- Word FrequencyWrite a python program that reads the contents of a text file. The program should create a dictio-nary inwhich the keys are the individual words found in the file and the values are the number of timeseach word appears. For example, if the word “the” appears 128 times, the dictionary wouldcontain an element with 'the' as the key and 128 as the value. The program should eitherdisplay the frequency of each word or create a second file containing a list of each word and itsfrequency.arrow_forwardPython Programming Assignment: Create a dictionary that takes a basketball team's information (that includes team's name and points) as parameter, creates a teams_dict and returns it. Also, create a parameter for write_file parameter that opens current results text file in write mode and writes the dictionary information to file as per format and closes the file.arrow_forwardIn Python Please check the pictures first. Write a program that keeps names and email addresses in a dictionary as key-value pairs. The program should display a menu that lets the user look up a person’s email address, add a new name and email address, change an existing email address, and delete an existing name and email address. The program should save the data stored in a dictionary to a file when the user exits the program. Each time the program starts, it should retrieve the data from the file and store it in a dictionary. You Must create and use at least 5 meaningful functions. A function to display a menu A function to look up a person’s email address A function to add a new name and email address A function to change an email address A function to delete a name and email address. Check the Your program should check user input; for example, if the user wants to delete a name that does not exist in the dictionary, you should print something like: the name is not in the…arrow_forward
- Data 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_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_forward1. Course informationWrite a program that creates a dictionary containing course numbers and the room numbers ofthe rooms where the courses meet. The dictionary should have the following key-value pairs:Course Number (key) Room Number (value)CS101 3004CS102 4501CS103 6755NT110 1244CM241 1411The program should also create a dictionary containing course numbers and the names of theinstructors that teach each course. The dictionary should have the following key-value pairs:Course Number (key) Instructor (value)CS101 HaynesCS102 AlvaradoCS103 RichNT110 BurkeCM241 LeeThe program should also create a dictionary containing course numbers and the meeting timesof each course. The dictionary should have the following key-value pairs:Course Number (key) Meeting Time (value)CS101 8:00 a.m.CS102 9:00 a.m.CS103 10:00 a.m.NT110 11:00 a.m.CM241 1:00 p.m.The program should let the user enter a course number, then it should display the course’s roomnumber, instructor, and meeting time.arrow_forward
- This 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_forwardCode in python. Assume the variable dct references a dictionary. Write code that pickles the dictionary and saves it to a file named mydata.dat.arrow_forwardURGENT: Python Expense Management: This system will add, deduct, update, sort, and export expenses to a file. The program will initially load a collection of expenses from a .txt file and store them in a dictionary. All of the necessary functions and unit testing are provided below in expenses.py, expenses_test.py, and expenses.txt: expnses.py: def import_expenses(file): '''Reads data from a given file and stores the expenses in a dictionary, where the expense type is the key and the total expense amount for that expense is the value. The same expense type may appear multiple times in the file. Ignores expenses with missing or invalid amounts.''' # create empty dict expenses = {} #TODO insert your code return expenses def get_expense(expenses, expense_type): '''Returns the value for the given expense type in the given expenses dictionary.

Write an if statement that determines whether the key ‘Jim’ exists in the dictionary. If so, delete ‘Jim’ and its associated value. (write as a function) 2.

Write a program that reads the contents of a text file. The program should create a dictio-nary in which the keys are the individual words found in the file and the values are the number of times each word appears. For example, if the word “the” appears 128 times, the dictionary would contain an element with 'the' as the key and 128 as the value. The program should either display the frequency of each word or create a second file containing a list of each word and its frequency.arrow_forward
