- Inside Files (Use Python) Write a program that accepts an integer input, opens a file, and analyzes what and how many types of words are there in a line within the opened file. PROGRAM DESIGNThe program should be able to accept an integer input. This program should be able to open and read a file called tweets2.txt. The integer input represents the order of the line (from 1st to 5th line), within the tweets2.txt file. The program should be able to count how many stopwords, common words, unique words, and overall words are there in the line number input. In Natural Language Processing (NLP), stopwords are defined to be words with no meaning when left alone and with no context. For this activity, stopwords are words that are at most, 3 characters in length, with common words having more than 3 characters. Unique words are words, within the line, that don’t have any duplicates. Whereas overall words are the over all count of all words within the line.

File Encryption: File encryption is the science of writing the contents of a file in a secret code. Your encryption program should work like a filter reading the contents of one file, modifying each character in the input file into a code, and then writing the coded characters out to a second file. The second file will be a version of the first file but written in a secret code. In Notepad or something similar, you will create a file with text in it. It should be several lines long. Your program should read the file character by character and make some change to the character before writing that character to a second new encrypted file. See program 13-8 to see how to read and write one character at a time. You may come up with an encryption technique of your own or use something simple like adding 10 to the ASCII code of each character in the file before it is written to the second file.arrow_forward
