists: names = ['Chris', 'Katie', 'Joanne', 'Kurt'] Write a statement that uses a dictionary comprehension to create a dictionary named X in which each element contains the length of a name from the list as the key, and the corresponding name's initial character as its value.

Overview This is a review assignment where you will use multiple tools you have picked up so far throughout the course. If you're confused about how to do something make sure you look back at earlier assignments. In this program you will start by declaring an empty dictionary named population_dict. Then you will use a while-loop to prompt a user for a series of cities and their populations, storing the input in population_dict). After this you will prompt the user to decide what is the maximum population for a city to be considers a small down. Finally, you will open a file called populationdata.txt where you will write the results. Expected Output Example of standard out (the console): What is next city? (enter q to quit) Long Beach What is the population of Long Beach? 362000 What is next city? (enter q to quit) Los Angeles What is the population of Los Angeles? 382000000 What is next city? (enter q to quit) San Diego What is the population of San Diego? 136000000 What is next city?...
