The text edited by a line editor is represented by a doubly linked list of nodes, each of which contains an 80 column line of text (type LineType). There is one external pointer (type LineType*) to this list, which points to the "current" line in the text being edited. The list has a header node, which contains the string "- - - Top of File - - -" and a trailer node, which contains the string "- - - Bottom of File - - -". a. Draw a sketch of this data structure. b. write the type declaration to support this data structure. c. write the class constructor, which sets up the header and trailer nodes

In Python Write a program that reads movie data from a CSV (comma separated values) file and output the data in a formatted table. The program first reads the name of the CSV file from the user. The program then reads the CSV file and outputs the contents according to the following requirements: Each row contains the title, rating, and all showtimes of a unique movie. A space is placed before and after each vertical separator ('|') in each row. Column 1 displays the movie titles and is left justified with a minimum of 44 characters. If the movie title has more than 44 characters, output the first 44 characters only. Column 2 displays the movie ratings and is right justified with a minimum of 5 characters. Column 3 displays all the showtimes of the same movie, separated by a space. Each row of the CSV file contains the showtime, title, and rating of a movie. Assume data of the same movie are grouped in consecutive rows. Ex: If the input of the program is: movies.csv and the contents…

in phython language Create a module file named mystatistics.py. This module should define two functions: mean() and median(). Both functions takes a list as a parameter. mean() function calculates the average of all elements in the parameter list and returns it. median() function sorts the list first. If the number of elements in the list is odd, it returns the middle element. If it is even then it averages the two middle elements and then returns the value. Python has its own statistics library which has mean and median functions. Use them to test your functions and place a testing code in your module.

Filename: runlength_decoder.py Starter code for data: hw4data.py Download hw4data.py Download hw4data.pyYou must provide a function named decode() that takes a list of RLE-encoded values as its single parameter, and returns a list containing the decoded values with the “runs” expanded. If we were to use Python annotations, the function signature would look similar to this:def decode(data : list) -> list: Run-length encoding (RLE) is a simple, “lossless” compression scheme in which “runs” of data. The same value in consecutive data elements are stored as a single occurrence of the data value, and a count of occurrences for the run. For example, using Python lists, the initial list: [‘P’,‘P’,‘P’,‘P’,‘P’,‘Y’,‘Y’,‘Y’,‘P’,‘G’,‘G’] would be encoded as: ['P', 5, 'Y', 3, ‘P’, 1, ‘G’, 2] So, instead of using 11 “units” of space (if we consider the space for a character/int 1 unit), we only use 8 “units”. In this small example, we don’t achieve much of a savings (and indeed the…
