- Code the following directions in python. 1.Assume the variable dct references a dictionary. Write an if statement that determines whether the key 'Jim' exists in the dictionary. If so, delete 'Jim' and its associated value. 2.Write code to create a set with the following integers as members: 10, 20, 30, and 40. 3.Assume each of the variables set1 and set2 references a set. Write code that creates another set containing all the elements of set1 and set2, and assigns the resulting set to the variable set3.Implement the following: Given: user_001 = {'username': 'jSmith001', 'first': 'John', 'last': 'Smith'} 1) Remove the key/value pair 'last':'Smith' from the dictionary user_001. 2) Access the values in the dictionary user_001 to print the following. Make sure to precisely match the output format below. Write your code in the ANSWER area provided below (must include comments if using code is not covered in the course). Example Output Hi John, your new login is jSmith001.Code the following directions in python: 1.Write a statement that creates a dictionary containing the following key-value pairs: 'a' : 1 'b' : 2 'c' : 3 2.Write a statement that creates an empty dictionary. 3.Assume the variable dct references a dictionary. Write an if statement that determines whether the key 'James' exists in the dictionary. If so, display the value that is associated with that key. If the key is not in the dictionary, display a message indicating so.
- 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);Assume the variable dct references a dictionary. Write an if statement that determines whetherthe key 'Jim' exists in the dictionary. If so, delete 'Jim' and its associated value.Overview This is a review assignment where you will use multiple tools you have picked up so far throughout the course. If you're confused about how to do something make sure you look back at earlier assignments. In this program you will start by declaring an empty dictionary named population_dict. Then you will use a while-loop to prompt a user for a series of cities and their populations, storing the input in population_dict). After this you will prompt the user to decide what is the maximum population for a city to be considers a small down. Finally, you will open a file called populationdata.txt where you will write the results. Expected Output Example of standard out (the console): What is next city? (enter q to quit) Long Beach What is the population of Long Beach? 362000 What is next city? (enter q to quit) Los Angeles What is the population of Los Angeles? 382000000 What is next city? (enter q to quit) San Diego What is the population of San Diego? 136000000 What is next city?…
- Assume that d refers to a dictionary. Write a statement in Python that retrieves from the dictionary the value that is associated with the key 'answer', and assigns this value to the result variable.Overview This program will have you use a loop to prompt a user for three games and their systems and then store them in a dictionary called games_dict). Then it will ask the user for the worst game, delete that game, and print out the contents of the revised games_dict. Expected Output Example 1 What is a great game? Mario What system can I play that on? Nintendo What is a great game? Sonic I play that on? Sega What system can What is a great game? Spyro What system can I play that on? layStation That's too many, let's get rid of one What game should we remove? Sonic The new dictionary is: You can play Mario on Nintendo You can play Spyro on PlayStation Specifications • You should submit a single file called M4A3.py • It should follow the submission standards outlined here: Submission Standards • Your program should start by defining an empty dictionary called games_dict • It should populate games_dict using a for-loop • It should print out games_dict using a for-loop.

(Note: the order of the display of entries in a dictionary are not in a specific order.)Write code that prints out the keys that have a value less than 3 in the following dictionary: d= {'a':5, 'is':3, 'this':2, 'program':1}Task 7 Suppose you are given two dictionaries. Now create a new dictionary "marks", merging the two dictionaries, so that the original two dictionaries remain unchanged. Note: You can use dictionary functions. Given: {'Harry':15, 'Draco':8, 'Nevil":19} {'Ginie':18, 'Luna': 14} Output: {'Harry': 15, 'Draco': 8, 'Nevil": 19, 'Ginie": 18, 'Luna': 14}
