- Capital QuizWrite a program that creates a dictionary containing the U.S. states as keys, and their capitals as values. (Use the Internet to get a list of the states and their capitals.) The programshould then randomly quiz the user by displaying the name of a state and asking the userto enter that state’s capital. The program should keep a count of the number of correct andincorrect responses. (As an alternative to the U.S. states, the program can use the names ofcountries and their capitals.) in phytonarrow_forwardAssume that d refers to a dictionary. Write a statement in Python that retrieves from the dictionary the value that is associated with the key 'answer', and assigns this value to the result variable.arrow_forwardNow do it the fixed sliding window of building a tri-gram dictionary method. You can start after 256 for the dictionary index. (a) Use window size 3 for the text: “pugonthepugonrug” (b) Think about how many of these tri-grams are used (or not used). Can you think of a way to reduce the number of tri-grams that only occur once?arrow_forward

- This assignment requires you to create a dictionary by reading the text file. Text file name: LightningP Text file contents: Stamkos3538Maroon2933Point5055Kucherov5565Killorn3340 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. 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. Printing the stats for each player is the most challenging part of this program. The required output should be the same well-formatted table as below: PLAYER COLUMN: 10 characters wide and left-aligned. GOALS COLUMN: 6 characters wide and centered. ASSISTS COLUMN: 8 characters wide and centered. TOTAL COLUMN: 6 characters wide and centered. Example output:arrow_forwardSuppose a dictionary named inventory exists. What does the following statement do?del inventory[654]arrow_forwardImplement the following: Given: user_001 = {'username': 'jSmith001', 'first': 'John', 'last': 'Smith'} 1) Remove the key/value pair 'last':'Smith' from the dictionary user_001. 2) Access the values in the dictionary user_001 to print the following. Make sure to precisely match the output format below. Write your code in the ANSWER area provided below (must include comments if using code is not covered in the course).

- 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 callarrow_forwardCreates and returns a mutable dictionary, initially giving it enough allocated memory to hold a given number ofentries.arrow_forwardGiven a dictionary where you have names of students as keys and their 3 exam grades as values, write a segment of code that calculates the average of every student and puts it in a list named averages. Then calculates the average of the class by averaging the results in the list averages.
