Capital Quiz
use pythonThe Capital Quiz ProblemWrite a program that creates a dictionary containing the U.S. states as keys, and their capitals asvalues. (Use the Internet to get a list of the states and their capitals.) The program should thenrandomly quiz the user by displaying the name of a state and asking the user to enter that state’s574capital. The program should keep a count of the number of correct and incorrect responses. (Asan alternative to the U.S. states, the program can use the names of countries and their capitals
Lists: Create a list of student names. These are strings representing the names of
students in your class (e.g., ["John", "Mary", "Peter", "Sam"]).
2. Tuples: For each student, create a tuple that stores their grades in different subjects. The
subjects are Mathematics, English, and Science (e.g., (85, 90, 88)).
3. Dictionaries: Now, create a dictionary where the keys are the names of the students
(from your list), and the values are the tuples storing their grades. This way, you can
easily look up a student's grades in different subjects.

- Word IndexWrite a python program that reads the contents of a text file. The program should create a dictionary inwhich the key-value pairs are described as follows:Key. The keys are the individual words found in the file.576Values. Each value is a list that contains the line numbers in the file where the word (thekey) is found.For example, suppose the word “robot” is found in lines 7, 18, 94, and 138. The dictionarywould contain an element in which the key was the string “robot”, and the value was a listcontaining the numbers 7, 18, 94, and 138.Once the dictionary is built, the program should create another text file, known as a word index,listing the contents of the dictionary. The word index file should contain an alphabetical listingof the words that are stored as keys in the dictionary, along with the line numbers where thewords appear in the original file. Figure 9-1 shows an example of an original text file(Kennedy.txt) and its index file (index.txtarrow_forwardThis is in Python Capital Quiz. This is a problem in which you use dictionaries. Write a program that creates a dictionary containing twenty (only twenty) States of the United States and their State Capitals. The States of the United States should be the keys. The program also should randomly quiz the user by displaying the name of a State and asking the user to enter that state's capital. The program should keep of a count of the number of correct responses. The program should ask the user how many times the user wants to play. If the user says 6, the quiz should run six times and the final output should say, you played this game six times and you got the answers correct four times (if the user got four answers correct).arrow_forwardData structures dict_from_string(dict_str:str)->dict This function will be given a single parameter, a string representing a dictionary. Your job is to convert the string into an actual dictionary and return the dictionary. Make sure all key-value pairs in the string exist in the newly created dictionary. The string will contain only numbers or single letters as key values pairs. Make sure all letters are kept as strings and all numbers are converted to integers in the newly created dictionary. Example: String Input: '{9: 'V', 'G': 0, 'M': 9, 'u': 3, 2: 'o', 8: 'u', 'q': 9, 'D': 1}' Expected: {9: 'V', 'G': 0, 'M': 9, 'u': 3, 2: 'o', 8: 'u', 'q': 9, 'D': 1} String Input: '{10: 'D', 1: 'Z', 5: 'a'}' Expected: {10: 'D', 1: 'Z', 5: 'a'} String Input: '{'M': 2, 'V': 0, 3: 'x', 6: 'J', 5: 'J', 7: 'T', 8: 'P', 4: 'q', 1: 'h'}' Expected: {'M': 2, 'V': 0, 3: 'x', 6: 'J', 5: 'J', 7: 'T', 8: 'P', 4: 'q', 1: 'h'} String Input: '{3: 'D', 10: 'T', 7: 'm', 'u': 9, 't': 5, 6: 'Z', 'H': 10, 'B':…arrow_forward

The input file contains an unsorted list of number of seasons followed by the corresponding TV show. Your program should put the contents of the input file into a dictionary where the number of seasons are the keys, and a list of TV shows are the values (since multiple shows could have the same number of seasons). Sort the dictionary by key (least to greatest) and output the results to a file named output_keys.txt, separating multiple TV shows associated with the same key with a semicolon (;). Next, sort the dictionary by values (alphabetical order), and output the results to a file named output_titles.txt.

- 3. form_letter This function takes a list of dictionaries, where each dictionary has an entry of key "name" and entry of key "date". It returns a list of strings, where each output string has replaced the name and the date into the following template. Use the format method on strings -- see Lecture 8! The template should be exactly like this -- just copy-paste this into your code. TEMPLATE = """Dear {name},Your appointment is at {time}.Thanks very much.-- bimmy""" It can be either local to your function, or global in your Python file. Your choice! Sample calls should look like this. >>> form_letter([{"name":"Alex", "time":"three o'clock"},{"name":"Laura", "time":"the stroke of midnight"}])["Dear Alex,\nYour appointment is at three o'clock.\nThanks very much.\n-- bimmy", 'Dear Laura,\nYour appointment is at the stroke of midnight.\nThanks very much.\n-- bimmy']arrow_forwardThis should use a dictionary for the replacement words. Write a program that replaces words in a sentence. The input begins with word replacement pairs (original and replacement). The next line of input is the sentence where any word on the original list is replaced. Ex: If the input is: automobile car manufacturer maker children kids The automobile manufacturer recommends car seats for children if the automobile doesn't already have one. the output is: The car maker recommends car seats for kids if the car doesn't already have one. You can assume the original words are unique. please make it simple im begginer in pythonarrow_forwardvoid dict_clear (dict_t* dict); This function clears the dictionary dict, destroying each pair key/value, but does not destroy dict itself (remember that dict was allocated using dict_create, so it will need to be freed at some point, but this is not this function’s job.) This is now the function that frees (destroys) a dictionary: void dict_destroy (dict_t* dict); This operates just as dict_clear, but in addition should free the memory that was allocated during dict_create. After a call to this function, if any other library function receives the pointer dict, the behavior is undefined (most likely, it will crash). This simple function returns the current size of the dictionary: size_t dict_size (const dict_t* dict);arrow_forward
