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 Inputkeyl : value1, key2 : value2, key3 : valuelSample Output{ "valuel" : ["keyl", "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 OutputThose strings are anagrams.Sample Inputevillive5. On some basic cell phones, text messages can be sent using the numeric keypad.Because each key has multiple letters associated with it, multiple key presses areneeded for most letters Pressing the number once generates the first character listed

Assume a Dictionary structure has been defined that associates letter grades to their respective integer "quality point" values used for calculating a student's grade point average. The name of the structure is gradePoints. Write a statement to retrieve the quality point value for a letter grade of "C". Store the retrieved value in a variable named "qPoints".
13. While dictionaries are designed so that we can find a value based on a key, every so often we need to perform a reverse lookup. For example, imagine a dictionary where the keys are names and the values are phone numbers. Usually we want to find the phone number based on the name, but occasionally you might need to find a name based on the phone number. Write a function called reverse_lookup(dictionary, value) that returns all the keys in the dictionary associated with the specified value. Note: In dictionaries, the keys are guaranteed to be unique, but the values are not. So your function should return a list containing all of the matching keys (if any) Example: Given this dictionary, groups = {'Apple': 'Fruit', 'Spinach': 'Vegetable', 'Banana': 'Fruit'} reverse_lookup (groups. Vegetable') ["Spinach'] reverse_lookup (groups, Fruit') ['Apple'. 'Banana'] reverse_lookup (groups. 'Meat') []
In python make a function with the parameter of a dict[str, str] the function will simply invert the dictionary do not use .get, .item, .values, or import builtins If you encounter more than one of the same key when trying to invert the key and value, raise a keyerror for example ['john': 'white', 'garcia': 'white'], should trigger the raise KeyError call
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…
Please answer the ques in python with showing the answers. Q: A car dictionary: a) Implement a dictionary car with the keys brand, model, and color. Give appropriate values for each key (you choose). b) Print each item in the dictionary (see example output) c) Add a key transmission to the dictionary with the value ‘automatic’. d) Print the value for the key transmission (use the get method). Output Example: subaru crosstrek sapphire blue automatic
I am struggling with this program question for the last few hours. Could you please assist? Write a program that prompts user to enter make, model, color and year of their car. Store the input data in a dictionary and a list. The dictionary has "make", "model", "color", and "year" as keys. The dictionary values are user inputted data. In addition, store the input data in a list also. Store the make, model, color and year of the car in a list. Display the dictionary and list. Here are sample program run. Your program output message should be similar to below. Make sure use other inputs to verify the correctness of the program. What is the make of your car? Ford What is the model of your car? Taurus What is color of your car? white What is the year of your car? 1997 Car info dictionary: {'make': 'Ford', 'model': 'Taurus', 'color': 'white', 'year': 1997} Car info list: ['Ford', 'Taurus', 'white', 1997] (I am getting syntax errors all over the place) I do have tutoring sessions but I'm in…
Problem 2-Python We have a dictionary where the keys are the names of all your relatives and the values are their ages. Write a Python program to iterate/loop over the dictionary and find the oldest member of your family. Sample output: The oldest relative is Helko. Recall: Iterating over a dictionary iterates over its KEYS. HINT: First we initialize maximum_age to 0 and maximum_age_relative to and empty string. These variables will be updated during the loop. Then we need to iterate over the keys of the dictionary my_family to find the member and their age.If the age is greater than the current maximum_age, we update maximum_age with this new maximum age. Then we update the maximum_age_relative with the new member. Given Code: my_family = {'Bob':72, 'Susan':39, 'Helko':81, 'Gertrude':4} maximum_age = 0 maximum_age_relative = ""
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..
Please code this in C++. Do not use namespace std. Please use basic code. Thank you for your time.
