- void 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);Python Write a function print_dict to print all the key-values in a dictionary, for example: >>> d2 {'a': 'one', 'b': 'two', 'c': 'Three'} >>> print_dict(d2) a:one b:two c:Threedef most_total(bdm): '''(dict of {str: dict of {int: list of str}}) -> str bdm is a birthday month dictionary with at least one key. Return the name of the month with the most total days on which someone has a birthday. If there is a tie, return any month with that maximum. >>> d = {"Jan": {1: ["Steve"], 5: ["Bob"], 31: ["Ron"]}, "Aug": {1: ["Jim", "Tim"], 24: ["Sadia", "Tony"]}} >>> most_total(d) 'Aug' '''
- Homework Assignment-1Topics: Functions, Dictionary, ImportProblem description: Write a python application to simulate an online clothing system. Thepurpose of this assignment is to gain experience in Python dictionary structure, create basicPython functions and import a module.Design solution: The template file contains a list of clothes item sold, each item in the listcontains the item id, name of the item and the prices. The program will generate an items_dictwhere each key is the item id of the cloth and the values will be a list of item name and priceinformation. A customer will be presented with a main menu with 4 different options: displayall items, add an item to cart, checkout and exit the program. A customer can buy an item byentering the ID of the item. This program implements a dictionary called cart, where each key isthe item id and the values are the list of name, price and quantity that user chooses topurchase. The program keeps repeating by displaying the main menu to…File Encryption and DecryptionWrite a program that uses a dictionary to assign “codes” to each letter of the alphabet. Forexample:codes = { ‘A’ : ‘%’, ‘a’ : ‘9’, ‘B’ : ‘@’, ‘b’ : ‘#’, etc . . .}Using this example, the letter A would be assigned the symbol %, the letter a would beassigned the number 9, the letter B would be assigned the symbol @, and so forth.The program should open a specified text file, read its contents, then use the dictionaryto write an encrypted version of the file’s contents to a second file. Each character in thesecond file should contain the code for the corresponding character in the first file.Write a second program that opens an encrypted file and displays its decrypted contentson the screen. in phytonDictionary Swap Write a function called dictionary_swap that takes a dictionary as a parameter. It does not modify the original dictionary, but it creates and returns a new one. Keys from the original dictionary become values in the new one, and values become keys. For example, given the inputs below, your program should return the corresponding values. Input to the Function Returns {'one':1, 'two': 2, 'three':3} {1:'one', 2:'two', 3:'three'} {-1:-10, -2:-20, -3:-30} {-10:-1, -20:-2, -30:-3} {} {}
- Write a function, young_john(people), that returns True if the dictionary people contains the key "John" with a value of 19. It should return False otherwise. like this def young_john(people):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.txtFind Country Function Name: findCountry() Parameters: capitalList ( list ) Returns: Dictionary mapping each capital to its country( dict ) Description: Given a list of countries' capital cities, write a function that returns a dictionary that maps a capital to its country's name. Note: Assume that all capital cities provided are valid. example test cases: >>> findCountry(('tokyo', 'delhi', 'stockholm']) {'tokyo': 'Japan', 'delhi": 'India', 'stockholm': 'Sweden'} >>> findCountry(l'paris', 'canberra', 'copenhagen']) {'paris': 'France', 'canberra': 'Australia', 'copenhagen': 'Denmark'} For this assignment, use the REST countries API (https://restcountries.com/#api-endpoints-v2). For all of your requests, make sure you to use version 2 of the REST countries API (V2), not version 3 (V3.1). If you make a request with the URL: https://restcountries.com/v2/alpha/usa, you will receive the following response: { "name": "United States of America", "topLevelDomain": [".us"], "alpha2Code": "US",…
- In C++ data structure Please write program per instructions. Thank you A set is a collection of distinct elements of the same type. Design the class unorderedSetType, derived from the unorderedArrayListType, to manipulate sets. Note that you need to redefine only the f unctions insertAt, insertEnd, and replaceAt. If the item to be inserted is already in the list, the functions insertAt and insertEnd output an appropriate message. Similarly, if the item to be replaced is already in the list, the function replaceAt outputs and appropriate message. Also, write a program to test your class: then Redo the program using templatesC language. Function write the arraylist_sort function This generic function sorts an array list using the given compare function. l An array list compare Pointer to the function which compares two elements If you cannot write down a generic function which works for all types, write down a function which sorts resturants. If you cannot use function pointers, you can write down multiple functions which sort using different criteria.Estimated Completion Time: 2 minutes You are now working for Prof. Midas on a research project. You are given this piece of code to review which is intended to be a better and faster implementation of a function that checks whether a given key is in a dictionary (i.e., key lookup). You have to present your findings to Prof. Midas. Select all the findings which you will NOT present (i.e., select all answers which are FALSE). def key_in_dict(d, k): for item in d: if k == item: return True return False This code would always be slower than the builtin key lookup Python provides. O A key lookup in a dictionary in Python is generally faster than determining whether a value is in a list. O This code is way faster and will be included in the next version of Python (version 4.1). The code is incorrect from a functional perspective, the True and False should be switched. This code could be replaced with one line: return k in d O The code is correct and would always perform faster than the…
