1. Write a function invert_dict to reverse a dictionary, for example: >>> eng2sp = {'one': 'uno', 'two': 'dos', 'three': 'tres'} >>> sp2eng = invert_dict(eng2sp) >>> sp2eng {'uno':'one', 'dos':'two', 'tres':'three'} 2. Write a function print_dict to print all the key-values in a dictionary, for example: >>> d2 {'a': 'one', 'b': 'two', 'c': 'Three'} >>> print_dict(d2) a:one b:two c:Three

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…
Assume the variable definitions references a dictionary. Write an if statement that determines whether the key 'marsupial' exists in the dictionary. If so, delete 'marsupial' and its associated value. If the key is not in the dictionary, display a message indicating so.

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…

Exercise: Check Monster Character Exists Description In this series of exercises, you will create functions to create, modify and examine dictionaries that represent characters in an animated film, and the cast members who voice the characters. The keys of the dictionary will be character names. The values in the dictionary will be voice actor names. For this exercise, you will create a function that checks if a character is already in the dictionary. Files monsterfunctions.py : set of functions to work with monster cast dictionaries. Function Name has_character Parameters monsters: a dictionary character: a string, the name of a character Action Checks if character is a key in monsters. Return Value True if character is a key in monsters, otherwise False. Examples monsters = create_monster_cast() monsters = add_cast_member(monsters, "Mike", "William Crystal") has_character(monsters, "Mike") -> True has_character(monsters, "Sully") -> False
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.
