Use PYTHON that uses a dictionary to code simple contact tracing. In the dictionary, you SHOULD use the get() method. There are three key person - key person 1,2,3 and the program should print the close contact of the three key persons. However, the program prints 'No Data' if the person has no record for a contact. NOTE: Input should always be 10 positive integers. Program Input: Program Output: 888 222 333 333 555 888 444 555 333 888 #key person 1, person ID # close contact of person 888 # close contact of person 888 #key person. 2, person ID # close contact of person 333 # close contact of person 333 # key person 3, person ID # close contact of person 444 # close contact of person 444 #lookup close contacts of person 888 contacts of 888 [222, 333] contacts of 222 No Data contacts of 333 [555, 888]

Write a python program that will make a dictionary from the given list of Student IDs based on the department and admitted year. ID explanation: First 2 digits: Year 4th and 5th digit: Department 01 = CSE, 41=CS, 21=EEE For example, ID: 21121347, in this ID, the first 2 digits are 21. So the year is 2021. The 4th and 5th digit are 21. So the department in EEE. Given List [Your code should work for all types of similar IDs if the given List is changed.]: IDs = ['20201199','21121347','19101052','19301121','20221369','21241199','19241187','20141007','20101035', '21121875', '19141534', '20341552', '20121135', '21341001'] Sample Output (You have to print the resultant dictionary only) { 'CSE':{ '2020': ['20201199', '20101035'], '2019': ['19101052', '19301121'] }, 'EEE':{ '2021': ['21121347', '21121875'], '2020': ['20221369', '20121135'] }, 'CS':{…
Write 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 program should then 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 a count of the number of correct and incorrect responses.
My question is to modify binary search to only display the result with book title with its ID number. Here is the code to modify: def search_books(self, book_title): # Remove leading and trailing white spaces and convert to lowercase book_title = book_title.strip().lower() # Extract book titles and IDs from self.books_dict book_titles = [value["books_title"].strip().lower() for key, value in self.books_dict.items()] #book_ids = list(self.books_dict.keys()) # Sort the book titles and IDs together book_titles, book_ids = zip(*sorted(zip(book_titles, book_ids))) #zip takes iterable or containers and return a single iterator # Perform binary search for the book title low = 0 high = len(book_titles) - 1 while low <= high: mid = (low + high) // 2 bt = book_titles[mid].replace('"', '') if bt == book_title: print(f"Book '{book_title}'…
Let's assume that a player plays a multi-agent game where, every gun has a type: "Sidearms" or "Rifles" or "Sniper Rifles". Here, in every dictionary inside the tuple, the key is the gun name, the first index of the dictionary value is the gun type and the second index of the dictionary value is the kills done by that gun in a certain match. Now, write a Python program that will generate a dictionary from the given tuple of dictionaries: ================================================ Given Tuple 1: ({"Ghost" : ["Sidearms", 3]}, {"Vandal" : ["Rifles", 15]}, {"Sheriff" : ["Sidearms", 5]}, {"Operator": ["Sniper Rifles", 7]}, {"Phantom" : ["Rifles", 10]}) Sample Output 1: {"Sidearms" : ["Ghost","Sheriff", 8], "Rifles" : ["Vandal", "Phantom", 25], "Sniper Rifles" : ["Operator", 7]} Explanation1: Here, in the expected dictionary the keys will be the type of the guns and the values for an individual key will have the gun names and the sum of the kills by those guns in a…

Can you answer with the Python software language ? Write a function that takes two arguments: stock and ingr (short for ingredients) and returns the missing ingredients in stock. stock is a dictionary containing (key,value) pairs in the form of ("potato", 5). The key is the name of an ingredient, and the vlaue is its existing amount. ingr is a list of tuples, where each tuple represents the required amount of an ingredient. For example, ("cheese", 3) means we need 3 units of cheese for this recipe. Your function checks whether we have enough of each item in the stock. If an item is missing or not enough then your function returns the missing amount within a list of all such items. If all items are in stock, then you return an empty list. For example: stock = {"salt":100, "sugar":100, "flour":50, "apple":3, "cream":10} ingr = [("sugar",50), ("flour", 120), ("apple",5)] checkStock(stock, ingr) should return [("flour",70), ("apple",2)] which means we need 70 more units of flour and 2…
