3. Write python code to invert a dictionary. It should print a dictionary where the keysare values from the input dictionary and the values are lists of keys from the inputdictionary having the same value. Make sure the program handles multiple samevalues.Sample Inputkey1: valuel, key2 : value2, key3 : valuelSample Output{ "value1" : ["key1", "key3"], "value2" : ["key2"] }4. Two words are anagrams if they contain all of the same letters, but in a differentorder. For example, "evil" and "live" are anagrams because each contains one "e",one "i", one "l", and one “v".Write a program that reads two strings from the user and determines whether or not theyare anagrams. Use a dictionary to solve the problem.Sample InputSample OutputThose strings are anagrams.evillive Dictionary & Tuple1. Write a Python program to combine two dictionaries into one by adding values forcommon keys. Input contains two comma separated dictionaries. Print the newdictionary and create a tuple which contains unique values in sorted order.Sample Inputа: 100, b: 100, с: 200, d: 300а: 300, b: 200, d: 400, e: 200Sample Output{'a': 400, 'b': 300, 'c': 200,'d': 700, 'e': 200}Values: (200, 300, 400, 700)6.2. Write a python program which prints the frequency of the numbers that weregiven as input by the user. Stop taking input when you find the string "STOP". Donot print the frequency of numbers that were not given as input. Use a dictionaryto solve the problemSample InputSample Output10 - 2 times102020 - 2 times2030 - 1 times50 - 1 times90 - 1 times30105090STOP

Dictionary & Tuple 1. Write a Python program to combine two dictionaries into one by adding values for common keys. Input contains two comma separated dictionaries. Print the new dictionary and create a tuple which contains unique values in sorted order. Sample Input а: 100, b: 100, с: 200, d: 300 а: 300, b: 200, d: 400, e: 200 Sample Output {'a': 400, 'b': 300, 'c': 200,'d': 700, 'e': 200} Values: (200, 300, 400, 700)

Question-2: Write a Python program that takes a string as an input where multiple numbers are separated by hashes(#). Your first task is to create a list of numbers and print it. Your second task is to create a dictionary that will have the index of the list as key, and for the even indices, multiplication from start to that index as value, while for the odd indices, summation from start to that index as value. Finally, print the dictionary. . ================================================ Sample Input 1: 1#2#3#4 Sample Output 1: [1, 2, 3, 4] {0: 1, 1: 3, 2: 6, 3: 10} Sample Input 2: 5#6#7 Sample Output 2: [5, 6, 7] {0: 5, 1: 11, 2: 210}
Modify the following program to read dictionary items from a file and write the inverted dictionary to a file: characters = {'Bugs':['Rabbit', 1940, 'boy'], 'Garfield': ['Cat', 1978, 'boy'], 'Tweety': ['Bird', 1942, 'girl'], 'Sandy': ['Squirrel', 1999, 'female']} print("Printing the original dictionary") print(characters) print("") def invert_dict(characters): inverse = dict() for key in characters: val = characters[key] for list_item in val: if list_item not in inverse: inverse[list_item] = [key] else: inverse[list_item].append(key) return inverse my_invert = invert_dict(characters) print("Printing the inverted dictionary") print(my_invert) Include the following: 1) The input file for your original dictionary (with at least six items).2) The Python program to read from a file, invert the dictionary, and write to a different file.3) The output file for your inverted dictionary.…
Load the JSON file below into Python as a dictionary; convert to a list and calculate the minimum velocity and maximum height using recursion. Introduce the space mission to the user and ask the user to guess a minimum velocity and maximum height, which the code should use as start points. Print the results (min & max to a file, and at the end read the file to display the results on the screen) This is partial data from the space mission Jason-3, flight number 26

Program - Python Make a dictionary, the student's name is the key (a string) and the student's test scores is the value (a list). So it should be a dictionary with six key value pairs in it. Here is data to use. Brian,94,89,92 Rachel,100,90,65 Jon,67.5,95,100 Brit,0,78,80 Greg,65,100,78 Andrea,55.5,67,79 Now print the dictionary data using a loop that starts with for key, value in.

In python: student_dict is a dictionary with students' name and pedometer reading pairs. A new student is read from input and added into student_dict. For each student in student_dict, output the student's name, followed by "'s pedometer reading: ", and the student's pedometer reading. Then, assign average_value with the average of all the pedometer readings in student_dict..

Can you please answer the following? Program is in Python and needs to look EXACTLY like the example attached. Thank you! 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…
Write a Python program that takes a dictionary as an input and then outputs the average of all the values in the dictionary. [You are not allowed to use len() and sum()] =================================================================== Hint: you can use dictionary functions to get all the values from it, run loop to calculate the sum and the total number of values in the dictionary in order to find out the average. def task8(dict_in): # YOUR CODE HERE return str_out result must say Avarge is whatever number is please use dict _ in and str_out as values also same format for function str_out must be assigned to final result it cant have print function in it
Please answer it in Python In order not to forget to wish the birthday of his loved ones, Alzheimer wants to memorize and manage their dates of birth via a computer program in Python. At first, it is assumed that Al has already computerized the birthday dates of his relatives in a dictionary. The keys in this dictionary are the first names of his relatives (it is assumed that no two people with the same first name). The value associated with each key corresponds to the birthday of the corresponding person, in the form of a 3-item list, containing in the order the day, month and year of birth. The day is considered to be an integer between 1 and 31, the month an integer between 1 and 12 and the year of birth an integer between 1900 and 2021. Thus the list [17, 5, 2021] corresponds to the date of May 17, 2021. This may lead to writing dates that do not exist (e.g. [31, 4, 2003]) but this is not addressed in the exercise. Here is an example of a dictionary containing the dates of birth of…
