This question concerns the use of a book cypher to encode a message.Write a program called ‘bookcypher.py’ that accepts:1. The file name for a Project Gutenberg book text.2. A message that is to be encoded.3. A file name for output of the encoded version of the message.The program will create an encoded version of the message by replacing its words with the locationsof words in the book.Say, for example, the message is ‘meet me at the usual time and place’, and the Gutenberg text is‘The Importance of Being Earnest’ by Oscar Wilde.• There is an occurrence of ‘meet’ as the 5th word on the 493rd line of the book text.• There is an occurrence of ‘me’ as the 9th word on the 190th line of the text.• There is an occurrence of ‘at’ as the 6th word on the 8th line of the text.• And so on.Representing a word position as a conjunction of the line number and the index of the word withinthe line, we can encode the message as 493-5, 190-9, 8-6, etc.Sample I/O (user input in bold):Enter the book…

IN PYTHON Problem Statement Given a text file of Zoom users wanting to attend a meeting, filter out a list of users with the domain name @my.fltech.com or @fltech.edu. Then print the list with names (last name, first name) of those with authenticated tech email. Print one name in each new line. Note: the file name is not given by "input()". Instead, assume a file named "zoom_attendees.csv" is available that you need to open/use.

1.15 LAB: Input and formatted output: House real estate summary Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (currentPrice * 0.051) / 12. End the last output with a newline. Ex: If the input is: 200000 210000 the output is: This house is $200000. The change is $-10000 since last month. The estimated monthly mortgage is $850.0. Note: Getting the precise spacing, punctuation, and newlines exactly right is a key point of this assignment. Such precision is an important part of programming. import java.util.Scanner; public class HouseRealEstateSummary { public static void main(String[] args) { int currentPrice = 200000; int lastMonthsPrice = 210000; int = scnr.nextInt(); int estimated Monthly…

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’.…
