Concept explainers

Stack operations

A stack is a linear data structure that follows certain order to perform the operation; the order will be LIFO (Last In First Out) data structure. In the stack data structure elements/items are removed and added only from the top. The topmost stack item/element is pointed by the top pointer and the element which is added to the stack first will get deleted at the last.

Question

Define a function read_data that accepts a single argument corresponding to
the filename, and returns a list of lists. You can find an example file to work
within the Brightspace and the startercode section of the Vocareum Each line in
the data file follows this format: "[Name], num1, num2, num3 . . . ." Ben,
-1, 2.3, 4.1, 5.25, -4, 0.2, 0.55, 1.1 Mary,2.1, 1.4, 1.2, 1.5, 1.0, 2, 3.1 Giulia,
1.8, -2.2, -1.6,3 The function must return a list of lists where each sublist
represents one line from the file. All the numbers must be converted to float
datatype in the returned value Sample output: > > print(read_data('sample_
data.txt')) [['Ben', - 1.0, 2.3, 4.1, 5.25, -4.0, 0.2, 0.55, 1.1], ['Mary
', 2.1, 1.4, -1.2, 1.5, 1.0, 2.0, 3.1], ['Giulia', 1.8, -2.2, 1.6, 3.0]]

Write a Python program that calculates the average 5 quiz scores from a file with student ID and scores. Your program must have 2 functions; the main and calculateAvg- The main function reads data from an input file, which has the format shown below. Each line in the file starts with the Student ID followed by 5 values representing the scores attained by the Student in 5 quizzes. For each Student, the calculateAvg function receives a list containing the 5 values and returns another list containing all the values in the original list plus the average score of the quizzes for each student. This information will be written in an output file as shown below. Also, you must include the class average at the end. Which includes all the students in the list. Note: You program must be general and works for any number of Students. All reading and writing must be done in the main function.

Write a function called find_duplicates which accepts one list as a parameter. This function needs to sort through the list passed to it and find values that are duplicated in the list. The duplicated values should be compiled into another list which the function will return. No matter how many times a word is duplicated, it should only be added once to the duplicates list. NB: Only write the function. Do not call it. For example: Test Result random_words = ("remember","snakes","nappy","rough","dusty","judicious","brainy","shop","light","straw","quickest", "adventurous","yielding","grandiose","replace","fat","wipe","happy","brainy","shop","light","straw", "quickest","adventurous","yielding","grandiose","motion","gaudy","precede","medical","park","flowers", "noiseless","blade","hanging","whistle","event","slip") print(find_duplicates(sorted(random_words))) ['adventurous', 'brainy', 'grandiose', 'light', 'quickest', 'shop', 'straw', 'yielding']…
please code in pythonRead in and return a list of review dates. The function should ask the user to enter some review dates This should be entered in the format mm/dd/yyyy (same as that in the file) where dd is two-digit day, mm is two digit month and yyyy is a four digit year e.g. 01/22/2020 The function should return a list containing the specified review dates. :return: a list of review datesYou can take any review date as sample example
The mapped list pattern Our second pattern is the mapped list pattern, described in video 4 3 mapped list pattern. Often we need to write a function that takes a list as a parameter and returns a new list in which each item in the original list is "mapped" to a new item in the result list. For example, the following function takes a list of numbers as a parameter and returns a list of all the numbers squared, e.g. squares ( [1, 3, 7]) returns [1, 9, 49]. def squares (nums): "Returns the squares of the given numbers""" result = [] for num in nums: result.append (num * num) return result Although this is just a special case of the accumulator pattern, it is so common that we give it its own name: the mapped list pattern. Consider the following function: def squares(nums): ""Returns the squares of the given numbers""" result = [] for num in nums: result.append (num * num) return result If the main program calls print(squares ( [5, -3, 2, 7]) what is the state table for the function…

PYTHON!!! Write a function that will filter course grades that are stored in a list, creating and returning a new list. Your implementation must have the following rules: - The function must accept two (and only two) parameters: The first is: the maximum integer value for any grade to remain in the list (any value above the maximum will be filtered and removed from the list). The second is: the list of grades (you can assume the list contains only integer values) - The function must return a new list and not modify the existing list. - The function must use a list comprehension to filter the existing list and create the new list that is returned. - DO NOT USE THE: built-in-"filter" function.
The next part of the program reads the file one line at a time and adds the scores, as a floating point numbers, to the list scores. scores = [] # empty list of scores for line in infile: line = line.strip() print (scores) # get score #convert to float # add to list of scores In the space below, complete the program fragment so that it prints the list of floating point scores as follows: [98.5, 97.4, 99.1, 97.2]
OCaml Code: Please read the attached instructions carefully and show the correct code with the screenshot of the output. I really need help with this assignment.
code in python The function print_reverse takes one parameter, L, which is a list. The function then prints the items in the list in reverse order, one item per line, WITHOUT changing the value of L. Write the function definition. Note 1: This function does NOT get anything from standard input. Note 2: This function DOES, however, print to standard output. Note 3: You should NOT return anything from this function (let it return None by default). Hint: Some ideas for iterating over a list in reverse order are given here. For example: Test Result L = ['apple', 'banana', 'cherry'] Lcopy = L[:] return_value = print_reverse(L) if return_value != None or L != Lcopy: print("Error") cherry banana apple L = ['happy'] Lcopy = L[:] return_value = print_reverse(L) if return_value != None or L != Lcopy: print("Error") happy L = [] Lcopy = L[:] return_value = print_reverse(L) if return_value != None or L != Lcopy: print("Error")
