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.
In cell C18 type a VLOOKUP function to find the corresponding letter grade (from column D) for the name in A18. The table array parameter is the same as in B18. Type FALSE for the range lookup parameter. Copy the formula in C18 to C19:C22Notice this formula works correctly for all cells. Range lookup of FALSE means do an exact match on the lookup value whether or not the table array is sorted by its first column. In cell E11, type an IF function that compares the score in B11 with the minimum score to pass in A5. If the comparison value is true, display Pass. Otherwise, display Fail. Copy the formula in E11 to E12:E15. Did you use appropriate absolute and relative references so the formula copied properly? In cell F11, type an IF function that compares the grade in D11 with the letter F (type F). If these two are not equal, display Pass. Otherwise, display Fail. Copy the formula in F11 to F12:F15

Assuming food is a Dictionary, what does the following statement do? food[101] = "Cheesburger"; Question 63 options: a) After the statement executes, the Dictionary will have an element with the key 101 and the value “Cheeseburger.” b) After the statement executes, the Dictionary will have an element with the key “Cheeseburger” and the value 101 c) After the statement executes, the element at position 101 will have the key “Cheeseburger.” d) After the statement executes, the Dictionary will have 101 elements, each with the key “Cheeseburger.”
PYTHON QUESTION This assignment requires you to create a dictionary by reading the text file created for the Chapter 6 assignment. The dictionary should have player names for the keys. The value for each key must be a two-element list holding the player's goals and assists, respectively. See page 472! Start with an empty dictionary. Then, use a loop to cycle through the text file and add key-value pairs to the dictionary. Close the text file and process the dictionary to print the stats and determine the top scorer as before. In fact, much of the code used in program6_2.py can be copied and used for this program. Printing the stats for each player is the most challenging part of this program. To master this, refer to the examples in the zip file that can be downloaded from the "Dictionary values can be lists" link in the "Learn Here" part of this module. NOTE: you do not need to submit the text file. Submit just this program. The required output should be the same well-formatted table…
Which of the following statements regarding linked lists and arrays is correct? Group of answer choices: a. A dynamically resizable array makes insertions at the beginning of an array very efficient. b. Using a doubly linked list is more efficient than an array when accessing the ith element of a structure. c. A dynamically resizable array is another name for a linked list. d. Any type of list tends to be better than an array when there are a set number of maximum items known beforehand. e. If many deletions at any place in the structure were common, a linked list implementation would likely be preferable to an array
PART A. We will start by finding the largest value. Initially, we assume that the first element in the list is the largest element and create a variable maxValue that is initialized to the first element in the array. We then compare the element that maxValue is storing with every element in the list. Whenever we find an element in the array larger than the element that maxValue is storing, we update maxValue so that it stores the value of the newer larger element. Algorithm ArrayLargestElement Declare and initialize maxValue to the first element in the array. Use a FOR loop to traverse the array. // You already checked the first element, so you should start the loop at the second element. If the element at this index is larger than maxValue Update maxValue Output maxValue. Write a program MyArray_ABC that declares an array containing the following elements: 45, 38, 27, 46, 81, 72, 56, 61, 20, 48, 76, 91, 57, 35, and 78, and outputs the largest value. Additionally,…
Assume the following list exists: names = ['Chris', 'Katie', 'Joanne', 'Kurt'] Write a statement that uses a dictionary comprehension to create a dictionary named X in which each element contains the length of a name from the list as the key, and the corresponding name's initial character as its value.
