Use Python 3 for this question. Do the sentiment analysis based on a text file which contains numerous tweets in its raw text format. All tweets collected in this file contains a key word specified by the instructor. The key word being used is “Trump”. You can use the raw tweets file provided by the following link: tinyurl.com/46ntt3a5. You will need to convert this to a .txt file for this assignment. Your raw tweets file size at least needs to be 350K. After you have the raw tweets file ready, you need to perform the following tasks in a Jupyter notebook file. First you need to clean up the tweet file content to the best you can. For each word that is not a “stop word” (and, the, a, is, as, …), assign a value +1 for positive sentiment or a value -1 for negative sentiment. A list of “positive” words will be provided to you. You can easily find a list of “stop words”, and a list of “negative” words online. For the words that is not in positive/negative/stop words, count as ‘others’.…
File names: color_square.py, chessboard.py, test_squares.py Positions on a chess board are identified by a letter and a number. The letter identifies the column; the number identifies the row. See the image below. You will provide the functions that allow us to determine: if a chessboard square is either black or white, given its coordinates. If the row/column is valid or not for the standard chessboard For example, if we pass in “d” for the column and 4 for the row, your function that determines color should return the string: “BLACK”. If we pass in "k" for the column to your function that validates columns, that function should return the boolean False. Requirements: Your function for validating the column should be able to accept upper or lowercase strings as parameters. Your functions for validating the row should be able to accept integers or strings as parameters. Your function that determines black-or-white may assume that the input has been validated prior to us calling…
Assistance is needed for Python please The objective is to create a code in Python that can extract the columns highlighted in blue (Column T and AB3) and output them to a .txt file. The code should be able to generate the text file with the columns that are highlighted in blue and store them on a separate folder. Below shows how the Test.xlsm file looks like as well as how the text file should look like when the code extracts and outputs it. Google drive to access Test.xlsm file: https://drive.google.com/drive/folders/16utzb5_h7yMCN8_13E_JqasfcpykZOYr?usp=sharing What my code outputs is shown in the picture (O1.png) What I would like for my code to output is the columns next to each other (Right Example.png) The current code is able to output Columns T and AB3 but I am not able to output them next to each other as shown above. We would also like for the code to be capable of storing the text file to a separate folder. Below is the code I have been working on. #package to read xlsm…
Answer All the questions. Make sure your answers are short and precise. You can use (Q1.txt or Ed) files to check your answers for Q1. 1. The phone numbers collected from questionnaire is a mess. Design a regular expression to filter out those numbers that are stored in the standard format "+00-0-0000-0000" from the file called "Q1.txt" and redirect the results to the "cleaned.txt". +61392144979 +61 3 9214 4778 +61-3-9214-4980 +66(2)51574430 +61-3-9285-7706 Note: Only +61-3-9214-4980 and +61-3-9285-7706 are the valid results.
PLEASE ONLY USE <iostream> and <fstream> only haves comments with the program The course records are shown below: Each student has 4 assignments. 108194 9 10 10 10 197526 10 10 10 10 197008 10 10 0 10 197746 10 10 9 10 108154 10 0 10 9 Create an input file ‘CSassignments.txt’ using an editor such as Notepad++ with a student number, then a space, then four assignment marks on one line. The assignment marks are whole numbers and are separated by a space. Your C++ program will read from the file ‘CSassignments.txt’ and write to a second file ‘CSgrades.txt’ which includes the average of the student’s four assignments. e.g. 108194 9 10 10 10 9.75 Your C++ program should work with any number of…
Create a program in C language for reading and writing student records. Submit all necessary source codes and files to run this program (it is recommended to compress all files and submit a single file). First create text file "student_records.txt". The file should look like: Name Surname Quiz 1 Quiz 2 Quiz 3 Ada Lovelace 93 88 97 Babbage Turing Нopper Charles 26 80 70 Alan 74 85 92 Grace 99 87 100 a. Read the file contents and load them into an array of Record structs. b. The record struct has the member variables: o char array name o char array surname o int quiz_1 o int quiz_2 o int quiz_3 c. Write a function that calculates a students quiz average. The function takes a Record struct and returns a double. d. Create two new records for students inside your main program. e. Create a new text file with the new records to a a file called "student_records_new.txt"
the coast redwood tree species, sequouia sempervirens, includes some of the oldest tree on Earth. details concerning individuals trees are given in the tab-delimited text file redwood-data.txt, available at https://scipython.com/ex/bbd. write a python code to read in this data and report the tallest tree and the tree with greater diameter
iii.Now you will implement your algorithm as Python code, modifying the provided Python program Word_List_Flashcards.py. Complete the new version of show_flashcard() by modifying the code so it implements the algorithm you produced in part i. Also modify the docstring for the show_flashcard() function and the docstring for the program as a whole, to take account of the changed functionality and behaviour. Important: Do not make change to any other parts of the program.
You have more flexibility to implement your own function names and logic in these programs. The data files you need for this assignment can obtained from:Right-click and "Save Link As..." HUGO_genes.txt (Links to an external site.) chr21_genes.txt (Links to an external site.) Create an output directory inside your assignment4 directory called "OUTPUT" for result files, so that they will not mix with your programs. Output from your programs will be here! Your program must implement command line options for the infiles it must open, but for testing purposes it should run by default, so if no command line option is passed at the command line, the program will still run. This will help in the grading of your program. Create a Python Module called called my_io.py - You can use the same code from assignment 3's solution. Put this my_io.py Module in a subdirectory named assignment4 inside your assignment4 top-level directory (see the tree below, and see Lecture 7 on how to implement a…
