- 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…Exercise: Least Dictionary Value Description In this exercise you will find the value in a dictionary with the least value. Least means that the value is less than or equal to all other values in the dictionary. Remember that the 2 Assistant Object inspectorvoid 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);
- Dictionary 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} {} {}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':…PHP Write a reduce function Write a function reduce($arr, $func) that takes an array and a function as a parameter. The reduce function should apply the parameter function to each element of the array in succession to produce a single result. Note: the current result should always be the first parameter to the function and the next element of the array should always be the second parameter. You may not use the PHP function array_reduce in your solution. For example, the result of the following should be 10. function myMax($current, $new) { return $current < $new ? $new : $current; } $arr = array(10, 5, 3, 5, 1, 2, 5, 7, 4); print("Max: " . reduce($arr, 'myMax') .
- Find 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",…3. lookup_friends_heights This function takes a friends database (a list of dictionaries, like the previous functions) and a list of friends names, and it returns a list of heights for the specified friends. If a given friend's name is not present in the friends database, we put a None in the corresponding slot. We assume that there will be at most one friend with a given name in the list. You may want to use nested for-loops for this function. Sample calls should look like this. >>> lookup_friends_heights([{"name":"todd","height":170},{"name": "sarah", "height":165},{"name":"dweezil", "height":175}], ["dweezil", "sarah"]) [175, 165] >>> lookup_friends_heights([{"name": "todd","height":170},{"name": "sarah","height":165},{"name": "dweezil", "height":175}], %3D ["sarah", "elíza", "dweezil"]) [165, None, 175]C 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.
- 3. lookup_friends_heights This function takes a friends database (a list of dictionaries, like the previous functions) and a list of friends names, and it returns a list of heights for the specified friends. If a given friend's name is not present in the friends database, we put a None in the corresponding slot. We assume that there will be at most one friend with a given name in the list. You may want to use nested for-loops for this function. Sample calls should look like this. >>> lookup_friends_heights([{"name":"todd","height":170},{"name": "sarah","height":165},{"name":"dweezil","height":175}], ["dweezil", "sarah"]) [175, 165] >>> lookup_friends_heights([{"name": "todd","height":170},{"name": "sarah","height":165},{"name": "dweezil", "height":175}], ["sarah", "elíza", "dweezil"]) [165, None, 175]3. lookup_friends_heights This function takes a friends database (a list of dictionaries, like the previous functions) and a list of friends names, and it returns a list of heights for the specified friends.

Define a Friend class , where each Friend object…python exercise: Write a Python function called get_top_students that takes the list of dictionaries as input and returns a dictionary containing the name and GPA of the top two students in the list.
